简易文件管理系统

我学习PHP做的第一个程序是文件管理，现在拿出来给大家，有什么缺点请指出来，这样有利于大家的学习和进步。也希望能对新手有所帮助。

index.php

<?php

if(isset($_GET['path']) && strlen(trim($_GET['path']))!=0){

$dir = $_GET['path'];

}else{

$dir = "/";

}

$pageSize = 20; //

$pageNum = 1; //

$pageTitle = 1; //

$fileTitle = 0; //

$folderTitle = 0; //

$currFileNum = 0; //

$currFolerNum = 0; //

if(isset($_GET['pagenum']))$pageNum = $_GET['pagenum'];

if($pageNum<1)$pageNum=1;

//echo $pageNum;
