scandir

php4是没有这个函数的 解决一下手册上有的 写出来当个笔记 ！

if(!function_exists('scandir')) {
  function scandir($dir = './', $sort = 0){
    $dir_open = @ opendir($dir);
    if (! $dir_open)
        return false;
        while (($dir_content = readdir($dir_open)) !== false)
        $files[] = $dir_content;
         if ($sort == 1)
            rsort($files, SORT_STRING);
        else
            sort($files, SORT_STRING);
    
        return $files;
    }
}
