one liner RegEx to get ID from url

Question

I need a 1 liner RegEx to get the ID from a url. I am using this but it does not return the id. Any idea? for the following it should return 1396. The RegEx I tried are below and none of them worked.

/(?<=id=)[^&]+/`

and (?<=ID=)\w+(?=,)

Use parse_url() and parse_str().

exmple get Id from youtube url

   <?php
$url = "http://www.youtube.com/watch?v=C4kxS1ksqtw&feature=relate";
parse_str( parse_url( $url, PHP_URL_QUERY ), $my_array_of_vars );
echo $my_array_of_vars['v'];    
  // Output: C4kxS1ksqtw
?>

If ID is always numeric:

/\WID=(\d+)/

This matches a non word character then ID= then captures all the following digits.
