it's $_SERVER['HTTP_REFERER'] and the manual

http://www.php.net/manual/en/reserved.variables.php

has some info you should take into account :)

'HTTP_REFERER'

. The address of the page (if any) which referred the user agent to
the current page. This is set by the user agent. Not all user
agents will set this, and some provide the ability to modify
HTTP_REFERER as a feature. In short, it cannot really be trusted.
