Doesn't work

[bakomon]

Example:

function get_domain($url) {
  $str = '/^(?:https?.\/\/)?(?:[^@\/\n]+@)?(?:)?([^:\/?\n]+).*/m';
  preg_match_all($str, $url, $matches, PREG_SET_ORDER, 0);
  foreach ($matches as $key => $value) {
    //var_dump($value);
    return $value[1];
  }
}
echo get_domain("http://www.s.id");
