What is the best way to filter out specific information, like video IDs, from URLs using regular expressions in PHP?

To filter out specific information, like video IDs, from URLs using regular expressions in PHP, you can use the preg_match function to extract the desired information based on a pattern. For example, if you want to extract video IDs from YouTube URLs, you can create a regular expression pattern that matches the video ID format and use preg_match to extract it. 

$url = 'https://www.youtube.com/watch?v=VIDEO_ID';
$pattern = '/(?:\?v=|\/embed\/|\/\d\/|\/vi?|=)([a-zA-Z0-9_-]{11})/';
preg_match($pattern, $url, $matches);
$video_id = $matches[1];
echo $video_id;
