//需要传两个参数，一个是我们需要删除的文件路径，比如：
  $path2= "./upload/picture/";
      $this->delDirAndFile($path,true);
//这是删除的方法
  public function delDirAndFile($path, $delDir = true) {
     if (is_array($path)) {
       foreach ($path as $subPath)
         $this->delDirAndFile($subPath, $delDir);
     }
     if (is_dir($path)) {
       $handle = opendir($path);
       if ($handle) {
         while (false !== ( $item = readdir($handle) )) {
           if ($item != "." && $item != "..")
             is_dir("$path/$item") ?  $this->delDirAndFile("$path/$item", $delDir) : unlink("$path/$item");
         }
         closedir($handle);
         if ($delDir)
