Check youtube video is still valid

Check youtube video is still valid using youtube’s API

Manytimes youtube user can decide to delete their video. So I would
like to periodically run a script to check that the youtube video is still valid or not.

Also, you can fine best video review apps for shopify and make better your Shopify theme.

Suppose your Youtube url is : http://www.youtube.com/v/jc0rnCBCX2c
So here your Youtube video Id is jc0rnCBCX2c

$vid

posible format/sintax:

1. http://www.youtube.com/watch?v=[ID]&feature=…&…
2. http://www.youtube.com/watch?v=[ID]
3. www.youtube.com/watch?v=[ID]
4. youtube.com/watch?v=[ID]
5. http ://www.youtube.com/v/[ID]
6. www.youtube.com/v/[ID]
7. youtube.com/v/[ID]
8. [ID]
9. …. and any valid youtube video url

<?php
function checkYoutubeId($id) {
if (!$data = @file_get_contents("http://gdata.youtube.com/feeds/api/videos/".$id)) return false;
if ($data == "Video not found") return false;
return true;
}
?>

http://gdata.youtube.com/feeds/api/videos/jc0rnCBCX2c if it does not exist then you will get a page with “Invalid id” if it exists, will return an XML feed having various info about the video. this way you can check that the video exists.
<?php
function checkYoutube($vid) {
if (strlen($vid) < 12) { return checkYoutubeId($vid); }

	$preg1 = '@www.youtube.com\/watch\?v=(.*?)$@';
	if ( preg_match($preg1, $vid, $match) ) {
		$id = explode("&",$match[1]);   return checkYoutubeId($id[0]);
	}

	$preg1 = '@www.youtube.com\/v\/(.*?)$@';
	if ( preg_match($preg1, $vid, $match) ) {
		$id = explode("&",$match[1]);   return checkYoutubeId($id[0]);
	}
}
?>
