Question

Given this variable:

$variable = foo.com/bar/foo

What function would trim $variable to foo.com ?

Edit: I would like the function to be able to trim anything on a URL that could possibly come after the domain name.

Thanks in advance,

John

Working for OP:

$host = parse_url($url, PHP_URL_HOST);

The version of PHP I have to work with doesn’t accept two parameters (Zend Engine 1.3.0). Whatever. Here’s the working code for me – you do have to have the full URL including the scheme (http://). If you can safely assume that the scheme is http:// (and not https:// or something else), you could just prepend that to get what you need.

Working for me:

$url = 'http://foo.com/bar/foo';

$parts = parse_url($url);
$host = $parts['host'];

echo "The host is $host\n";
