@preg_match('#/watch_fullscreen\?video_id=([a-z0-9-_]+)&l=([0-9]+)&t=([a-z0-9-_]+)#i', $data, $matches);

PHP:

Chances are YouTube have changed they way they output videos, so that line doesn't exist anymore. Just go to YouTube and see how it outputs it's video_id and other required parameters, and change your source accordingly.
