Capturing Variables

[delasare]

First off, I'm fairly new to PHP programming, so there may be some easy
solution to this.

I have several forms that collect and pass variables to another page that a inserts them to a mySQL database. Everything seemed to be working fine and then yesterday they seemed to stop working. Every form I submit gives me an Undefined Variable error message. The only thing we have done different in the last week is an upgrade to the PHP module on our web server. Could that be the problem?

I've tried writing new code just to check if the variable was there with no luck.

Any help or ideas would be greatly apprciated?

I think I've solved my own problem. The Register Globals directive in our ini file was set to off, so I turned it on. Everything seems to be working again. Now can anyone tell me if it is good or bad to have this turned on. A few things I've read suggest that it is better to specifically state $GET and $POST.

Any thoughts?

The advantage to use $GET and $POST is that if you have another variable that has the same name as a form variable, the form variable will lost its value to be remplaced with the new value... and it is more secure(well, that's what PHP says). I always use them.
