复制代码 代码如下:

function video_image($url){
   $image_url = parse_url($url);
     if($image_url[\'host\'] == \'www.youtube.com\' ||
        $image_url[\'host\'] == \'youtube.com\'){
         $array = explode(\"&\", $image_url[\'query\']);
         return \"http://img.youtube.com/vi/\".substr($array[0], 2).\"/0.jpg\";
     }else if($image_url[\'host\'] == \'www.youtu.be\' ||
              $image_url[\'host\'] == \'youtu.be\'){
         $array = explode(\"/\", $image_url[\'path\']);
         return \"http://img.youtube.com/vi/\".$array[1].\"/0.jpg\";
     }else if($image_url[\'host\'] == \'www.vimeo.com\' ||
         $image_url[\'host\'] == \'vimeo.com\'){
         $hash = unserialize(file_get_contents(\"http://vimeo.com/api/v2/video/\".
         substr($image_url[\'path\'], 1).\".php\"));
         return $hash[0][\"thumbnail_medium\"];
     }
