遍历windows下的某个目录，将文件目录或文件显示出来。

<?php
ini_set('display_errors', 1);
$dir_handle=opendir("D:\\UPUPW_AP5.5\\temp\\");
//var_dump(mb_detect_order());
while(($readdir=readdir($dir_handle))!=false)
{
    $newchar=mb_convert_encoding($readdir,"gb2312","UTF-8");
    $char=iconv("UTF-8","gb2312",$readdir);
    echo $readdir."<br/>";

}
closedir($dir_handle);
?>

用了mb_convert_encoding和iconv函数编码转换都不行，php文件编码是UTF-8。
