<?php
header("Content-type:text/html;charset=utf-8");
/**
* 读取当前目录下的文件和目录
* 
* @param    string    $path    路径
* @return    array    所有满足条件的文件
*/
function tlist($path){
    $path = iconv('utf-8', 'gbk', $path);
    if(!is_dir($path)){
        throw new Exception($path."不是目录");
    }
    $arr = array('dir'=>array(),'file'=>array());
    $hd = opendir($path);
    while(($file = readdir($hd))!==false){
        if($file=="."||$file=="..") {continue;}
