Domain

hyabusa

I've been trying to work on this for a little while now using a combination of functions and ideas.

I am trying to get the domain from a url, which is easy enough if you want the sub-domain aswell, but i don't :/

Example

http://www.mydomain.com/dir/dir/index.html = mydomain.com
http://test.mydomain.com = mydomain.com
http://test.mydomain.co.uk = mydomain.co.uk

The main problem is that the domain extension could have 1 (.com,.net,.org etc..) or 2 (.co.uk, .ac.uk etc..) parts.

If anyone has managed to do something similar i would be really glad of the help.

Thanks very much, Craig

You're looking for the function parse_url().

$url ='http://www.whatever.com/path/to/some/directory/';
extract(parse_url($url));

Now you have a variable $host which has the value 'www.whatever.com', as well as a couple others you may be interested in, too: $scheme, $port, $user, $pass, $path, $query, and $fragment.

Yeh but the problem is, that also includes the sub domain, which i need to get rid of.

Figured a bit of imagination could get you through the rest ...

The following works with every type of URL except the unlikely URL with more than one subdomain.

extract(parse_url($url));
$domain = explode('.', $host);
array_shift($domain);

if (count($domain) > 3) 
	array_shift($domain);
$host = implode('.', $domain);
