redirecting useres from specific referrers

[a!!!!1]

I'm sending traffic to a .php on my server, and I want to redirect all users who come from 'google' to a specific url, and all else are redirected to another url. How do I do this? Thanks :)

use the HTTP var to check the referrer, and then the header() function

Thanks but I barely understand PHP so writing it myself is a little hard, lol.

<?php
$ref = = $_SERVER['HTTP_REFERER'];

if(strstr($ref,"google")) {
header("Location: http://www.peoplefromgooglegohere.com/");
} else {
header("Location: http://www.otherpeoplegohere.com/");
}
?>
