[讨论]如何实现在线zip解压缩
信息来源：邪恶八进制信息安全团队（[url=http://www.eviloctal.com/]www.eviloctal.com[/url]）
议题作者：antsniffer

在源码站点找到了一个PHP在线解压缩程序，经过实践，国内的空间大部分都可以正常解压缩
国外的部分空间解压缩不能完全（在含有二级文件夹的所有内容无法正常解压缩）
在线解压缩程序如下：
复制内容到剪贴板
代码:

<?php
//验证密码
$password = "123456";
?>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>在线解压ZIP文件程序 V1.0</title>
<style type="text/css">

</style>
</head>
<body>
  <form name="myform" method="post" action="<?=$_SERVER[PHP_SELF];?>" enctype="multipart/form-data" onSubmit="return check_uploadObject(this);">
<?
if(!$_REQUEST["myaction"]):
?>
<script language="javascript">
function check_uploadObject(form){
if(form.password.value==''){
  alert('请输入密码.');
  return false;
}
return true;
}
</script>
<table width="100%" border="0" cellspacing="0" cellpadding="4">
<tr>
   <td height="40" colspan="2" style="color:#FF9900"><p><font color="#FF0000">在线解压ZIP文件程序 V1.0</font></p>
   <p>使用方法:把zip文件通过FTP上传到本文件相同的目录下,选择zip文件;或直接点击“浏览...”上传zip文件。</p>

是不是和空间的权限设置有关系。
