copied!<p>You can use the PHP function <a href="http://php.net/manual/en/function.parse-url.php" rel="noreferrer"><code>parse_url</code></a> to extract host name, path, query string and the fragment. You can then use PHP string functions to locate the video id.</p> <pre><code>function getYouTubeVideoId($url) { $video_id = false; $url = parse_url($url); if (strcasecmp($url['host'], 'youtu.be') === 0) { #### (dontcare)://youtu.be/<video id> $video_id = substr($url['path'], 1); } elseif (strcasecmp($url['host'], 'www.youtube.com') === 0) { if (isset($url['query'])) { parse_str($url['query'], $url['query']); if (isset($url['query']['v'])) { #### (dontcare)://www.youtube.com/(dontcare)?v=<video id> $video_id = $url['query']['v']; } } if ($video_id == false) { $url['path'] = explode('/', substr($url['path'], 1)); if (in_array($url['path'][0], array('e', 'embed', 'v'))) { #### (dontcare)://www.youtube.com/(whitelist)/<video id> $video_id = $url['path'][1]; } } } return $video_id; } $urls = array( 'http://youtu.be/dQw4w9WgXcQ', 'http://www.youtube.com/?v=dQw4w9WgXcQ', 'http://www.youtube.com/?v=dQw4w9WgXcQ&feature=player_embedded', 'http://www.youtube.com/watch?v=dQw4w9WgXcQ', 'http://www.youtube.com/watch?v=dQw4w9WgXcQ&feature=player_embedded', 'http://www.youtube.com/v/dQw4w9WgXcQ', 'http://www.youtube.com/e/dQw4w9WgXcQ', 'http://www.youtube.com/embed/dQw4w9WgXcQ' ); foreach ($urls as $url) { echo sprintf('%s -> %s' .
