index.php
<html>
<head>
<title>文件浏览</title>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<style type="text/css">
<!--
a:link {text-decoration: none;}
a:visited {text-decoration: none;}
a:hover {text-decoration: none;}
a:active {text-decoration: none;}
.style1 {font-size: 12px}
-->
</style></head>
<body><h3 align="center">文件浏览</h3>
<div align="center">
