is it possible with php to detect the site that referred the user to the current site, i.e. if site X was found through a google search, php can detect it?

[aldo]

You can use www.google-analytics.com put the code on your site and it will show you where you get refered from, such as Yahoo! Google Search and the keywords used, and other websites. It is very useful. I am sure though you could use PHP to determine that but it would be easier with a Stats tracker, Such as I said, because a PHP script that your asking about may be resource intensive

$_SERVER[HTTP_REFERER] Contains what you seek.

[aldo]

Actually $_SERVER['HTTP_REFERER'] is what you seek

It works either way.

holy guac! that works exactly what what i wanted lol!

thanks~

[bind]

Please note NEVER to trust the $_SERVER['HTTP_REFERRER'] return value ... it can be completely blocked and even forged in the headers from the client side. It should be used for information purposes only.

[inp o҉rtb]

It works either way.

However, the quoted value is more standard. The unquoted value is interpreted as a definition that doesn't actually exist, so it's assumed to be a string.
