does referer work?

[abman]

hi, i'm basically trying to get the URL address of the last website visited before visiting my website, i've done some research and found the variables

$HTTP_REFERER
$_SERVER["HTTP_REFERER"]
$HTTP_SERVER_VARS["HTTP_REFERER"]
$HTTP_ENV_VARS["HTTP_REFERER"]

was the answer, when i tested it. Apparently they didnt work.... 😕 Any suggestions why this is happening? Am i missing something?...Or any other sulotions? Thanks!

That's about the best you're going to have: if your site was visited via a link, the client may add an HTTP-REFERER field to the request. It's not obliged to though, and even if it did, it might be bogus. If the address to your site was obtained by the client some other way (e.g., someone typed it into the address bar of their browser) then HTTP-REFERER will be blank in that situation because there wouldn't be a referrer.

But I don't rule out completely the possibility that your server isn't passing the value to PHP.
