  if(!is_string($url) || empty($url)) return ;
  if(strpos($url, 'swf')) return $url;
  preg_match_all('/http:\/\/(.*?)?\.(.*?)?\.com\/(.*)/', $url, $types);
  $type = $types[2][0];
  $domain = $types[1][0];
  switch ($type) {
    case 'youku' :
      preg_match_all('/http:\/\/v\.youku\.com\/v_show\/id_(.*)?\.html/', $url, $url_array);
      $swf = 'http://player.youku.com/player.php/sid/' . str_replace('/', '', $url_array[1][0]) . '/v.swf';
      break;
    case 'tudou' :
      $method = substr($types[3][0], 0, 1);
      $method = $method == 'p' ? 'v' : $method;
      preg_match_all('/http:\/\/www.tudou\.com\/(.*)?\/(.*)?/', $url, $url_array);
      $str_arr = explode('/', $url_array[1][0]);
      $count = count($str_arr);
      if ($count == 1) {
        $id = explode('.', $url_array[2][0]);
        $id = $id[0];
      } else if ($count == 2) {
        $id = $str_arr[1];
      } else if ($count == 3) {
        $id = $str_arr[2];
      }
      $swf = 'http://www.tudou.com/' . $method . '/' . $id . '/v.swf';
