Passing variables by means of a link.

pimpchimp

Hey all. I've read through the PHP manual and have gotten some skill at scripting so far, but I'm having a problem. I want to pass the value of a variable from a .php file to itself through the use of a link. That is, it'd be something like

http://www.whatever.com/hi.php?random=13

The problem I find, however, is that to make random a variable, in the file I'll already have to had declared $random, which overwrites incoming values, right?

So how do I curb this?

Thanks,

you access using the $GET array, i.e. $GET['random']

also, it is good to leave register_globals set to off.

So would that replace "$random = whatever;" ?
