function get_filetree_scandir($path){
  $result = array();
  $temp = array();
  if (!is_dir($path)||!is_readable($path)) return null; //检测目录有效性
  $allfiles = scandir($path); //获取目录下所有文件与文件夹
  foreach ($allfiles as $filename) { //遍历一遍目录下的文件与文件夹
    if (in_array($filename,array('.','..'))) continue; //无视 . 与 ..
    $fullname = $path.'/'.$filename; //得到完整文件路径
    if (is_dir($fullname)) { //是目录的话继续递归
      $result[$filename] = get_filetree_scandir($fullname); //递归开始
    }
    else {
      $temp[] = $filename; //如果是文件,就存入数组
 			$uniqid = uniqid('apoo_');
      $ext = pathinfo($filename, PATHINFO_EXTENSION);
      rename($fullname,$path.'/'.$uniqid.'.'.$ext);
    }
  }
  foreach ($temp as $tmp) { //把临时数组的内容存入保存结果的数组
    $result[] = $tmp; //这样可以让文件夹排前面,文件在后面
  }
