I'm trying get the actual hostname of a domain the problem i face is subdomains. For example, i'm trying to produce a regex that could at least get all the follow to result in domain.com: sub.domain.com domain.co.uk domain.com sub.domain.co.uk sub.sub.domain.gov.uk etc.. Any ideas? Thanks!

Kalle The Addict Join Date: Sep 2007 Location: Denmark Posts: 241 Thanks: 5	You could use the parse_url() function built into PHP to fetch the domain name =) PHP Code: `<?php $url = 'http://www.talkphp.com/'; var_dump(parse_url($url)); ?>` Note, on invalid url's parse_url() will return false and throw an E_WARNING, so calling it with the error control operator prefixed (@). __________________
