[PHP] How to store data that doesn't change?
Hi, How do you people store data that doesn't change, an example of this would be the version number of your software. You might want to use it through out your program but how to you store it? As far as I can see there are several options to use this data. 1. Global Variable 2. Store it in a registry class 3. Store it in a named constant. 4. Use a function that will return the data (kind of like a regsitry class but it's not a class) Personally I don't like option 1 but what about the other options. Is any of them faster then the others. What other pros and cons are there. -- Peter van der Does GPG key: E77E8E98 IRC: Ganseki on irc.freenode.net Twitter: @petervanderdoes WordPress Plugin Developer Blog: http://blog.avirtualhome.com Forums: http://forums.avirtualhome.com Twitter: @avhsoftware -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Well, the only problem with going that route, is the one group is not
equally sized to the others. 18 is ok for a group in this instance,
but if it was a remainder of only 1 or 2, there would be an issue.
Which is where I come to looking for a the right method to break it
equally.
My take on it:
$Items=1252398;
$MaxInGroup=30;
for ($x=$MaxInGroup; $x1;$x--) {
$remainder=$Items % $x;
// Change 17 to the max amount allowed in the last group
if ($remainder == 0 || $remainder = 17) { //
$groups = (int) ($Items /$x)+1;
echo $groups.\n;
echo $remainder;
break;
}
}

Re: [PHP] Global Var Disappearing After Function

[PHP] Using ArrayObject
What is the advantage of using ArrayObject to build a Registry class? -- Peter van der Does GPG key: E77E8E98 IRC: Ganseki on irc.freenode.net Twitter: @petervanderdoes WordPress Plugin Developer Blog: http://blog.avirtualhome.com Forums: http://forums.avirtualhome.com Twitter: @avhsoftware -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Registry class question.
Hi,
I've build a registry class to store settings I need to use in several
other classes.
Currently I've set it up with a static array in the registry class and
using two methods to access the settings and values
storeSetting($key,$value) {
$this-_settings[$key] = $value;
}
getSetting($key) {
return $this-_settings[$key];
}
The question is what the pros and cons are compared to setting a new
property with the value, like:
storeSetting($key,$value) {
$this-$key = $value;
}
and then instead of calling getSetting, you just use
$this-Registry-property

There are several options to stop spammers, although none of them will
completely eliminate all spam. For a forum I prefer the .htaccess
method.
There is a website dedicated to keeping track of forum spammers,
http://stopforumspam.com and depending on your forum you could add an
anti-spam mod that will query their database. On the site they have
mods for phpbb, vBulletin and SMF.
I wrote a Python script that uses a Python Library that's also posted
on their site. The Python program basically use an Apache log file for
the IP's checks them at Stop Forum Spam and adds spam IP in
the .htaccess file. I have it set up in cron to run daily.
For a little bit more detailed description and the program itself:

It is not overwhleming, but about 5 a month. What is the best way to stop this. Thanks Gary One of the things you could check is if they do direct posting. What I mean by that if that sometimes a POST URL only is send. They figured out the fields you have in your form and directly send a POST with the appropriate fields. You could check this in the webserver logs. Just look for the IP and see if it only has a POST URL. If this is the case you could implement a nonce on your form and check it during the processing of the post. A second idea is to check the IP of the visitor during the POST process, with something like stopforumspam or project honey pot.

If so, just download something you are interested in, maybe WordPress if you blog, with some plugins as those are most likely easier to read, and look at the programs and try figuring out why things are working they way they work. I can't really remember how I started but I believe it was with Postnuke a long time ago. I looked at the code, try to help fix bugs.

[PHP] PHP class question
I have the following situation.
I wrote some software and split it up into functionality:
class core {
function go{
}
}
class A extends core {
// PHP4 constructor
function A {
$this-go();
}
}
class B extends core {
}
In core I define functions and variables that are to be used
through out my program and to address those functions/variables I just
use $this- .
Now I ran into a situation where class A needs to be extended with
another class. This is not my choice, it's part of a framework I have
to use.
Currently I solved this by doing this:
class A extends framework_class {
$var core;
// PHP4 constructor
function A {
$this-core = new core();
$this-core-go();
}
}
The question I have, is this a good solution, is it the only solution
or are there different ways to tackle this?
As you might see it needs to run in PHP4.

[PHP] Multiple return statements in a function.
I tend to put my return value in a variable and at the end of the
function I have 1 return statement.
I have seen others doing returns in the middle of the function.
Example how I do it:
function check($a) {
$return='';
if ( is_array( $a ) ) {
$return='Array';
} else {
$return='Not Array';
}
return $return;
}
Example of the other method:
function check($a) {
if ( is_array( $a ) ) {
return ('Array');
} else {
return ('Not Array');
}
}
What is your take? And is there any benefit to either method?

If this is in one file, as I assume it is, here's what is happening:

You should check if information is send and if it's not don't process
the $_POST cause the $_POST is empty.
