------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))
路径中包含汉语言时，PHP解析失败
