[PHP] Re: Best way to mass mail
* Ryan A [EMAIL PROTECTED]: My client has a dating site and now he wants to mail all his members, he does not want to use any of the already installed mailing lists but wants us to make one for him, he's on a dedicated server. Presently he does not have too many members, just a few thousand (around 3k i guess), I remember reading sometime back on the list that using the mail() may not be the best option...not sure if thats still true. The thing that bothers me the most is if the program times out..., how do I start again from the ones that have not been sent? eg: (10 members) mail gets sent to first 4 members then times out we re-click on the send button and it starts again from one...again times out (this happens 5 times) that means members 1-4 will get the same email 5 times Doing this the hard way would be to connect to the db after each successful mail and mark each member with todays date or something...but I would like to avoid so many calls to the DB if possible...esp if the site grows. Ideas/suggestions? Build a queueing system, and use cron to actually process and mail the list. Longer explanation: I run a mass-mailer for a non-profit, and the way our works is to store all mail information in a database. We then have a cronjob that runs each minute and checks to see if any mailings need to be sent (basically, the absense of a 'sent' flag), and then processes the mailing. Mails are then queued to an MTA -- in our case, Postfix. This allows us to handle bounces (another script is triggered when email bounces back to the reply-to address). So, on your web-based front-end, when you click 'Send', it actually simply places the information in a database queue, and the cronjob does the actual sending. -- Matthew Weier O'Phinney Zend Certified Engineer http://weierophinney.net/matthew/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Since the website http://www.php.net/manual/de/ has no

explode() works the same in both PHP4 and PHP5. Additionally, the manual

I would recommend using \\s instead of \s -- While \s doesn't have any

But in perl type regex's, the \s is a space. Without testing it, I
don't think \\s would match what the OP was looking for (I *think* it
would match '\s'). However, I don't understand why the OP is looking
for a space , followed by a space \s, followed by multiple spaces
\s+a \s{1,} would have done all that just fine.
But in double quotes, \ is seen as an escape, and could be interpreted
differently. Probably the better way to do this would be:
$pattern = '/Charges\s+' . $total . ' x ([^\s]*)/si';

Re: [PHP] Re: run remote shell script
First off, Roger, Thomas, not sure which is your given name -- please
use a mail or news agent that will wrap your lines with linebreaks at 72
characters. Some of us are on text-based clients, and it's difficult to
read your posts when they extend beyond the screen boundaries... ;-)
* Roger Thomas [EMAIL PROTECTED] :
OK. I am able to setup remote key authentication between svrA and
svrB. From svrA I can login to svrB with something like
[EMAIL PROTECTED] www]$ ssh [EMAIL PROTECTED]
and I can also execute a shell script like
[EMAIL PROTECTED] www]$ ssh [EMAIL PROTECTED] /tmp/test.sh
On svrA I have a PHP script like so:
?
system('ssh [EMAIL PROTECTED] /tmp/test.sh someDIR');
?
/tmp/test.sh on svrB is only a one liner like so:
mkdir /tmp/$1
I ran the script from the browser but the /tmp/someDIR is not created :(
Could it be that user nobody on svrA is *not* allowed to connect to
svrB because the public key belongs to user www ? How do I rectify
this ?
In the actual situation, I need to execute a shell script in svrB
(from browser served by Apache on svrA) that only root can run. Please
advise. I am getting very worried.
Okay, I should have been a little more explicit.
There are two ways I've done this. The initial details are different,
but the final call is pretty much the same.
1. Using sudo
'sudo' allows users to run commands as different users. In this case,
we want the user running the web server (usually www, apache, or
nobody) to run ssh, or a script that executes the ssh command, as a
normal user. I usually opt for the latter, and create a script such
as:
#!/bin/bash
exec ssh [EMAIL PROTECTED] /path/to/remote/script
and save it in /usr/local/bin. Then, edit sudoers (usually executing
'visudo' as root), and add a line like
nobody ALL = (username) NOPASSWD: /usr/local/bin/SCRIPTNAME
What this does is to allow the user 'nobody' (or whomever runs the
web server process) to execute /usr/local/bin/SCRIPTNAME as
'username', and they do not need to enter a password to do so
(normally with sudo you do).
You'll need to restart the webserver after granting the sudo
privileges.
In this scenario, the normal user, specified by 'username' above,
needs to have the the SSH keys setup between the servers.
2. Give the web user a home directory
The other option is to setup a home directory for the web user. This
will mean editing the /etc/passwd file to give the web user both a
home directory and a shell; these are teh last two items in the colon
delimited list. A sample entry might look like:
nobody:x:65534:65534:nobody:/var/www:/bin/bash
Once you've done this, restart the web server. At this point, you'll
then need to become the web user briefly in order to:
* generate an SSH key
* send the key to the remote server
Then, on the remote server, add the SSH key to the appropriate user
on that system.
Good luck!

Use ssh. You will have to setup remote key authentication from svrA to
svrB (so that a password will not be needed), and then in your script
you would call:
system('ssh svrB /path/to/scriptToRun');

Re: [PHP] How to suppress HTTP headers?
* Thomas Capote [EMAIL PROTECTED]:
3) The header() command inserts or replaces headers to be sent by PHP.
However, header() (with no arguments) does not suppress header output, it
simply generates an error. Even if something like header('Content-type:')
suppressed the 'Content-type' header, how would we suppress all header
output including the status line ('HTTP/1.1 200 OK')?
The HTTP/1.1 200 OK is a header sent by your web server; PHP has NO
control over headers sent by the web server -- only those that PHP
appends to them.
5) Mr. Lynch is right: this is NOT an HTTP compliant exchange. This is a bug
in the client machine that cannot be fixed (by me), but must be worked
around somehow.
This is the real nut of the problem.
Tough little problem, eh guys?
I see three possible avenues to a solution.
1) Find some PHP command that will suppress header generation, or simply
circumvent it, if only as a side-effect.
Already noted, cano't be done.
2) Get Apache to not send headers for this page, maybe through SSI
directives, .htaccess file, or some other mechanism.
I don't think there's a way to do this -- HTTP headers are part of the
HTTP protocol, and that's what Apache tries to implement. But I can't
say with 100% certainty that someone hasn't done it. Search on the
apache web site.
3) Write my own mini-server (to listen on port 6237 or something) to handle
these requests using socket calls in PERL, Java, or even the PHP CLI. I'm
not sure I could pull off programming something robust enough, frankly. I'd
rather hijack Apache to do the heavy lifting.
I think this is likely to be the direction you'll need to go. This sort
of thing actually isn't too difficult to do -- I've used and tinkered on
PHP chat server implementations that do similar things. Perl has a
wealth of tools for creating net servers which, again, make this stuff
fairly trivial.
Good luck!

CLI. Odd. Not sure I had to do that when I wrote a few CLI scripts
before. Oh well, something to play with another day (don't have time
to check it right now).
So another thing I may be wrong on.. but a thought.. If you use the
header() command, does it prevent the web server from generating it's
own headers?
I believe your header() commands only REPLACE any headers PHP would
have sent, but any other headers it's gonna send, it's still gonna
send them.
That is, if you send out htmlbodySomething/body/html does the
web server automatically generate the headers but if you use header()
it uses what PHP generates rather than it's own?
If so.. can you just do:
header();
With nothing in it to suppress headers?
I think that will suppress headers... by issuing an ERROR that a
required argument is missing :-)
Or can you do something like:
header(xmlstuff/xml);
No.
That is not a valid header, for starters.
You MIGHT be able to wipe out the headers PHP sends by doing
something like:
header(Content-type:); //Wipe out Content-type:
but I wouldn't cound on it.
Sounds to me like the remote server isn't actually using HTTP at all.
HTTP without headers is just not HTTP.
You may want to write your own server in PHP using sockets -- but
then you'll need to convince the remote server to connect/use that
different server you have written. Either connecting on a different
port, or to a different domain, or a different URL (maybe) so you can
configure your box to use your server for these weird requests.

[PHP] Re: optional argument when creating a function
* D A GERM [EMAIL PROTECTED]:
I'm throwing a warning on a function I created. I
thought a in front of the argument was supposed to
make it optional. Is there something else I need to do
make that argument optional?
As others have noted, the ampersand tells the function to grab a
reference to the variable passed.
There are two ways to do optional arguments:
1) Set a default value for the argument (must be last argument in the
list, or else all other arguments in the list must also have default
values):
function doEmail($username, $link = null) {}
function doEmail($username, $link = null, $linkName = '') {}
2) Parse the argument list via the func_* functions:
function doEmail($username)
{
$argCount = func_num_args();
if (1 $argCount) {
// Retrieve second argument, from a 0-based array:
$link = func_get_arg(1);
}
...
}
function doEmail($username)
{
$argCount = func_num_args();
if (1 $argCount) {
// Retrieve all arguments
$args = func_get_args();
// Remove $username from it
array_shift($args);
// Get $link:
$link = array_shift($args);
}

Use an OS that either doesn't have an end-of-life for support, or which can be upgraded to a new version without breaking everything. I've used Redhat and Fedora, but will never use them for production servers again -- after a couple years getting out-of-date, it becomes next to impossible to find packages for them, and upgrading to a new version almost always requires an attended install, and usually down time. Debian and Gentoo are very nice in that you can upgrade packages as they become available, usually with no issues.

While I've dabbled with PHP5 and made my framework compatible with it I haven't bothered to make a wholehearted leap into it. The following reasons basicly sum up why, and are probably common amongst those that aren't leaping into PHP5. - Better the devil you know than the devil you don't. Many PHP developers have spent years using PHP4 and know it inside and out and have come to terms with all of it's deficiencies... as few as those may be once you learn how to adapt to them. This is a fear-based argument. Arguments like this prevent innovation. Yes, I know PHP4's deficiencies and quirks inside and out -- but that doesn't mean I should stick with them. If I were to use that argument, I would never have left perl for PHP. PHP5 actually *fixes* many of PHP4's deficiences and quirks -- such as how objects are passed, how errors are handled, etc. I jumped onto PHP5 because I wanted a PHP that worked *better*. - A multitude of code already exists that is known to work under PHP4 but can be expected to have quirks when run under PHP5. Explain. My experience, while limited, has shown that well-written PHP4 code generally works quite well under PHP5. - Much of the code written in PHP4 works without the new features of PHP5 and so there's no compelling reason to invest time and resources for 0 ROI other than compatibility with PHP5. Except that if you stay on an old version of PHP4, someday it will be deprecated and you'll *have* to upgrade. I, for one, would rather take smaller steps over time between versions than need to scrap an entire project and rewrite it from the ground up when the version reaches end-of-life. The ROI may be zero or small now, but priceless later. - PHP5 had a large focus on bringing missing OOP features to PHP that have little merit to those who write mostly procedural code. The OOP rewrite was only a portion of the changes brought into PHP5. What about exceptions, or the mysqli support, or the simplexml addition, or...? There's a lot of stuff in PHP5 that procedural programmers can utilize. - Accelerators for PHP5 are not particularly good at this time, so unless you've got cash to shell out to Zend (which can be expensive for the little guy) then why move from your trusty PHP4 accelerators that already get the job done satisfactorily. As Rasmus noted under separate cover, the APC project has made tremendous headway in the past few months, and is working fairly well with PHP5 at this time. -- Matthew Weier O'Phinney Zend Certified Engineer http://weierophinney.net/matthew/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

My observation was that more people jumped to PHP4 from PHP3 than have so far from PHP4 to PHP5. And PHP5 has hardly just started to roll out; the official 5.0.0 release was over a year ago. sure it is just a 'versioning' thing, but right now huge numbers of php users aren't using php5 (including me) on production environments, let alone start talking about php 6. And why aren't you using PHP5? Is there any specific reason? Is it because your service provider doesn't offer it? If so, ask them why -- and report it here. As soon as PHP5 hit stable, I started using it, and I've never looked back. Performance is better, and there are many features -- exceptions, the new OOP model, autoload, iterators, etc. -- that simply have no analogs in PHP4. anyway, i think i will be with php4 for a long time to come. Please tell the list why -- what does PHP4 offer over PHP5 for you? I honestly want to know, and I'm sure there are others who would be interested to see why people are not making the switch. kinda of how apache2 hasn't been a real success over apache1. That's a completely different story. Apache2's internal structure adds thread support, and since many loadable modules are not necessarily threadsafe, using them with Apache2 often negatively impact performance (PHP, for instance, must be run non-threaded because many of the libraries against which it links are not threadsafe -- and thus running PHP on Apache2 is much less efficient than on Apache1). The differences between PHP4 and PH5 are much more trivial, and those people who choose to use the features of PHP5 are not going to lose performance or functionality -- actually, quite the opposite. i just hope php doesn't end up being bloat-filled with the not-so-useful thing just taking up resources. I think one of the things I like most about PHP is that you can easily compile it with *only* the features you need -- it only needs as much bloat as you need to use it. -- Matthew Weier O'Phinney Zend Certified Engineer http://weierophinney.net/matthew/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Re: dynamic object instances

I would like to create an object inside a function with its classname
and a parameter list submitted by the function call.
function create($class, $parameter) {
$obj = new $class($parameter);
return $obj;
}
This is working very well. But I have not every time the same count of
parameters for a class constructor.
If this is a normal method call of an object I can realise it like this:
$ret = call_user_func_array(array($obj, 'method'), $parameter_array);
The $parameter_array contains as many entries as the function needs.
Works well too.
But how can I write a function to instance objects with various count of
parameters in the constructor?
I know, can do this with an eval. But I would like to find a solution
where I don't need an eval.
Use the func_* functions, along with array_shift(). In addition, you'll
need to use either a standard-named static instantiator, or the class
name as the constructor method:
function create($class) {
$args = func_get_args();
array_shift($args); // remove $class from the args list
// Do this if using a standard-named static instantiator method
// across classes; in this case 'init':
return call_user_func_array(array($class, 'init'), $args);
// Or use a function named after the class name as the instantiator
// method (ala PHP4):
return call_user_func_array(array($class, $class), $args);
}

I would recommend you try and be more consistent in the way you
present your code - it makes it easier to maintain and debug - granted
php doesn't care about the layout - you can write everything on a single line
if you really want. google on Coding Standards - pick a style your eyes like

Matthew but it's perfectly valid to define a function inside an if()
block... It generally gets doen in apps where they have to support older
versions
of php and conditionally define functions if they don't exist e.g.
if (!defined(array_push)) {
function array_push($arr, $val) { /*stuff*/ }
}
D'oh! I was thinking this was an anonymous function (ala perl), and of
course it's not. Good catch, Jochem.

I got 1 when running this -- just as I would expect. Are you sure it

Basically, if a property is undeclared, it is assumed public, so you can
set undefined properties without issue. If defined private or protected,
the calling script will not be able to alter the value.

[PHP] Re: Class constants
* Marcus Bointon [EMAIL PROTECTED]:
I'm not sure if this is a bug or a feature, but it seems you can't
use class constants to set default values for class properties. You
can, however, use them for default values for method params, e.g.:
class foo {}
const BAR = 100;
private $thing = self::BAR;
function wibble($a = self::BAR) {
echo $a;
}
}
In this case $this-thing will be undefined, but wibble() will get
the correct default value for $a.
Comments?
This has been the case since PHP4. From http://php.net/oop:
In PHP 4, only constant initializers for var variables are allowed. To
initialize variables with non-constant values, you need an
initialization function which is called automatically when an object is
being constructed from the class.
What is meant by 'constant initializers' is that you cannot define class
variables based on variables, constants, or globals -- defined in the
class or otherwise. So, the following is okay:
private $thing = 100;
But, as you saw, the following will barf:
private $thing = self::BAR;
private $thing = BAR;
private $thing = $_SERVER['SCRIPT_NAME'];
// etc.
So, in other words, the issues you're seeing are consistent with the
documentation.

[PHP] Re: WAMP Performance Tuning
* JM [EMAIL PROTECTED]: I'm quoting out a system for a Windows/Apache/PHP/MySQL database-driven web application I've written. I've never gotten too deep into determining what is the actual performance bottleneck in this scenario. Is it the disk or the RAM? I expect about 75-100 users during business hours. 90% will be in the LAN and 10% will go over the WAN. I'm wondering if I can get good performance out of a small system with 2GB RAM, 1GBps NIC, and a SATA disk or three spanned. You don't indicate how many queries are made on a given page, how much data is handled, etc., Without seeing some code, it's hard to say what the bottleneck for performance will be. I've done some fairly critical stuff that, because I took the time to optimize the database, optimize how much data gets displayed at a given time (pagination is a *good* thing), streamlined the code to minimize file and database calls, and setup the box to only run what was necessary for serving pages, I was able to get away with using a sub-400Mhz box with 384MB of RAM and a 20GB drive (this was a LAMP setup). And it performed well, even with decent user load. Disk calls are always more expensive than RAM calls -- but if you're hitting a database, you're hitting the disk anyways (unless the queries are getting cached). Run benchmarks, and try to minimize the number of file calls and database calls to what is absolutely necessary. Consider dumping Windows for a Linux flavor, or one of the BSDs. You can tune these better to only run the services needed for the web stack (Apache, MySQL, cron, firewall, formail/msmtp/sendmail). Because of the shared-nothing architecture of PHP, you really don't need heavy hitting boxes in order to get good performance.

* Taksam [EMAIL PROTECTED]: I finally installed Apache 1.3.3 and PHP 5.0.4 engine and made my first PHP page and it works! thanks for your help! And didn't use an IDE, just UltraEdit :) but, I WILL use and IDE someday anyway. The beauty of PHP (and most scripting languages) is that you don't need an IDE ever. A good editor with syntax highlighting will get you where you need to go reliably. I use vim. Now, my question is: can I use Apache version 2 with PHP? And, even if I can use it in my development environment... is it safe to use Apache 2+PHP in a production environment? Yes. But there *are* issues with it. The biggest thing Apache2 introduced was threaded processes. Unfortunately, PHP isn't necessarily threadsafe -- not all of the libraries it can be compiled are threadsafe, and many are in a state where thread status is simply unknown. (My understanding is that the PHP core is probably threadsafe; it's the extensions -- database, mail, etc --- that you can't be sure of. Somebody correct me if I'm wrong.) The upshot is that when compiling PHP to work with Apache2, you have to compile it to work without threads -- which means that, in the end, there are no performance gains, and, in most instances, PHP performance actually suffers under Apache2 (up to 30% decrease). John Coggeshall announced today that he is going to work to get PHP completely threadsafe, but my guess is that this will likely be a late version of PHP 5.1, if not even another minor version (5.2, 5.3) before it's complete.

Re: [PHP] db insert question
* JamesBenson [EMAIL PROTECTED] :
Thanks for your reply, your example demonstrates what i was doing but
does that do a MySQL query for every piece of data?
So 20 form values would be 20 db queries, would that not consume a lot
of resources?
Not necessarily. If you use a prepared statement first, then execute it,
you'll get excellent performance. If you're interested in prepared
statements, or don't know what they are, look at DB abstraction layers
like PEAR::DB, PEAR:MDB(2), and ADODB -- they utilize them. As an
example:
$sql = INSERT INTO someTable(field1, field2, ...) VALUES (?, ?, ...);
$insert = $db-prepare($sql);
foreach ($data as $vals) {
$db-execute($insert, $vals); // Assuming each element of $data
// is an array of values
}
Basically, you prepare a SQL statement that contains placeholders for
the values. Then when executing the statement, you pass an array of
values equal to the number of placeholders in the statement. The
benefits are (a) speed, and (b) security. Regarding (b), the values are
quoted in a proper format for your RDBMS, so you don't need to worry
about escaping each and every value -- the DB abstraction layer and/or
the RDBMS takes care of it for you.
Is their another way?
Yes -- Build your SQL first, in the following format:
INSERT INTO someTable(field1, field2, ...) VALUES
('rec1Field1', 'rec1Field2', ...),
('rec2Field1', 'rec2Field2', ...),
('rec3Field1', 'rec3Field2', ...);
And some PHP code that could help create this:
// Beginning of SQL
$sql = INSERT INTO someTable(field1, field2, ...) VALUES ;
// Loop through records to insert
$INS = array();
foreach ($data as $values) {
$final = array();
// Loop through each value in the record and quote it
foreach ($values as $val) {
$final[] = sprintf('%s', mysql_real_escape_string($val));
}
// Join them with commas and enclose all in ()
$INS[] = '(' . implode(',', $final) . ')';
}
// Finally, join all the records with commas, and end the SQL with a
// semicolon
$sql .= implode(',', $INS) . ';';
$result = mysql_query($sql);

Currently im just assigning each one a variable but that is messy and

maybe do the same to enter it into a database?
Thanks for any help.
A generic question begs a generic answer:
foreach($formdata as $thisdata){
$result=mysql_query(insert into ... values($thisdata) where ...);
}
Hope this helps, but it would be useful to have code examples, etc so that a
more relevant answer could be rendered.

[PHP] Re: Content Header
* Christopher J. Umina [EMAIL PROTECTED]: Hello! I currently have a script which streams data out of a MySQL database, and prints the content headers correctly, however, when I use the following line: header(Content-Disposition: attachment; filename=\. $filename .\); it prompts the user to download the file each time they go to the site. The problem is, I want the filename to be in the header, incase somebody right clicks and saves the file, but I don't want the user to be prompted to download the file when they're just trying to look at it. Does anybody know a way I can achieve this result? As long as the Content-Disposition: attachment header is present, the browser will believe a file is being sent. One solution is to have two different links, with an optional download flag in the query string. Then, in your script, generate the Content-Disposition header for 'download' requests, don't otherwise. -- Matthew Weier O'Phinney Zend Certified Engineer http://weierophinney.net/matthew/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] getting file size before upload
* Jay Blanchard [EMAIL PROTECTED]: [snip] I know it is a often asked question, but after googling for about 2hours and trying out some wired examples I am still not any closer to a solution. So I was hoping to find expert advice here. I want to save the user the hastle of uploading a 2MB file and waiting for a long time for an error message that the file is to big. Is there any usefull workaround in warning the user that he is about to upload a 2MB file and only smaller files are supported? I tried around with megaupload: http://sourceforge.net/projects/megaupload to get a progress bar and to get the file size prior to upload, but that somehow does not work the way I want it to. Is there an easier solution without perl,just with PHP or/and JS? [/snip] http://www.php.net/stat The OP wants a solution that is client-side -- stat() would be server-side. And, to answer the OP's question, no, there is not a reliable way to do this. You can provide some hints via the HTML form -- set hidden keys for MAX_UPLOAD_SIZE, for instance -- but many browsers ignore these. My understanding is that it's possible to use javascript in some cases to determine the file size on the upload element's population, but that is going to be unreliable as well, due to differences in client OS and browser javascript implementations. The easiest solution is to simply provide some warning text indicating that the file size should not exceed a certain threshold -- and give back a nice, big error message when it does so they know why the upload failed. -- Matthew Weier O'Phinney Zend Certified Engineer http://weierophinney.net/matthew/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I am trying to make like a catalong and have all the files (including pics) and everyone can see. is this possible? Sure -- if you're using a MySQL database, just use a BLOB field and put the data in as you would a string of text. Be aware of your storage requirements, however. There are several BLOB types -- TINYBLOB, BLOB, MEDIUMBLOB, and LONGBLOB -- so make certain you choose the one that exceeds the maximum file size you expect to place in the DB. Additionally, there are performance hits to storing images in a database. Another approach that is widely used is to store the images on the filesystem, and then image *details* -- location, size, caption, photographer, etc. -- in the database. This is typically faster, and will reduce the number of DB calls. -- Matthew Weier O'Phinney Zend Certified Engineer http://weierophinney.net/matthew/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

In some of my older R textbooks a form is returned to the same page by using R echo $PHP_SELF no just $PHP_SELF R is this just used in older versions of php?? Does the it make a R difference what one is used? PHP_SELF is part of the $_SERVER super global, you should really access it like this: $_SERVER['PHP_SELF'] To answer your question though, it's just a variable - if you want to output it into your form action then you can do either: ? echo $_SERVER['PHP_SELF'] ? or ?=$_SERVER['PHP_SELF']? Either would work. Actually, to be truly portable, it should be: ?php echo $_SERVER['PHP_SELF']; ? Not all hosts have short tags enabled in their PHP installations. Additionally, you have to be careful with PHP_SELF. On web servers that allow PATH_INFO -- i.e., arguments to the script in the form of path information, like '/path/to/script.php/more/path/info -- PHP_SELF will contain the path to the script PLUS the contents of $_SERVER['PATH_INFO'] -- which leaves PHP_SELF vulnerable to cross-site scripting attacks. For some discussion on this, see: http://blog.phpdoc.info/archives/13-XSS-Woes.html If you're using Apache, the safer bet is to use $_SERVER['SCRIPT_NAME']; otherwise, use PHP_SELF, but filter it to exclude the path information. -- Matthew Weier O'Phinney Zend Certified Engineer http://weierophinney.net/matthew/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Re: Help - need to quickly optimize a record count!
* Brian Dunning [EMAIL PROTECTED]: I am cross-posting this to the PHP and the MySQL lists because I'm not sure in which technology my solution will lie. I have a pretty busy PHP/MySQL site that executes the following query a lot: select count(*) as `count` from terms; My MySQL account was disabled by my ISP because this query was causing resource issues, so I need to find a different way to know the record count in that table. A few records are added once every 5 minutes by a cron job. The record count is constant the rest of the time. No records are ever deleted. Is it possible to create some kind of server-side variable, in which the cron job could store the record count, which would be accessible to all scripts, and would stay the same until it gets reset? Or is there a less-intense MySQL query I should be using instead? If the cron job is running anyways, you could run the count query after updating, and then store the count in a file. Then have your scripts read from that file. You could also store the count in the database. Another possibility is to run the count once, and then each time you add records, add the count of new records to that count. Again, storage could be in either a file or a DB. Either way, you're down to doing the count at most 12 times per hour, instead of every time your scripts are hit. -- Matthew Weier O'Phinney Zend Certified Engineer http://weierophinney.net/matthew/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: Re[2]: [PHP] PHP vs. ColdFusion
* Andrew Scott [EMAIL PROTECTED]: CF is very rapid development, and you might say the same about PHP. The point is that these are all the things you need to take into consideration, the cost that it would take to develop and maintain in either language, as well as cost involved in the need of the application having to be a true enterprise solution. I am not here to bag php, I am here to make some points about the cost of the application in the overall scenario. Would you develop in a language that you know could not deliver an enterprise solution if in 6 months that's what you really need, and how would you look if you recommended a language because it was free, but in time had to spend more again to make it fully scalable to an enterprise level if it needed it. You've insinuated several times that PHP is not 'scalable to an enterprise level'. Could you perhaps explain what you mean by this? One informal definition for 'enterprise framework' I've read recently is an enterprise framework allows the end-user to drop in only the business logic to make it work; they do not need to add anymore programming to the framework (http://benramsey.com/2005/05/09/what-is-an-enterprise-framework/) Now, I've seen a number of PHP frameworks where this is the case; you drop in a config file of some sort, point your application to it, and voila! Solution delivered! That doesn't address scalability, however. So, let's look at that. I'm not sure how CF scales, not having been in a CF shop. However, I know what I can do to scale PHP: * Use code optimizers/bytecode caches (zend, apc, eAccelerator) * Build an LVS-HA cluster for a web farm (i.e., increase the number of machines able to serve data and pages) * Focus on code optimization (i.e., make my code as efficient as possible) (As an aside, the beauty of a cluster is that you can add or subtract machines without the public noticing; the site remains up. Additionally, since all the director does is pass requests to the nodes, and possibly relay the responses back to the requestor, you can have machines of just about any configuration running on the backend -- Linux, FreeBSD, Windows, etc. -- so long as they speak the HTTP protocol.) Could you please share why you feel PHP isn't enterprise ready, or why CF is more enterprise ready?

Only after approaching similar problems several times will you find a more general, elegant solution that could solve all of them. It's the repetition of the problem, and the differing approaches that inform your ability to program towards it. The only way to get there is doing lots of coding. Re-write some old code of your own. Amazingly instructive, and often leads you to new heights. Plus your old stuff suddenly has a lower maintenance cost, for some odd reason... :-) I do this all the time. It's invaluable. Sometimes you find some little gems -- and most of the time you discover how much you've learnt since then, and you refactor it and make it better. Publish some articles or code snippets on your site. The act of trying to explain what you did to somebody else will open up worlds of understanding. You never really understand something until after you've taught it to somebody else. :-) I keep a blog, mostly about my PHP development. I do this in part for myself. If I act as if I'm explaining it for someone else, I often get to the meat of an issue or problem -- a place I might not have visited had I not spent that extra time trying to understand it enough to explain it.

At least, it's okay for me. :-) [shrug] I work with another developer, and we're constantly refactoring each other's code. But the brilliant part of it is that we then learn from each other as well. Do some code review for another developer some time. As Richard notes, writing lots of code will improve your coding ability; so will *reading* lots of code. snip Ooooh. At the risk of being branded a heretic, try to pick up another language or two. Start with something a whole lot like PHP. Maybe Perl, or even C. I wouldn't understand PHP half as well as I do if I didn't know perl already. I still use perl regularly; sometimes it's suited for the task. But that's another reason to learn other languages -- to determine when PHP is the right tool for the job, and when another language is. Well, that got long and philosophical, didn't it?

Re: [PHP] PHP vs. ColdFusion
to develop in coldfusion. But you may need to spend money for the actual application server. I'm not going to debate the merits of PHP versus ColdFusion; I'm not familiar enough with the latter to make an objective case. However, I think the important thing here is that if you know a language inside out, it will almost always be easier to do development in that language than in one to which you've had less and less frequent exposure. PHP is certainly a good web programming language. So is ColdFusion. I'm choosing PHP because: * It's free; I don't need to purchase anything in order to run programs written in PHP. * No vendor lock-in. I can run it on a variety of web servers, and on a variety of OS flavors. * Variety of plugins. I can mix and match a variety of RDBMS drivers, choose what extensions I may want (IMAP is unnecessary, but I want FTP, etc.). * Community support. I don't have to pay for support, and there's a large community of developers upon whom to draw. Some of these may be true for ColdFusion as well. What the OP needs to do is determine what merits PHP or ColdFusion may have over the other, as well as what demerits might be present for each, and then evaluate those in the context of their work environment. -- Matthew Weier O'Phinney Zend Certified Engineer http://weierophinney.net/matthew/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

A package can be very bloated and still be extremely useful to someone who doesn't have the time or the ability (not to say you don't have the ability) to implement similar functionality themself. Correct; ability isn't the problem; time often is. aside However, I also find that I start by creating some functionality myself, and then as special cases start popping up, modifying, adding on... and then discovering that an equivalent PEAR package already exists that covers all these special cases and a number I hadn't thought of. (Pager comes to mind). I often wonder if what is meant by 'bloat' is that those claiming 'bloat' feel that the PEAR code covers too many special cases -- cases they have not encountered or do not expect to encounter.

Actually, my argumentation was not specifically about 'PEAR is bloated', but more along the lines of the many comments I've seen on this list to the effect of 'PEAR sucks'. But I've also seen many comments like the one from Catalin about 'PEAR... is kinda bloated', without indicating why they think so. I should have been more clear in my rant that I'm tired of hearing generalized negative statements against PEAR that are then unqualified (i.e. no substative reasons given). The statement 'PEAR is bloated' doesn't indicate in what way it is bloated. Unfortunately, many read 'bloated' as a negative, and thus as an indication that one should stay away from the code; thus may a developer who has a problem that could be easily solved by PEAR code be turned away from it. Additionally, saying 'PEAR is bloated' doesn't take into account the fact that PEAR is a large group of packages, and that each package within PEAR should be judged on its own. For instance, I've heard and read some good arguments as to why the PEAR package itself is bloated; however, if you've ever taken a look at Cache_Lite, you'd probably agree that it is anything *but* bloated. (The authors of that package put no dependency on PEAR.php, and coded with a goal of efficiency and optimization.) snip Then explain what you mean by 'bloated'. Just throwing out that phrase doesn't give anybody any extra information -- just your opinion. Can you give some examples to *qualify* your statement that PEAR is bloated? That was the main thrust of my rant -- people throwing out unqualified opinion statements like 'PEAR sucks' or 'PEAR is bloated' without explaining *why*. So far all the reasons you've given to indicate why PEAR is NOT bloated have nothing to do with why PEAR is or is not bloated. You have clearly indicated a passion for it, a usefulness from it, even established a decent amount of superiority in it, but if anything your arguments have indicated why it is bloated in many respects: - covers all of these special cases (and by virtue probably more) - I can see a point in wanting to keep code trimmed to necessary cases though - rather have all my bases covered It is my opinion and the opinion of many others that the fact that PEAR covers so many exceptional cases, the fact that PEAR implements such a generalize error handling system, the fact that PEAR do so much generic everything to make everone happy, that these elements that make it so versatile also make it feel bloated. It's like kicking a soccer ball to the goal, but rather than take the most direct route, you take the fringe route to cover all your bases...ultimately this is generally a longer path. And, as I said, I can completely see your point. But, as noted above, saying PEAR gives a false impression that *all* code in PEAR is bloated, which is simply not the case. On the other hand, you've also given a very nice overview of *why* people feel some code in PEAR is bloated -- which is what I've been driving at. You've qualified the statement, and that's worth much more than simply tossing the phrase off. Thank you!

Indeed, the DocBook requirement for PEAR documentation is a major issue even with PEAR developers. For example, I want to use the DB_Pager module but there is *no* end user documentation, all I have to work with is some poorly formatted information pulled from the API comments. Just an FYI: Use the Pager package instead. Under doc/Pager/examples in your PEAR directory is a Pager_Wrapper.php script that shows how to use it easily with DB. Pager, unlike DB_Pager, is well documented. There are also a lot of packages (again, less well known ones) that haven't been updated in a long time, in some cases several years. I'm not saying that PEAR in general is a stale project, or that it's no good (on the contrary, I use several of the packages on my sites and they're very useful), but I do get the feeling that the non-core packages have been left to rot both in terms of updates and documentation. This is an issue I've seen PEAR attempt to address this past year through the introduction of its QA team. But the process is still far from tuned. The above are *great* examples of why people might not choose PEAR -- and constructive ones at that. Thanks. I've used both PEAR and CPAN for a few years now and I've noticed that CPAN tends to win hands down in terms of documentation and updates. That might just be down to the particular packages I've happened to use but given a choice I know which one I'd rather use. Ah, a fellow perl developer! CPAN is, for me, *the* reason to code in perl. The perl culture is one that includes testing and documentation as the norm -- and that has made for a solid library in CPAN. However, the TIMTOWDI principle also means that forking is a foundation principle. This can be seen as either a pro or a con: pro, in that you have choice in what module to use; con, in that you then have to evaluate a number of modules. After having said that, though, I'll continue coding PHP anyday! -- Matthew Weier O'Phinney | WEBSITES: Webmaster and IT Specialist | http://www.garden.org National Gardening Association| http://www.kidsgardening.com 802-863-5251 x156 | http://nationalgardenmonth.org mailto:[EMAIL PROTECTED] | http://vermontbotanical.org -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

* Joe Muddah [EMAIL PROTECTED]: I am trying to design a website archeticture. Does anyone have any links or experience with archetictures that actually work. Any ideas of how to layout a website would be greatly appreciated. This is what I am thinking of doing 1)Seperate Logic from presentation Using Templates (Smarty) for presentation Using PHP Objects for logic (no echo statements) 2)Use Controllers to bring together logic and presentation I don't really have an idea yet of how to do this. I am thinking about having something like a page variable to figure out what template to output, action variable to figure out what objects are called (save, delete, etc.). All this would be under a switch statment. Example: shamelessSelfPromotion I'm the author of the PHP port of Perl's CGI::Application, Cgiapp.class.php (http://cgiapp.sourceforge.net/). Cgiapp is designed for exactly the usage you present above. It is a lightweight, abstract Controller class upon which you build your application class. All screens are handled as 'run modes', and each run mode is a method in the class. Templates are used by default, with Smarty being the default engine, though the template methods may be easily overridden to accomodate other template engines (several users indicate they use it with Savant). Additionally, it's built to allow the creation of reusable, customizable web applications. Your libraries can be placed in one location, and then instance scripts in your document root may customize the behaviour of the application through parameters passed to the constructor. I've used it on two of the sites below, garden.org and nationalgardenmonth.org, both of which get very high traffic. Additionally, I've used it on a client site for a Fortune 100 company. It's robust and tested.

This doesn't demonstrate what the OP was talking about, which is initial
assignment of an object using a reference operator. The results of this
make perfect sense to me -- the references are passed exactly as I would
expect.
Let me rephrase my question to you: is there a reason to do the initial
object assignment using a reference operator using PHP5? I.e., is there
a good reason to do this:
$foo = new Foo();
instead of:
$foo = new Foo();
I haven't seen any reason to do the former case using PHP5.

Your original response said that the above notation was unneccessary, I took that to mean the operator for reference. Looking back I see ow that your comment was ambiguous, and I agree there is no need for the when assigning a new object. I was merely clarifying that references and normal assignment are not synonymous for objects in PHP 5. Okay -- good to see that we're on the same page. I was worried I'd missed something critical in the manual! References aren't easy to wrap your head around; I, for one, am very happy that I don't need to worry about them nearly as much with PHP5 (syntax is now, do what I mean). Interestingly enough, however, the PHP4 behaviour is actually much closer to perl's -- which should have made it easier for me (being a perl programmer), but somehow didn't. -- Matthew Weier O'Phinney | WEBSITES: Webmaster and IT Specialist | http://www.garden.org National Gardening Association| http://www.kidsgardening.com 802-863-5251 x156 | http://nationalgardenmonth.org mailto:[EMAIL PROTECTED] | http://vermontbotanical.org -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

The results of this make perfect sense to me -- the references are passed exactly as I would expect. But not exactly as I would expect! I thought that all objects were created as references, but apparently this is not the case. Here's what happens (in PHP5) with the statement '$obj = new Class();': * the 'new Class()' construct creates an object * it then returns a reference to the object * assignment is then to the reference Thus, $obj is actually a *pointer* to the object -- not the actual object. Is there some kind of dereferencing going on when you're using an object on the right side of the assignment (=) operator? No. It's simpler: you're simply passing around a reference to the object. Before, in PHP4, when you would use assignment, the variable on the left side would receive a *copy* of the object on the right -- a clone of the object. *UNLESS* what you had on the right side was a reference; then it would clone the reference, meaning you have the same behaviour as in PHP5. This is why the $obj = new Class() idiom occurred in PHP4; that way you could pass around your object safely, because you were simply passing around a reference to an object. PHP5 simplifies this by simply assigning the object reference only in the first place. -- Matthew Weier O'Phinney | WEBSITES: Webmaster and IT Specialist | http://www.garden.org National Gardening Association| http://www.kidsgardening.com 802-863-5251 x156 | http://nationalgardenmonth.org mailto:[EMAIL PROTECTED] | http://vermontbotanical.org -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] Re: security question...??
* bruce [EMAIL PROTECTED]: you miss what i'm saying, and what my point is. i as a server communicate with clients. under normal situations, the client is used to communicate back to the server. but what if someone created a 'client' that looked like IE, except this client was really sending the information entered by the user to who knows where... I can see what you're saying here. But I can already see some other issues that make this hard, if not impossible, to deal with: * Proxy server between client and server. If there's a proxy server between the client and server, it's possible the proxy server is munging the browser agent strings. If that's the case, we simply will not know for sure what the browser is -- or even necessarily what IP from which a request originates. * Many browsers allow the user to set the browser agent string. Look through your server logs some time -- you'll see some incredibly creative browser strings in there. This ability also allows one browser to spoof as another. For instance, I know in the past that Opera would allow you to select on the fly whether you wanted the browser agent to be reported as IE (to get IE-specific CSS files). * Who's going to keep the database of 'trusted' client browsers? You mention MS IE as one such... but I sure as hell wouldn't place it on *my* list. And, knowing how easy it is to spoof browser agent strings, I wouldn't place Firefox of Opera on there either... oops! there goes over 98% of my browser share! Limiting based on browser directly contradicts the purpose of the web. More on that below. snip this issue has nothing to do with HTTP protocols. Maybe I'm seeing this entirely differently than you, but I think it's *all* about HTTP protocols. Web applications are written on top of HTTP, and HTTP has a very fluid specification, because from the very beginning HTTP was designed to deliver HTML documents in an agnostic way -- so that they may be read from text-based browsers, graphical browsers, browsers on TVs, etc. The fundamental building block, then is HTTP, which is a series of stateless transactions. The servers and clients speak across this protocol, and in between transactions have no inkling of the others' existence. Furthermore, an HTTP server should not care what makes the request, so long as it is well formed; if it is well formed, it returns a string (a document). That's all it's supposed to do. You mention above except this client was really sending the information entered by the user to who knows where. If they're not getting to my site, or the request is getting redirected elsewhere, I can't do anything about the situation; my server knows nothing about it. If they are, there are a number of ways to maintain some awareness of particular users between requests; sessions and cookies come to mind. It's very easy to create server-side tags in sessions to prevent session hijacking very much like you describe (using things like dates, browser agent strings (looking for consistency between requests), etc.). hope this provides more clarification as to what i'm dealing with, and why it should be important to people who write secure apps/sites/systems. if you only focus on the server, you can't really say your service is really secure... On the whole, I'm less worried about hijacked client browsers than I am about zombie networks making repeated requests to my systems (DDOS on port 80). I can use the tools of HTTP and PHP to track users across requests. I personally think these are plenty powerful -- and help me provide a service that can be agnostic of the device using it. I understand your concerns, but they come more from a world where environments can be strictly controlled, and the web ain't one of them. -Original Message- From: Matthew Weier O'Phinney [mailto:[EMAIL PROTECTED] Sent: Monday, June 20, 2005 1:23 PM To: php-general@lists.php.net Subject: [PHP] Re: security question...?? * bruce [EMAIL PROTECTED]: a number of you write apache/web/server apps that deal with secure information.. in doing some research it occured to me that a potential weak link is on the client side, regarding the browser? how many of you actually attempt to verify that the browser being used by the client is indeed a legitimate (non-hacked) browser?? or is there even a way to do this? or should i just go back to sleep..??

* bruce [EMAIL PROTECTED]: if you're going to be writing apps that deal with sensitive information, you better damm well give some thought as to how secure the client is, That's what encryption using public/private keypairs is for.

That way the server doesn't *need* to know what the client is, so long as the request is made over HTTP and the server is able to decrypt the data sent. or even if the client is actually valid!

The problem is that the PDF file that is sent is corrupted for acroread (xpdf

Likely what's happening is that there's extra output happening after

there's no whitespace after your closing PHP tag (or simply don't
include a closing PHP tag).

[PHP] Re: Retrievable weather service info?
* Murray @ PlanetThoughtful [EMAIL PROTECTED]: Just wondering if anyone knows of a free weather service that can be interrogated by PHP for information such as current temperature for a range of cities around the world? www.wunderground.com has free banner 'stickers' you can use (i.e., graphics). They don't have an API for grabbing the information, but the schema they use is very easy to determine just by grabbing a few stickers here and there. Been a while since I messed with it, and the best detail I can give you is that the stickers included a common path, followed by COUNTRYCODE/STATE_PROVINCE_CODE/City_Name.gif, and that when you choose what type of sticker you want, that determines the path and the image size. -- Matthew Weier O'Phinney | WEBSITES: Webmaster and IT Specialist | http://www.garden.org National Gardening Association| http://www.kidsgardening.com 802-863-5251 x156 | http://nationalgardenmonth.org mailto:[EMAIL PROTECTED] | http://vermontbotanical.org -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Re: include()
* I. Gray [EMAIL PROTECTED]: Is there a big difference between me including a file by putting the url in the include() such as include(http://www.examplesite.com/examplefile.php) and putting the server path such as include(number/www.examplesite.com/public_html/examplefile.php) ? I want to get into good habits you see. I assume I have to use the first example when the file is on a different server. From a security standpoint, you usually only want to include and/or require files that are on your local system (your second example), unless under unusual circumstances (content sharing agreements with other sites, etc). Ideally, unless you want access to those scripts directly (i.e., http://www.examplesite.com/examplefile.php), you should place them somewhere in your include_path, which should be _outside_ the web server's document root. This prevents idle hacking attempts, and is generally considered a best practice. Additionally, using a network stream (which is what you're using when you specify 'http://') means that you've got additional performance overhead. Network streams are often more costly, resource wise, than file streams, and if the file truly is on a remote network, you then have to wait for that transaction to finish before continuing with your own processing. If you need to pull content off another server, but that content does not change often, you would be wise to have a background process running that pulls this content and caches it for use in your scripts. -- Matthew Weier O'Phinney | WEBSITES: Webmaster and IT Specialist | http://www.garden.org National Gardening Association| http://www.kidsgardening.com 802-863-5251 x156 | http://nationalgardenmonth.org mailto:[EMAIL PROTECTED] | http://vermontbotanical.org -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

You should mention that this has to do with PhpDocumentor... :-) The documentation for PhpDoc says that you can specify either 'object' or the classname of the object's type that is expected.

[PHP] Re: output buffering / output compression
* Paul Birnstihl [EMAIL PROTECTED]: I have recently set up a machine with PHP with both buffering and compression turned on. Some of the pages being served include up to 3MB of HTML. Can someone explain the benefit(s) of setting these ini directives to values (ie. larger than 4kb) rather than On ? I've played around with it as I thought it might speed things up by using a bigger buffer etc. but the only difference I noticed is a big jump in memory usage. The reason to set to a value is to set the buffer size -- and usually you do this to tune interaction between PHP and Apache and/or the underlying OS. You want to set it to a value that matches Apache's buffer size and/or the OS's network buffer size. If you don't know these, using the defaults is probably the best bet. -- Matthew Weier O'Phinney | WEBSITES: Webmaster and IT Specialist | http://www.garden.org National Gardening Association| http://www.kidsgardening.com 802-863-5251 x156 | http://nationalgardenmonth.org mailto:[EMAIL PROTECTED] | http://vermontbotanical.org -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Objects and Performance
* Greg Donald [EMAIL PROTECTED] : On 6/8/05, Greg Beaver [EMAIL PROTECTED] wrote: If you want to compare object methods versus functions, you should compare identical code inside a method to code inside a function. Greg's benchmarks compare two different ideological code structures. Quite honestly, the wrapping of mt_srand() inside a function or method does not satisfy the definition of good coding, object-oriented or otherwise. Functions/methods should be used to abstract common operations. mt_srand() already does this necessary abstraction, and putting a further wrapper around it makes no sense. I called mt_srand() inside the constructor, so it's only called once, same as the procedural version. This being an example of a class, it seems like the logical place to put it. I can remove it from both versions but it's not gonna change much as far as speed. If your code does simple operations on a few operands and returns a value, like our mt_srand() function, there is absolutely no point in making it more complicated. I agree. In the real world a given task will likely be more complicated, but that's not the point here. Actually, that is the point. What Chris was getting at is that usually you have a bit more going on in a function or method -- several operations, not just a wrapper for a single operation -- that the function/method call serves to abstract. So, calling a method that simply calls and returns a single php internal function call isn't going to give a good comparison; we already know that calling the function is faster. However, you could consider wrapping the functions inside a class and using them as static methods. There is little point in making classes to then only use the methods statically. You could just put all your similar functions in an include file and be done with it. Nothing more annoying than working on someone else's OO code and seeing Foo::bar() all over the place. Pointless. Unless you have several function libraries that were developed separately and *do* have the same function names. Where I work, for instance, at one point we had three function libraries, developed separately, that each had their own 'send' function, which worked fine until we tried to develop an application that mixed some functionality from the different libraries. Granted, we could have refactored and split out the common functionality from the libraries into a separate library, but we found it was much easier to wrap everything into classes and uses the class structure as a namespace. (We've since completely refactored and gone all OOP, but that's neither here nor there.) This would essentially give them a namespace that would allow any conflicts with other programmer's function names to be more easily resolved. If PHP needs namespaces then add them, last I heard the consensus was that it didn't. I've never needed them personally. It doesn't seem like enough justification to use objects just because you don't want to rename a few functions in the rare event you actually have a conflict. Seriously, how many times have you been working on a PHP project that was so big, with so many developers, that you bumped into each other with function names? Has yet to happen to me. That's *your* experience. You're going to keep seeing namespace discussions pop up whenever other people have experiences that indicate namespaces would help solve the issue. You're also going to have the issue pop up whenever you have developers from other languages start using PHP. I come from a perl background; I'd *love* to have namespaces in PHP... but I can use classes to emulate them fairly well. snip make the code readable and maintainable and it will cut down on bugs and work better than faster code. I always value efficient code over time to code. Doing more with less hardware should always be a programmer's first goal in my opinion. The overhead involved in bringing a web-based object into existence for the extremely short period of time it will live can never justify the 'maintainability' and 'readability' arguments I'm always hearing preached. I've never seen any OO PHP code that was easier to read or maintain for that matter. Again, your experience. I *have* seen OOP PHP that was easier to read and maintain. I've seen (and written) some perfectly horrendous procedural code that was a nightmare to read and maintain. You're right -- you should try to write efficient code. But sometimes you have to look at programmer efficiency as well -- if you're working for a client under a deadline, you don't always have that luxury. -- Matthew Weier O'Phinney | WEBSITES: Webmaster and IT Specialist | http://www.garden.org National Gardening Association| http://www.kidsgardening.com 802-863-5251 x156 | http://nationalgardenmonth.org mailto:[EMAIL PROTECTED] | http://vermontbotanical.org -- PHP

Jason Sweat covered this at php|Tropics, using SimpleTest as the unit testing framework. I use phpt unit tests (developed for testing php itself, and used by the PEAR project for regression tests). The principles are the same regardless of framework, however. The fundamental problem is: your code may depend on the results of a DB operation -- it's primary purpose may even be to perform a DB operation. While you can test the code, you still need to test whether or not your code can successfully perform the DB operation as well. A common problem I find is that I'm building SQL on the fly -- and that process may build shoddy SQL. It may be building exactly what I designed it to do, but the RDBMS will never be able to actually utilize the SQL I build.

[PHP] Re: PHP bug within multi. dimensional arrays?
* Merlin [EMAIL PROTECTED]:
Hi there,
I am outputting an multidim. array. That works fine, except one thing. The
first
letter of the value inside dimension 1 always gets printed.
For example:
I fill the arrays:
while ($row = mysql_fetch_object($result)){
$cat[$row-main_id][name] = $row-main_name;
$cat[$row-main_id][$row-sub_id][name] = $row-sub_name;
}
First off, if you're creating associative arrays, you should quote the
keys:
$cat[$row-main_id]['name'] = $row-main_name;
If you don't do so, PHP assumes you're using a constant value for the
key name.
Then I output them:
foreach ($cat AS $maincat){
echo $maincat[name].':';
Quote your keys!
foreach($maincat AS $subcat){
You do realize that the above will also loop over the index 'name',
right?...
echo $subcat[name].$br;
and since it does, the first element in that array is 'name', which
isn't an array, but a string. Since the 'name' constant isn't defined,
it will interpret that as 'true', or 1, and so it takes the first
character of that string.
}
echo $br;
}
Which does result in:
Europe:E
Germany
UK
North America:N
US
CA
As you can see I get the extra letters N and E. Is this an php error or did I
do
something wrong?
So, what you should probably do is create an additional layer in your
multi-dimensional array for the subcategories, and have it of the form
sub_id = sub_name:
$cat[$row-main_id]['subs'][$row-sub_id] = $row-sub_name;
Then loop over that:
foreach ($cat as $main_cat) {
echo $maincat['name'] . :\n;
foreach ($maincat['subs'] as $sub_id = $sub_name) {
echo $sub_name$br; // could also use $sub_id here if
// desired

This is very helpful and does work. However I did not understand it
completley.
What if I want to add another value, for example name2 or name3.
It looks like this example is limited to id and name.
Could I just add:
$cat[$row- main_id]['subs'][$row- sub_id] = $row- name2;
Guess not. Can you tell me how to add other fields to the array?
You should probably do some studying up on multidimensional and/or
nested arrays so you can get a better handle on this stuff.
If you need to be able to add multiple names for a sub_id, do it as an
array:
$cat[$row-main_id]['subs'][$row-sub_id][] = $row-name1;
$cat[$row-main_id]['subs'][$row-sub_id][] = $row-name2;
$cat[$row-main_id]['subs'][$row-sub_id][] = $row-name3;
However, this will break your loop above -- you'll need another layer of
looping added in:
foreach ($cat as $main_cat) {
echo $maincat['name'] . :\n;
foreach ($maincat['subs'] as $sub_id = $names) {
foreach ($names as $name) {
echo $name$br; // could also use $sub_id here if

}
}
}
Hope that helps.

$time2 = $timeend2 - $timestart2;
echo if-else took $time1 seconds\n;
echo ternary took $time2 seconds\n;
(Note: the above works in PHP5; you need to do some additional
contortions in PHP4 to get similar functionality with microtime.)
From my own benchmarks, it looks like the if-else is slightly faster.

[PHP] Re: stripping html tags
* Dotan Cohen [EMAIL PROTECTED]: I took this example from php.net, but can't figure out where I went wrong.

[PHP] Re: Unit testing ?
* mbneto [EMAIL PROTECTED]: I am trying the phpunit2 for unit testing but the examples found in the documentation are few and do not address, for example, tests when database access is involved. Perhaps this belongs to a more general question (i.e strategies for unit testing) so any urls, docs would be great. Jason Sweat covered this at php|Tropics, using SimpleTest as the unit testing framework. I use phpt unit tests (developed for testing php itself, and used by the PEAR project for regression tests). The principles are the same regardless of framework, however. The fundamental problem is: your code may depend on the results of a DB operation -- it's primary purpose may even be to perform a DB operation. While you can test the code, you still need to test whether or not your code can successfully perform the DB operation as well. A common problem I find is that I'm building SQL on the fly -- and that process may build shoddy SQL. It may be building exactly what I designed it to do, but the RDBMS will never be able to actually utilize the SQL I build. Tests can help catch these issues. Basically, when testing code that interacts with a database, you've got two basic strategies: (1) test against the DB, or (2) use mock objects. The latter is a tricky subject, as it assumes you're using a DB abstraction layer, and because you then have to mimic how that abstraction layer works. Basically, you end up doing a lot of code simply to test. Which brings us back to (1), test against the DB. The way to do this is to have some code that sets up and tears down a TEST database -- not the one with your live data. It should likely create and populate any tables you need, and then be able to tear them down again. The reason behind this is that you can then have a set of consistent data to test against -- once you run tests, chances are likely that you've altered the data. Each test you run should tear down the DB and then recreate and/or repopulate it. If you use the phpt unit tests, the place to do this is in your setup.php.inc file. I then create a file with the raw SQL for setting up and populating a test table, slurp it in with file_get_contents, and pass it on to the DB from within a function in that setup file. Then another function can truncate or delete all records from the tables utilized. The code within the test might then look like this: ?php include_once dirname(__FILE__) . '/setup.php.inc'; setupDb(); // do a test teardownDb(); setupDb(); // do another test teardownDb(); ? That's kind of a long-winded answer to your question, but it's not something you see a lot of information on. I hope that it helps. -- Matthew Weier O'Phinney | WEBSITES: Webmaster and IT Specialist | http://www.garden.org National Gardening Association| http://www.kidsgardening.com 802-863-5251 x156 | http://nationalgardenmonth.org mailto:[EMAIL PROTECTED] | http://vermontbotanical.org -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: Best way to use other objects within classes?
* Murray @ PlanetThoughtful [EMAIL PROTECTED]:
snip
(Note: my development environment is PHP 5.0.3, but the production
environment is 4.3.10. This is my first project built with 5.x local and
4.1.x remote, so if anyone with more experience spots any fatal flaws
where I'm using 5.x specific methods etc, I'd appreciate knowing about them)
snip
?
$db = connectMDB2(); // function that returns instantiated MDB2 object
$comments = new displayComments(); // class that performs displaying
of comments
$comments-set_db($db); // passing the MDB2 object to the class
$comments-doSomethingElse();
?
The displayComments() class might then look something like:
class displayComments{
private $db;
public function set_db($db){
$this-db = $db;
}
The above is the nut you need, and you're doing it right. As Greg
pointed out, you'll need to change that from 'private $db' to 'var $db'
as PHP4 doesn't have member visibility. However, you're correctly
passing by reference -- something required by PHP4 if you want to share
the same object amongst several classes. (In PHP5, objects are passed by
reference by default, and the above code will actually generate some
notices -- but since you're developing for PHP4, you can safely ignore
them).

Re: [PHP] PHP 5 Question about OO
* janbro [EMAIL PROTECTED] :
Okay, I see there is a workaround but nothing realy satisfying, but I'm
not hoing to complain, I'm hapy to have oo in PHP at all. I never worked
with __autoload so far, but I will give it a try and check it out
The best way to use autoload is with the auto_prepend_file configuration
directive. By adding the __autoload() function to a file that is
automatically prepended, you don't even have to think about it in your
scripts.
This kind of flexibility is nice -- you can have different prepend files
for different sites or different areas of the same site -- so that you
only have the funcationality accessible that you need right there. You
can also define your own naming schema -- which, admittedly is a dubious
advantage, but an advantage nonetheless.

Now my question, is it possible to skip that require/ include part? In
Java you don't need that, as class and file names are identical.
PHP doesn't have this luxury - people can call files whatever they
like. However, PHP5 does have a nice feature to deal with this. In your
class1 class, create a function called __autoload like this:
function __autoload($class_name) {
require_once $class_name . '.php';
}
In this case when you ask for a new class2 and you've not required it
before, it will automatically call __autoload with $class_name set to
'Class2', which then requires the class file according to the pattern
used in the function, in this case 'Class2.php'. Note that while PHP is
not case sensitive to class names, the file system you're on probably
is, so keep your case consistent throughout.
Docs are here: http://www.php.net/manual/en/language.oop5.autoload.php

[PHP] Re: Looking for a developer's weblog/cms system?
* Philip Hallstrom [EMAIL PROTECTED]: Over the years I've collected and done some things (tips, howtow, code snippets, etc.) that I think might be useful to others. Heck, I'd like to have them nicely organized too as now they are spread across machines, in email, etc. I'm thinking it might be nice to have an easy to use web-based cms system that I could post this sort of stuff too and assign it to a category and then let google index it. My problem is that there are hundreds of apps that do this. And a lot of them don't do what I need. A lot of them seem geared toward diary type applications, I want more of a this is my stuff which you might find useful. I can think of a couple of things: * A wiki. This would likely require some reformatting on your part, but even that could probably be scripted. The nice thing about a wiki is that you can either have it wide open so others may comment and contribute, or you can lock it down so only you or others you appoint may contribute. Additionally, each page gets its own URL, and most wikis worth their salt have search functionality. * A blog. Many blog packages allow you to add code snippets and will even hilight them for you; you usually also get search functionality and the possiblity of static URLs for content. Mostly I want something that has a decent look so I dont' have to think about that part. So, I'm asking you all for any recommendations you might have so I don't have to try dozens of these things out. I figure some of you must be doing the same thing and I'm hoping I can leverage your experience :-) I've used a variety of wikis; you just have to choose one and run with it. I'm not familiar with many blog packages, but do use Serendipity (http://www.s9y.org), and have played a little with Jaws (http://www.jaws-project.com/index.php); they have some nice features and are relatively easy to set up. Basically, I want a way to post things I think others might find useful. I'm not interested in user comments. I don't care about RSS. I would like to easily be able to mark things as code or type this at a shell prompt as well as link to entire source files, etc. If you'r interested in posting things I think others might find useful, why are you not interested in RSS? How will *others* know when you've posted something new? I find that RSS is a great tool for me to keep track of developers, projects, and other sundries. I rarely use my bookmarks anymore. Anyways -- the blog packages I've indicated above all utilize RSS, and may wikis do as well, so if you use one of the above solutions, you'll likely get that 'for free'. If all else fails... you're a PHP developer -- code your own! -- Matthew Weier O'Phinney | WEBSITES: Webmaster and IT Specialist | http://www.garden.org National Gardening Association| http://www.kidsgardening.com 802-863-5251 x156 | http://nationalgardenmonth.org mailto:[EMAIL PROTECTED] | http://vermontbotanical.org -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Re: Excellent language PHP5 is!
* Robert Meyer [EMAIL PROTECTED]:
There is one thing I hope is implemented in PHP soon. That is the ability
to pass by reference and receive the reference in variable parameter lists.
You can pass by reference to a function taking a variable number of
parameters, but func_get_arg() only returns the value and therefore, any
changes to that variable do not change the variable as seen by the caller.
Maybe a func_get_refarg() could be implemented.
Indeed, there's a comment on the func_get_arg() manual page to this very
effect.
One possibility is to wrap the reference into an array:
// in functioncall():
function functioncall() {
$args = func_get_arg(0);
$arg = $args[0]; // retrieving reference from array
$arg++;
}
$arg = 1;
functioncall(array($arg)); // passing an array with a ref
echo $arg;
I tested this, and it works. Requires a bit more work in the function,
but a little architecting could get it working.
Another possiblity is to pass associative arrays to your functions;
then, in your function, check for the existence of keys you need. The
beauty of this approach is that you don't have to muck about with the
func_get_arg() calls, you still get a variable number of arguments, and
you can easily pass references.
