Solution

Here's my answer:

<?php
$videos = array('https://www.facebook.com/nikololok/videos/t.100000216422619/10153335471682286/?type=2', 'https://www.facebook.com/nikololok/videos/10153335471682286/', 'https://www.facebook.com/videos/10153335471682286/);');
foreach($videos as $f_video){
    preg_match("~/videos/(?:t\.\d+/)?(\d+)~i", $f_video, $matches);
    print_r($matches);
}

I changed the delimiter to ~ so the /'s in the URL don't need to be escaped.
