Extract the YouTube Video ID from a URL in PHP

youtube_id_regex.php

<?php
// Here is a sample of the URLs this regex matches: (there can be more content after the given URL that will be ignored)

// It also works on the youtube-nocookie.com URL with the same above options.
// It will also pull the ID from the URL in an embed code (both iframe and object tags)

preg_match('%(?:youtube(?:-nocookie)?\.com/(?:[^/]+/.+/|(?:v|e(?:mbed)?)/|.*[?&]v=)|youtu\.be/)([^"&?/ ]{11})%i', $url, $match);
$youtube_id = $match[1];
?>

Not working on https://youtube.com/live/… Edit: just added |live/ works for me now:

preg_match('%(?:youtube(?:-nocookie)?\.com/(?:[^/]+/.+/|(?:v|e(?:mbed)?)/|.*[?&]v=|live/)|youtu\.be/)([^"&?/ ]{11})%i', $url, $match);
    $youtube_id = $match[1];

Works perfect, thanks!
