Of course, in this particular example you'll get the trailing slash. For a more general approach, you could do something like (untested):

        $v = "http://www.php.net/";

        function get_domain_part($url, $number_of_levels) {
           $rval = '';
           $url_parts = parse_url($url);
           if (is_array($url_parts) && !empty($url_parts['host'])) {
              $host_parts = explode('.', $url_parts['host']);
              $count = count($host_parts);
              for ($i=$count; $i > max(0,$count-$number_of_levels); $i--) # this line fixed
                 { $rval = $host_parts[$i-1].'.'.$rval; }
              $rval = substr($rval, 0, -1);
           }
           return $rval;
        }

So,

        $v = "http://www.php.net/";

        echo get_domain_part($v, 2);

should produce 'php.net', and

        echo get_domain_part($v, 1);

should produce 'net', and so on. -steve +- Obscure computer humor, item 77: -------------------------------------+
