Stripping url with preg_replace

I needed to strip the 

http://www.

from a domain name and also anything following it such as

/example

so that i would just be left with yourdomain.com

I added the following code to a file:

$domain = HTTP_SERVER;
$domain_name = preg_replace('/^https?:\/\/(?:www\.)?/i', '', $domain);

But if i echo $domain_name I still get a url such as yourdomain.com/testsite

Can anyone see what i have done wrong here as it has not removed the /testsite and i thought i had got this right.

This may be a hack that someone will disagree with, but i resolved the problem by using the following code.

$url = HTTP_SERVER;
$parse = parse_url($url);
$domain = $parse['host'];
$domain_name = preg_replace('/(?:www\.)?/i', '', $domain);
echo $domain_name;

If you can see a reason why this should not be used, please feel free to let me know. Always something new to learn :)

use this

$url = 'http://www.example.co.uk/directory/level1/last/page.html'; 
$parse= parse_url($url); 
preg_match ("/\.([^\/]+)/", $parse['host'], $mydomain); 
echo $mydomain[1];
