if(preg_match_all($ypattern,$link, $output))
{ 
    foreach ($output[4] AS $video_id)
    {

Youtube Headers

$headers = get_headers('http://gdata.youtube.com/feeds/api/videos/' . $video_id)`;

     if (strpos($headers[0], '200'))
     {
    $youtube = simplexml_load_file('http://gdata.youtube.com/feeds/api/videos/'.$video_id.'?v=1');
            $json = json_decode(file_get_contents('http://gdata.youtube.com/feeds/api/videos/'.$video_id.'?v=2&alt=jsonc'));

$thumbnail = $json->data->thumbnail->sqDefault;
                }
            }
