Going from PHP3 -> 4

[Anon]

Everyone :

It's been over a year since I used PHP. At that time I used version 3.x. I'm starting to get back into PHP for a new project and the client wants to use PHP 4.x What are the main differences between the two versions? What new features should I concentrate on learning?

Thanks for the help,
Dale Williams

As far as I know, session feature is supported only in PHP 4.
Probably you should look into register_globals issue. In PHP 4, it is turned off by default. So, instead of accessing posted variable using $var, you have to use $HTTP_POST_VARS["var"].

Detail information should be provided at PHP Documentation accessible from http://www.php.net
