Parsing YouTube Video ID Using preg_match

Problem:

Parsing the video ID from a YouTube URL using preg_match can be challenging, as shown by the original issue. The provided regular expression wasn't yielding the desired results due to syntax errors.

Solution:

if (preg_match('%(?:youtube(?:-nocookie)?\.com/(?:[^/]+/.+/|(?:v|e(?:mbed)?)/|.*[?&]v=)|youtu\.be/)([^"&?/\s]{11})%i', $url, $match)) {
