How do you strip out the domain name from a URL in php?

Question

Im looking for a method (or function) to strip out the domain.ext part of any URL thats fed into the function. The domain extension can be anything (.com, .co.uk, .nl, .what

Answer 1

You can use parse_url() to do this:

$url = 'http://www.example.com';
$domain = parse_url($url, PHP_URL_HOST);
$domain = str_replace('www.','',$domain);

In this example, $domain should contain example.com, irrespective of it having www or not. It also works for a domain such as .co.uk
