_GET problem

I have been progging PHP for about 4 months now, and I'm working on a large project with alot of code. I havent updated PHP nor Apache in those 4 months, so I dicided to do that about a week ago. Now I'm having a nasty problem. with the old server I could do this:

When I called an file like this


and in that file



but with this new server, I have to add this:



As I have thousands of lines of code, I cant update my whole project.
What I'm hoping is that I forgot to enable a options somewhere in the PHP settings that enables automatic parsing of those variables! Please help me!

Change register_globals in the php.ini file. It's been set to off by default for security reasons. Change it to on.

Thanks alot. I'll slowly begin with adding al the _GETS because I read the sticky and the comments before the register_globals. But still thanks!
