Re: Using HTTP Referer

The variable name is just $HTTP_REFERER. Some others are: $HTTP_USER_AGENT, $REMOTE_ADDR, $REMOTE_HOST, $QUERY_STRING, and $PATH_INFO. There's more which you can find by looping through the globals array: foreach ($GLOBALS as $key=>$value) { print "\$GLOBALS[\"$key\"] == $value<br>\n"; } Hope this helps!
