------解决思路----------------------
你这样能不出错吗？
        while($fileName=readdir($fd))
        {
            $encoding=mb_detect_encoding($fileName,array("cp936","gbk" ,"gb2312", "utf-8","ISO-8859-1","ASCII"));
            $fileName=iconv($encoding,"utf-8",$fileName); //非utf-8的文件名被转成了utf-8的，那么文件还能存在吗？
             
            if($fileName !="." && $fileName !="..")
            {
             
                if(is_file($dirName.'/'.$fileName))
