How to extract domain from a certain url

I am trying to create a script that will extract the domain from a certain URL but no success. For example of url is http://www.testurl.tld/page1/2 I want to extract the domain from that url so the result must be testurl.tld

Thanks in advance

 

If the url is in $url, try doing:

$domain = parse_url($url,PHP_URL_HOST);

PHP:
