this should work for any web address starting with www.

// test for domain

$domain = "www.example.com";

// This pattern will match anything that STARTS with www followed by a
period, followed by at least 2 characters,
// numbers and periods followed by a period followed by at least two
characters
$pattern = "#^www\.([a-zA-Z0-9.-]{2,}\.[a-zA-Z]{2,})$#";

if(preg_match($pattern, $domain, $matches))
{
echo 'Matched. Domain is: '.$matches[1];
} else {
echo 'NO MATCHY DUDE';
}
