I'm using this code to grab youtube videos information and it's working fine until I get an error when I try any video starts with (-) Minus Example: -VF0JwxQqcA
<?php
//The Youtube"s API url
define('YT_API_URL', 'http://gdata.youtube.com/feeds/api/videos?q=');
//Change below the video id.
$video_id2 = "$video_id2";
//Using cURL php extension to make the request to youtube API
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, YT_API_URL . $video_id2);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
//$feed holds a rss feed xml returned by youtube API
$feed = curl_exec($ch);
curl_close($ch);
//Using SimpleXML to parse youtube"s feed
$xml = simplexml_load_string($feed);
$entry = $xml->entry[0];
//If no entry whas found, then youtube didn"t find any video with specified id
if(!$entry) exit('Error: no video with id "' . $video_id2 . '" whas found. Please specify the id of a existing video.');
$media = $entry->children("media", true);
$group = $media->group;
$title = $group->title;//$title: The video title
$desc = $group->description;//$desc: The video description
$news_images = $group->thumbnail[0];//There are 4 thumbnails, the first one (index 0) is the largest.
//$thumb_url: the url of the thumbnail. $thumb_width: thumbnail width in pixels.
//$thumb_height: thumbnail height in pixels. $thumb_time: thumbnail time in the video
list($thumb_url) = $news_images->attributes();
$content_attributes = $group->content->attributes();
//$vid_duration: the duration of the video in seconds. Ex.: 192.
$vid_duration = $content_attributes["duration"];
//$duration_formatted: the duration of the video formatted in "mm:ss". Ex.:01:54
$source= "http://i.ytimg.com/vi/$video_id2/mqdefault.jpg";
?>
The error will be: Error: no video with id "-VF0JwxQqcA" whas found. Please specify the id of a existing video.
Any Help Please? Thanks
