PHP globals aren't really globals

I've been programming in C all my life, and now I just started developing in PHP and I'm really enjoying it, it has all the missing improvements that C needed to be more user-likely. But one thin I can't get, how can PHP call a variabel global, if it isn't global. A global var, is a var defined outside all functions and it's available to all and altered by all, without having to redefine or call the var again. In PHP, for a var to be global you have to add a 'global $var' inside the function u want to use it. THis is not nice, what about if u have a form with 50 fields and want a function to validate all of them, u have to pass them all to the function or build a little piece of code to make all th $GLOBALS local right? Is this really the idea of global vars? . [ Christian Dechery ] . Webdeveloper @ Tá Na Mesa! . Listmaster @ Gaita-L . http://www.tanamesa.com.br
