HTTP_REFERER problem...

[lazzerous]

Is there a way to use $HTTP_REFERER and only get the host name, removing whatever file and/or directory the link was placed.
Basically, if the user came from www.domain.com/links/links.html,
I just want www.domain.com returned.

Thank you all in advance for any help you might provide - I truly appreciate it.

$refer = split("/",$HTTP_REFERER);
$refer = $refer[2];

http://www.foo.bar/file.txt = array(http:,,www.foo.bar,file.txt)
