php: $referal

[Xavior]

I aint sure if there's such a php function.. tried searching in php.net but cant find it...
i have seen it somewhere in the net.. but forgotten the url..

It's a command that allows the script to know which site you came from, ie: referal page...

please help!

It is a global variable.

$_SERVER['HTTP_REFERER']
