fun with register_globals

Hi folks, I might be late to the game with these questions, but I've just been bit by the register_globals=off situation. I'm trying to figure out the scope of what I need to change to accomodate register_globals=off, and I need some help. Looking around php.net, for example: 'If register_globals = on, the url http://www.example.com/test.php?id=3 will produce $id.' I can only assume with register globals being set to off, the reverse of this would be true. If so, how do I get the value of id in that case? Kelly
