RE: [PHP] session management
There's a sessions tutorial on phpfreaks.com that outlines the basics of using sessions. I'm not 100% sure what you mean when you say you don't want to do url rewriting. Without either cookies or passing a url param, there is no way to determine if the request comes from someone who has an active session. As for session classes, there are many. Try the usual places... google, sourceforge, freshmeat, phpclasses etc. -Original Message- From: ajay [mailto:[EMAIL PROTECTED] Sent: Thursday, January 29, 2004 9:56 PM To: [EMAIL PROTECTED] Subject: Re: [PHP] session management hi! well i do have a MySQL database.

[PHP] Am I missing Something
Greetings all, I am running version 4.3.4 of PHP. Fairly recently. I am trying to call a pretty basic programming tool. Maybe I am just really tired, or something but I am not getting what is going on. Is there something I am missing. I am pulling a SQL call on a date to get the month. I am using Date_format and the %c to get the Month in numeric format. The I plug it into a variable and my intention is to call it as the index of an array. Nothing prints. When I turn on all notices I get a notice that it is an undefined index. What the heck is going on??

[PHP] Why are my style sheets all listed on one line?
I'm still fairly new to PHP, so there may be a simple fix for my
relatively trivial complaint.
I'm using an included page as a head section. It works fine, except that
when preview a page and view the source, all the style sheets are
displayed on one long line, like this:
/scriptlink href=../../css/ref.css rel=stylesheet
type=text/csslink href=../../css/na/a1.css rel=stylesheet
type=text/css /link href=.css rel=stylesheet type=text/css
/link href=../../css/nations.css rel=alternate stylesheet
type=text/css title=Nations /
It looks like they won't scroll across THIS page, so here's a more clear
example:
stylesheet1stylesheet2stylesheet3stylesheet4
What I want is a normal style sheet display, like this:
stylesheet1
stylesheet2
stylesheet3
stylesheet4
Do you know what causes this and if there's a fix? I posted some code
from the head section and main page below.

Thanks for the tip. However, I must be doing something wrong. \n didn't
work, so I searched Google for PHP + new line and found a page that
said you have to use \r\n if you're working on a Windows platform. But
that doesn't seem to work, either. (If you do use a special new line for
a Windows computer, then publish your website to a Linux server, will
that cause problems?)
Do I need to modify the new line code because my echo statements are
enclosed in single quotes (' '), rather than double quotes ( )?

newline-character should be inside double quotes (\n).
For example:
instead of:
echo 'link href=' . $periods . 'css/nations.css rel=alternate
stylesheet type=text/css title=Nations /\r\n';
use:

I believe the problem is with the security permission on ... somewhere, since I've been doing the same setup in several machines and it works fine (not in this network).

[PHP] OOP methodology
This is a long one - I'm trying to get to grips with my understanding of
OOP.
I'm not sure that I understand object oriented programming as well as I
could to benefit from using it in PHP. Although I've used it to produce
working applications, of the few objects I've produced nearly all have
carried too much weight and functionality (one object for both HTML
generation and DB interaction etc) and several have been extensions of the
others.
I was hoping someone might be able to check my logic.
One of the main functions of the application I'm working on at the moment,
my first use of OOP in PHP, is to iterate through a hierarchy of retail
outlets and extract information from a database based on each location in
the hierarchy. A template SQL statement is parsed and parts are replaced
with information from the hierarchy. This query is then executed, and the
results are placed in a table within a static HTML file stored in a
directory structure which mirrors the structure of the retail outlet
hierarchy. I've done it this way because the traffic to the site is
expected to be high and the information changes infrequently, so static
pages will ensure good performance.
The way I've written the application isn't up to much IMO, using objects in
a primitive way akin to a PC newbie using the CD ROM drive as a coffee cup
holder - ie. does the job but it's not quite how it was intended to be
used.
I've got one big object (treeMapper) that does everything, which includes
(over and above the database functions, file input and output, HTML
generation and string formatting). It has two main methods. Process() and
taskMaster(). The first method iterates one unit through the hierarchy and
then calls taskMaster() which takes values Process() has changed in the
object and uses them to query the database and to format the results into
an HTML table and output to a file (as described above).
In the code for the class, taskmaster() is empty. When I want to use the
class, I create a new class which extends treeMapper and then overrides the
taskMaster function. In this way I get an object which I can reuse for any
report which needs to be made for every store. It works and it's fast, but
this method seems really WRONG!
I started developing this six months ago as a first project in OOP in PHP,
and am starting to see it's limitations - for instance, I need to use the
DB functions for other small tasks on the site, which involves
instantiating a new treeMapper (which is highly inefficient as I won't need
the other 20 methods.). I've also got some handy string manipulation
routines which can't be used without instantiating a treeMapper. So I want
to break it up into smaller chunks, smaller objects which can talk to each
other.
From what I've read, I think I should be using an iterator pattern to
design an object which JUST does the iteration, a database object which
JUST does queries from the database, another iterator object which JUST
does iteration through database results and another object which draws
graphs based on results from the database.
My question is (I know you've been waiting) how best to connect up these
objects, as I only really need one instance of each object for my
application. PHP 5 objects seem easier to deal with (none of this
incomprehensible notation) and I want to know whether the following is a
good way of doing it and how other people might go about this.
class dbObj
{
var $results;
function dbObj()
{//set up DB con}
function execQuery()
{//ODBC query exec - results put in $this-results}
}
class iterator
{
var $currentPos
function iterator()
{//loads data into iterator}
function reset()
{//Resets pointer}
function next()
{//steps forward one item, changes $this-currentPos to whatever.}
}
class HTMLGenerator
{
function HTMLGenerator($dbObj, $iterator)
{
$this-dbObj = $dbObj;
$this-iterator = $iterator;
}
function MakeHTML()
{// as you'd expect.
// refers to $dbObj and $iterator (objects passed by reference in
// PHP 5)
// $iterator-currentPos used to parse SQL query
// eg. $dbObj-execQuery(select...);
// eg. $dbObj-results used to make HTML;
// }
function outputToFile()
{//Saves to File}
}
The main application would then do this:
$q = new dbObj;
$x = new iterator;
$y = new HTMLGenerator($q, $x)
while ($x-next())
{
$y-MakeHTML();
$y-outputToFile();
}
Anyone got any thoughts about whether this is a good way to do it? I was
wondering whether instantiating objects should be done within other objects
that need them - if this can be done - but I would only do that in cases
where (for instance) an HTMLGenerator object is instantiated without any
parameters, in which case some logic could be added to do this.
Thanks!
Chris

Re: [PHP] PHP timeout
Mario, Please don't reply to a message when you want to ask a question compose a new thread instead. Anyway from what you have described it sounds like you have a firewall that's blocking the mysql port. Somefirewalls just drop the packets instead of denying the connection. That way the script just hangs an eternit waiting for a packet that never arrives. Try stopping your firewall completely .

By the way, the test

It has exactly the same outcome, but is both more readable (if you've named
your variables suitably) and more efficient (since you've saved the
redundant comparison operation).

Re: [PHP] OOP methodology
Hi Chris, Sounds to me like you are pretty much on the right track bearing in mind that PHP is not the bes language to learn OOP. Even your taskmanager sounds good, i wouldn't bother with reading up on design patterns just yet. They are indeed very important and you should definitely study them, however having spent an year or more doing OOP helps you understand them better. (others will disagree). Don't worry about classes become too big either if all the code belongs in one class it can't be helped. If you look at a fairly large java program you will find classes that range from 20-30 lines to 2000+ lines.

[PHP] PHP Style Switchers - Recommendations?
I've been using JavaScript style switchers combined with alternate style sheets, allowing users to control the appearance of my web pages. However, I recently read that you can make style switchers with PHP - which are allegedly superior to JavaScript style sheets. Then I found a PHP style switcher at http://www.contrastsweb.com/switcher/v2/example.php that has an added advantage; you can apparently choose several style sheets independently of one another. For example, you can change the background color, then change the font. I'm working on some complex tables that I'd like to control with such a multi-style switcher. Suppose I have five style sheets, named One, Two, Thtee, Four and Five. I'd like to set it up so that a visitor can view the page with any one of these style sheets, or with a combination thereof, such as One, Three and Four or Four and Five. At any rate, I couldn't get the PHP style switcher above to work. (See, also, http://www.contrastsweb.com/switcher/v2/) I just wondered if anyone on this list has worked with PHP style switchers and can recommend other tutorials or different strategies. Thanks. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] OOP methodology
Here is my advice, check out the pear code, it will help you dearly get the
grips of how to setup classes. IMHO i feel pear is a standard, i use most of
the standard but i dont particularly write classes for pear but structure it
similar, but am thinking of porting my error code around pear. Classes are
purely packages which are reusable within projects, try not to get simple
functions with complete classes mixed up, it may not be needed to make a
class at all. Hope this helps.

Subject: [PHP] OOP methodology
This is a long one - I'm trying to get to grips with my understanding of
OOP.
I'm not sure that I understand object oriented programming as well as I
could to benefit from using it in PHP. Although I've used it to produce
working applications, of the few objects I've produced nearly all have
carried too much weight and functionality (one object for both HTML
generation and DB interaction etc) and several have been extensions of the
others.
I was hoping someone might be able to check my logic.
One of the main functions of the application I'm working on at the moment,
my first use of OOP in PHP, is to iterate through a hierarchy of retail
outlets and extract information from a database based on each location in
the hierarchy. A template SQL statement is parsed and parts are replaced
with information from the hierarchy. This query is then executed, and the
results are placed in a table within a static HTML file stored in a
directory structure which mirrors the structure of the retail outlet
hierarchy. I've done it this way because the traffic to the site is
expected to be high and the information changes infrequently, so static
pages will ensure good performance.
The way I've written the application isn't up to much IMO, using objects in
a primitive way akin to a PC newbie using the CD ROM drive as a coffee cup
holder - ie. does the job but it's not quite how it was intended to be
used.
I've got one big object (treeMapper) that does everything, which includes
(over and above the database functions, file input and output, HTML
generation and string formatting). It has two main methods. Process() and
taskMaster(). The first method iterates one unit through the hierarchy and
then calls taskMaster() which takes values Process() has changed in the
object and uses them to query the database and to format the results into
an HTML table and output to a file (as described above).
In the code for the class, taskmaster() is empty. When I want to use the
class, I create a new class which extends treeMapper and then overrides the
taskMaster function. In this way I get an object which I can reuse for any
report which needs to be made for every store. It works and it's fast, but
this method seems really WRONG!
I started developing this six months ago as a first project in OOP in PHP,
and am starting to see it's limitations - for instance, I need to use the
DB functions for other small tasks on the site, which involves
instantiating a new treeMapper (which is highly inefficient as I won't need
the other 20 methods.). I've also got some handy string manipulation
routines which can't be used without instantiating a treeMapper. So I want
to break it up into smaller chunks, smaller objects which can talk to each
other.
From what I've read, I think I should be using an iterator pattern to
design an object which JUST does the iteration, a database object which
JUST does queries from the database, another iterator object which JUST
does iteration through database results and another object which draws
graphs based on results from the database.
My question is (I know you've been waiting) how best to connect up these
objects, as I only really need one instance of each object for my
application. PHP 5 objects seem easier to deal with (none of this
incomprehensible notation) and I want to know whether the following is a
good way of doing it and how other people might go about this.
class dbObj
{
var $results;
function dbObj()
{//set up DB con}
function execQuery()
{//ODBC query exec - results put in $this-results}
}
class iterator
{
var $currentPos
function iterator()
{//loads data into iterator}
function reset()
{//Resets pointer}
function next()
{//steps forward one item, changes $this-currentPos to whatever.}
}
class HTMLGenerator
{
function HTMLGenerator($dbObj, $iterator)
{
$this-dbObj = $dbObj;
$this-iterator = $iterator;
}
function MakeHTML()
{// as you'd expect.
// refers to $dbObj and $iterator (objects passed by reference in
// PHP 5)
// $iterator-currentPos used to parse SQL query
// eg. $dbObj-execQuery(select...);
// eg. $dbObj-results used to make HTML;
// }
function outputToFile()
{//Saves to File}
}

Yes, but you need to force PHP to re-evaluate the string you retrieve from
the database -- normally, PHP just uses values retrieved at runtime as-is
and doesn't do any special interpretation on them.
The function you need to do this is eval() (http://www.php.net/eval), and
one possible way of using it to achieve your desired result is (off the top
of my head, untested):
eval('echo blah {$row[\'thecolumn\']} blah;');

What you need to understand is that the string parsing for variables
only happens when the string is actually in your script. When you
dynamically create a string (or get it from a DB) it's just a string of
characters in memory and is *not* parsed.
To do something like this, you would have to use one of a few things.
The first would be to use some kind of search and replace to replace
those variables with what you really want.
$text = str_replace('$name', $name, $text);
That's fairly simple and could even be done for multiple variables.
foreach(array('name', 'price') as $varName) {
//yes, the $$ is correct
$text = str_replace('$'.$varName, $$varName, $text);
}
You could also use a regular expression if you *really* wanted to, but
what's above is easier.

Indeed. The following script had my machine happily swapping like crazy
at 320,000 array items (each being 1k, task manager showed 640meg total
memory in use on this development machine with 512meg RAM running WinXP).
?php
while (@ob_end_flush());
$data = Array();
while (true)
{
$data[] = str_repeat('#', 1024);
print count($data).\n;
}
?
To the OP, why do you need to store all the items in memory at the same
time? Can't you read some, process them then read the next lot, process
them, read the next lot etc?
No I couldn't because we have to use 1,6 Mio values direktly. If we read
them each for each it will take a lot of time.
We discover we can use an Array with 2.000.000 Values - if higher the server
(Intel 1 GHz, 32 Bit, 1 GB RAM) gives up.
Ciao,
Sandro

Re: [PHP] Am I missing Something
You have: select date_format('%c', date_column)
You need: select date_format('%c', date_column) AS date_column
Else the column name in the result is date_format('%c', date_column).

I am pulling a SQL call on a date to get the month. I am using

Re: [PHP] OT, Maybe: Question Re: Apache/Macintosh Platform
What you have is fine, but I think (I don't do it that way) this means each user will have completely separate code. That might be A Good Thing, or you might be the only user anyway. An alternative is to use /Library/WebServer/Documents/ Any pages placed there can be called with either 127.0.0.1/yourpage.php or localhost/yourpage.php (127.0.0.1 and localhost do not appear to be completely interchangeable; I've found places where one works and the other doesn't). An advantage of using /Library/WebServer/Documents/ is that you can set up virtual hosts in httpd.conf (/private/etc/httpd/httpd.conf). I have several development sites set up - www.xxx.dev, www.yyy.dev etc - paralleling the live sites. I can switch between development sites as quickly as between live sites.

there is one pit fall on this method that I run into sometimes. If your

The END; must be the first text on the line, so it has to be like this,

What you need to understand is that the string parsing for variables
only happens when the string is actually in your script. When you
dynamically create a string (or get it from a DB) it's just a string of
characters in memory and is *not* parsed.
To do something like this, you would have to use one of a few things.
The first would be to use some kind of search and replace to replace
those variables with what you really want.
$text = str_replace('$name', $name, $text);
That's fairly simple and could even be done for multiple variables.
foreach(array('name', 'price') as $varName) {
//yes, the $$ is correct
$text = str_replace('$'.$varName, $$varName, $text);
}
You could also use a regular expression if you *really* wanted to, but
what's above is easier.

Well, I would have mentioned eval(), but you have to put PHP code in
there instead of just strings. For example, Hello $name. would have to
become.
'return Hello $name.';
or
'return \'Hello \'.$name.\'.\'';
If you eval a string with Hello $name. in it, you will get a parse
error. For readability, I would think that using str_replace to replace
specific variables would be better.
Actually, it would be even better if you used a templating system to do
this kind of thing, such as Smarty. That way you don't have to worry
about variable replacement, but your strings can still be easily edited.

On a pseudo-related topic: what should you use to find the absolute path

For example, I'm writing an application that has a function library in
'app/lib/'. From any file in the application, at any directory level, I
want to be able to include specific files from the library.
What's the best way to find '/absolute/path/from/root/' from

Since the path you get from 'DOCUMENT_ROOT' isn't necessarily where the
executed file is (e.g., user directories), should that be avoided for
this type of task?
Not sure if this will help either, but this is what I use to determine
where I'm at in scripts I write.

$this-CONF['path'] = dirname($_SERVER['PATH_TRANSLATED']);
//Determine protocol of web pages

else

//HTML address of this program

if($dir_name == '\\')
{ $dir_name = ''; }
$this-CONF['html'] = $this-CONF['protocol'] .
$_SERVER['SERVER_NAME'] . $dir_name;
//Determine web address of current page
$this-CONF['current_page'] = $this-CONF['protocol'] .
$_SERVER['SERVER_NAME'] . $_SERVER['SCRIPT_NAME'];
Then, if all of my methods, I use $this-CONF['path'] to include files
relative to the file system and $this-CONF['html'] to include files
relative to the HTML root.
//Include a library file
include($this-CONF['path'] . '/includes/db.inc');
//Path to image

[PHP] Re: OOP methodology
Wow, that's a lot of stuff in one class. Personally, I've started using the MVC (Model, View, Controller) architecture. Basically what it does is seperates Data logic from Display logic and Control logic. Here's how I've been using it. Model: Holds and deals with all data for the program, such as database connections / queries, session data, data consistency. I am currently using classes which use PEAR DB_DataObject for DB connections, querying, and data storage. View: Deals with displaying of data from model. ONLY does displaying, no processing. Very minimal logic only associated with outputting. Currently, I am using Smarty entirely for the view. Little no no PHP code, only Smarty. The View in this case is just a smarty template file. Controller: Handles requests from the browser. Instantiates Model and View, calls functions in Model to alter its state (updating from $_REQUEST vars, for instance). Chooses a view and then tells the view to display. For me, this is all home-grown PHP. This architecture can be much more complicated in, say, a C++ program, but the Server/Client pattern built into web programs makes it much more simple. The reason that I use this particular architecture is that it factors all of the pieces of your program very nicely. Later, if you do things right, you can use a single screen from one program in another with minimal editing.

[PHP] exec cURL to pass custom MIME headers
Hi,
Normally I wouldn't do this but the cURL list seems to be in severe
hibernation, ie. no activity. I'm in a bit of a jam w/ this and so here
goes
How do I get cURL to pass headers properly? It is ignoring my -H
headers and sending its own default or whatever set of headers. One
example, it submits as x-www-urlencoded-form or whatever but I want it
to just send -H my headers!. Can anyone point me in the right
direction? I know I probably just need to change something simple
here.. see below:
?
$mime_headers=POST /AUTHORIZE HTTP/1.0\nMIME-Version:
1.0\nContent-type: application/X1;
$xml_content={some XML - use your imagination here};
exec(/usr/local/bin/curl -m 120 -H \$mime_headers\ -d \$xml_content\
$merchant_URL:$merchant_PORT -L, $return_message_array, $return_number);
?
So any ideas!?!???
Also, is cURL abandoned or what? I thought their list would be active
to at least some degree.
Thanks in advance for any help.

(for this example i wrote only jpg, i will be having png and gif too)
Depends if the images are freely accessible to anyone or you want to
protect them so they must be served by php script.
If the former I like to keep the original name that usualy has some
meaning. If image of that name already exists (e.g. john.jpg), I append
2, 3, 4 etc. (e.g. john2.jpg). You need to lock the script somehow so it
does not run into race condition, I use mysql GET_LOCK function for
this. So the whole process looks like:
/* wait 30 seconds to get the lock, then the function fails and returns
0, you should take care of this error */
SELECT GET_LOCK('upload_image', 30);
$image_name = $_FILES['name']['fileinput'];
$i = 2;
while(file_exists('userimages/'.$image_name)) {
$image_name = // append $i here
}
move_uploaded_file($_FILES['tmp_name']['fileinput'],
'userimages/'.$image_name);
// update database
// release lock
SELECT RELEASE_LOCK('upload_image');
If you serve the files by a php script, it does not matter what name you
give the file on the filesystem, you can use uniqid() for example. Store
the real name in the database, this gives you the advatage that you can
have the same names. Still you should use the above lock and loop to
make sure the script won't overwrite another file.

Re: [PHP] Size of Arrays
Should anyone be planning experiments or projects with large arrays, use a for() loop instead of a foreach() loop when working with your array. And be sure to count the array, stick that result into a variable, then compare against the variable instead of running the count() again. On huge arrays (hundreds of thousands of elements, three dimensions, several megabytes) the performance impact is huge! The downside is you'll probably have to use numeric keys instead of associative, but for big arrays, numeric keys will probably also keep more memory free and improve performance a bit.

Hey all, I'm sure you must have visited sites where articles on a page have links to place that explain what that word means.. eg: This is an article about a computer programming language called php which is taking web development to a different. in the above snip of the article computer programming would be a link to some page that explains that, php could point to php.net or maybe have a dhtml popup that explains what P.H.P stands for etc etc Doing the above in a static .htm page is pretty easy, but doing this on a dynamically generated page is a bit hard.. as first you get the content from the DB, search for the words that match your (probably) array of link words, replace the word with the code to generate a link or dhtml popup Thats putting it in the rawest sense...anybody know of any class, free piece of code, example functioning code etc that does this?

RE: [PHP] Logging on to a web based application
I use a DB table to manage my users, I do not have to worry about locking it down to one user, however one thought is to track the user into a temporary DB, if the user name is there and the sessionID does NOT match the one in the DB, then the user is not granted permission to access the programs. If they have logged out, then the logout page will go in and delete the user from the DB field. As each page is loaded it checks the DB against the user's cached data. If there is an issue, the DB is treated as correct and the user is dropped. Once that happens a few times to someone logged into a critical app and they lose data (it should check the data before storing information) then that will essentially for the users to have their own user/pw combo.

[/snip] Obviously. :) I'd be curious as to how many cam to PHP from a programming background? Likewise, how many start with PHP and go on to other languages? And what those languages are either direction? Here's my progression: BASIC - Turbo Pascal - C - C++ - PHP. Yes, I came to PHP from C++, having learned OO in C++. But honestly, I've learned a lot more good OO practices in PHP than I ever did in C++. -- paperCrane Justin Patrin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I am running version 4.3.4 of PHP.
Fairly recently. I am trying to call a pretty basic programming tool.
Maybe I am just really tired, or something but I am not getting what is
going on.
Is there something I am missing.
I am pulling a SQL call on a date to get the month. I am using
Date_format and the %c to get the Month in numeric format.
The I plug it into a variable and my intention is to call it as the index
of an array.
Nothing prints.
When I turn on all notices I get a notice that it is an undefined index.
What the heck is going on??
Sorry, left my mind reading helmet at home today. How about sharing some code.
$sql = SELECT CONCAT(DATE_FORMAT(initiation_date, '%b '), initiation_day,
',' , DATE_FORMAT(initiation_date, ' %Y')) AS weekend,
DATE_FORMAT(initiation_date, '%c ') AS month, initiation_day FROM center,
initiation WHERE initiation_date = CURRENT_DATE AND initiation_center =
center_id AND center_id = $g_cen ORDER BY initiation_date ASC;
$wkends = new MySQL($sql);
while ( $rec = $wkends - fetchRow () ) {
list($sday, $eday) = explode('_', $rec['initiation_day']);
if ( $sday == '29' || $sday == '30' || $sday == '31' ) {
$somevalue = $rec[1];
echo $g_dates .= $somarray[$somevalue];
}
}
Through testing, if I echo out $rec[1] I get to correct value (3)
If I echo out $somevalue I get the correct value (3)
However $somarray[$somevalue] prints out nothing.
Again if I display all notices then what I get is that there is an
undefined index on the lines that has
echo $g_dates .= $somarray[$somevalue];
And $somarray[ has more than four values.
