preg_match youtube id and remove url

Question

I'm trying to get the youtube video id and replace the url with just the youtube video id. So far I found a way to get the video id, but I can't seem to remove the url.

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

Examples:

   http://youtu.be/dQw4w9WgXcQ ...
   http://www.youtube.com/embed/dQw4w9WgXcQ ...
   http://www.youtube.com/watch?v=dQw4w9WgXcQ ...
   http://www.youtube.com/?v=dQw4w9WgXcQ ...

   http://www.youtube.com/watch?feature=player_embedded&v=dQw4w9WgXcQ ...

Note that a youtube url can also have extra params after the video id.

Much help is appreciated. Thanks!

by remove the URL maybe you are wanting to use preg_replace rather than just preg_match — hackartist, Apr 14 '12 at 20:54
The preg_match is working. I just can't find a way to replace the url with the video id — user962449, Apr 14 '12 at 20:54

For all your example urls this preg_replace works. Additionally removes any params after the video ID

$videoID =  preg_replace("#[&\?].+$#", "", preg_replace("#http://(?:www\.)?youtu\.?be(?:\.com)?/(embed/|watch\?v=|\?v=|v/|e/|.+/|watch.*v=|)#i", "", $url));

It has trouble handling params after the youtube id. – user962449 Apr 14 '12 at 21:18
Try this string `hello my name is :) testing [tag] [/tag] http://www.youtube.com/embed/dQw4w9WgXcQ?yup=2&t=2 hello this is another test :) ;)` – user962449 Apr 14 '12 at 21:19
okay, edited one more time, now it should also replace the params if starting with a "?" – Andreas Linden Apr 14 '12 at 21:30

Try this:

<?php
$url = 'http://www.youtube.com/?v=dQw4w9WgXcQ&foo=bar&test=baz';
$path = parse_url($url, PHP_URL_PATH);
$query = parse_url($url, PHP_URL_QUERY);
parse_str($query, $args);
echo "http://www.youtube.com/watch?v=". $args['v'];
