actually: If the php directive register_globals is on, then $HTTP_REFERER will exist. Otherwise it will not. (or course that assumes a value exists at all).
Regardless of the register_globals setting, you can do: // Works since PHP 3 (forever)* print $HTTP_SERVER_VARS['HTTP_REFERER']; // Works since PHP 4.1.0 print $_SERVER['HTTP_REFERER']; Btw, $GLOBALS['HTTP_REFERER'] === $HTTP_REFERER. And lastly, since PHP 4.2.0 the register_globals directive defaults to off, which is what Jim was indirectly referring to. See also extract(). Regards, Philip Olson * For versions older then 4.0.3 see also the track_vars directive, it should be on.
