Whats the best way?

Well this is the first time actually creating a regex. It works, but was wondering if the regex was created properly. HTTP_ACCEPT_LANGUAGE is 'en-us, en;q=0.75, nl;q=0.50, fr;q=0.25' /* Explode the browser report to get each language */ $foo = split(',', $_SERVER['HTTP_ACCEPT_LANGUAGE'] ); /* Perform a regex to get the first 2 letters for each language reported */ foreach ($foo as $bar) { $string = preg_replace("/([a-z]{2})|(-[a-z]{2})|(;q=[0-9]\.[0-9]{2})/i", "$1", trim($bar)); $array[] = $string; } Thanks
