PHP - Vimeo video detection for preg_match()

I'm trying to detect, whether my Vimeo link is in Vimeo format (http://www.vimeo.com/nnnnnnn)

I tried this:

preg_match("/http:\/\/(www\.)?vimeo\.com\/(\d+)/", $link);

However, it doesn't seem to work. Whats wrong? Thanks.

Solution 
  • preg_match("/https?:\/\/(?:www\.)?vimeo\.com\/\d{8}/", $input_line, $output_array);
