Hostname Regex

Hey, it's been a while :-P

Kinda have a small issue. 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! ^^

are you trying to get the hostnames of your website or all the hostnames that have your word (in this example 'domain') from the Internet?

Just a hostname, they are purely examples. The "domain" part could be anything.

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 (@).
