Question

If I have a variable that contains a URL, then how can I get the base URL? That is,

$url = 'http://www.domain.com/some/stuff/that/I/do/not/want/';
$base_url = some_clever_function($url);
// $base_url is now set equal to 'domain.com'

How can I do this?

Answer 1

parse_url will be able to extract the host for you.

It has the second argument with the help of which you can extract different parts of URL. To extract host, use parse_url the following way:

$host = parse_url($url, PHP_URL_HOST);
