How to extract the domain name from a URL

[Gian04]

preg_match('@^(?:http://)?([^/]+)@i', $inputtext, $matches);
$host = $matches;

preg_match('/[^.]+\.[^.]+$/', $host, $matches);
echo "domain name is: {$matches[0]}\n";

The code above will return the correct domain is the user input is something like http://www.example.com

But if the input is http://www.example.co.uk it will return co.uk

also it will accept an input like abc@.com (will return abc@.com as domain)

Anyone who has a better solution?

dc, please explain how can I implement this, it just display my own domain name.

What I want to do is to check for the domain in a user input URL and to be able to check if its already present in the database.

thanks

How about using parse_url() [php.net]?
