referring domain

[mikeyzc]

I would like to start a session when a page loads and grab the domain name that the user came to my page from. Is there a function to do this?

You could use something like this:

<?PHP
$refurl = $_SERVER['HTTP_REFERER'];
$refurl = explode("/", $refurl);
$refurl = $refurl[0]."//".$refurl[2];
session_start();
$_SESSION['referrer'] = $refurl;
?>

One note about referrer -- not every client sends it, and it is easy to spoof.
