function getYouTubeInfo($video_id){  

    $content = file_get_contents("http://youtube.com/get_video_info?video_id=" . $video_id);    

    parse_str($content, $ytarr);  

    return $ytarr;  

}  

  

$video_id = 'psvkyf3PzjE';    

$ytinfo = getYouTubeInfo($video_id);  

  

echo '<meta http-equiv="content-type" content="text/html;charset=utf-8">';  

echo '<p><strong>'.$ytinfo['title'].'</strong></p>';     // 标题  

echo '<p><img src="'.$ytinfo['thumbnail_url'].'"></p>';  // 缩略图  

echo '<p><img src="'.$ytinfo['iurlmq'].'"></p>';         // 中图  

echo '<p><img src="'.$ytinfo['iurl'].'"></p>';           // 大图  

  

echo '<pre>';  

print_r($ytinfo);  

echo '</pre>';
