here’s how i would do it. id in first capture group.
youku\.com/(?:player.php/sid/|v_show/id_)([a-zA-Z0-9]+)(?:/|\\.)
i understand now that you use php as application language, which changes things a bit. you have to start and end the regular expression with a formality character of your own choice. for this regular expression i’d use the hash character, since it’s not used anywhere in the regular expression:
$regExp = "#youku\.com/(?:player.php/sid/|v_show/id_)([a-zA-Z0-9]+)(?:/|\\.)#";
