Hi all:

PHP 5.2 has some really very useful features for web developers

 . Ability to Track and monitor PHP memory. 
   Instead of malloc( ) / free( ), 
   we have got how much am I using / how much I left with.
   This is a first for any scripting language that I know of. Wow !

 . Input validation and filtering as the HTTP stream is processed.
   
 . new JavaScript Object Notation (JSON) extension, 
   which provides PHP developers with better support for Ajax applications.

There are two interesting articles posted by Tracy Peterson.
