文件目录遍历的问题

gsntec 2013-07-31 10:47:16

原本是文件是显示第二层目录文件，我想让它显示第三层的文件，第二层的文件名以日期命名，第三层的文件以英文字母a、b、c等命名。弄了半天也没弄好，请教大神了。代码显示不下了，这是前半部分，主要包括文件目录的遍历。



<?php

$Lang='zh';

$psp = $_GET['sp'] + 0;

$ptt = $_GET['pt'] + 0;

if($psp <= 0 || $psp > 2) $psp = 1;

if($ptt <= 0 || $ptt > 5) $ptt = 1;

header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");

header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");

header("Cache-Control: no-store, no-cache, must-revalidate");

header("Cache-Control: post-check=0, pre-check=0", false);
