If you encounter session error on PHP 4.4.x, especially when you're porting scripts written from earlier PHP release (i.e PHP 4.1.x, 4.2.x) when handling sessions, chances are that you are using the deprecated session_register() function.
Solution: Replace session_register function with $_SESSION variable instead.
This will make your scripts upward-compatible with PHP installations that disabled register globals and eliminate those weird session errors message

If you're porting your PHP4 scripts that uses DOM-XML for xml-parsing to PHP5, then you might have stumbled into this particular problem, PHP5 has no DOM-XML extension.
This is because PHP 5 has a new integrated DOM functions which replaces PHP4 dom-xml equivalent.
However you don't need to do a complete rewrite in order to make your DOM-XML PHP 4 scripts work with PHP 5. All you need to do is to include a fix from http://alexandre.alapetite.net website.
First, download domxml.phps, then include it in your php scripts
PHP:
-
require('domxml.phps');
-
-
// the rest of your script that uses dom-xml goes here...
After that your PHP4 script is able to work normally in PHP5 environment :)

Here's a simple function to validate email in your PHP scripts.
To use it just call isValidateAddress("email@example.com"). The function returns 'true' if the email is valid and 'false' otherwise.
PHP:
-
<?php function isValidAddress( $email, $check = false )
-
{

Yesterday I had to look for a simple Java XML-RPC library in a simple proof of concept application.
Plainly speaking, I'm going to demonstrate XML-RPC concept to a bunch of friends who is unfamiliar with programming languages other than Java (but they are not 1337 programmers either!)
I'm looking for a simple library which isn't bloated with functionality and easy to use. After much surfing, I found Redstone XML-RPC Library.
