$HTTP_REFERER question

[GORF]

I know I'm missing it

$HTTP_REFERER returns http://www.domain.com/whatever.html.

I need to pull just the domain or domain.com or www.domain.com out of the returned value of $HTTP_REFERER.

I will be pulling the $HTTP_REFERER from other sites hosted in my reseller account on the same server.

First, I'd suggest you don't use $HTTP_REFERER directly, since it is not available on servers with register_globals set to off. You can access it via $_SERVER['HTTP_REFERER'].

Second, you must be careful when relying on the referer. You cannot trust that a browser will send it. Some proxies also remove this header from the request, so it is possible that your script won't work.

And the answer to your question is http://www.php.net/parse_url.

Regards.

maybe $_SERVER['HTTP_HOST'] would be what your looking for....

<?
echo $_SERVER['HTTP_HOST'];
?>

run locally this output localhost

split it into an array using "/", then split each segment that into an array using "." The first segment that retuns two or more segments will be your domain.

Thanks everyone. I got what I needed.

dirname($_SERVER[HTTP_REFERER]) works fine. It was easier than splitting the array.
