这篇文章主要介绍了php实现url加密解密的方法,结合实例形式分析了php针对url字符串进行加密解密操作的相关技巧,需要的朋友可以参考下

具体如下：

<html xmlns="#" lang="zh-CN">
<head>
<meta http-equiv="content-type" content="text/html; charset=gb2312" />
<meta http-equiv="content-language" content="zh-CN" />
<meta http-equiv="pragma" content="no-cache" />
<meta http-equiv="expires" content="0" />
<meta http-equiv="MSThemeCompatible" content="Yes" />
<meta http-equiv="imagetoolbar" content="no" />
<meta http-equiv="widow-target" content="_top" />
<meta name="robots" content="index, follow" />
<meta name="author" content="3945, [email]ljm77@km169.net[/email]" />
<meta name="keywords" content="" />
<meta name="description" content="" />

<style type="text/css">
<!--
a, a:link{text-decoration: none; color:#000000; font-size:9pt;}   a:visited{text-decoration: none; color:#000000;}   a:hover{text-decoration: underline; color:red;}
body, td, p, li, p, select{font-size:9pt; font-family:"宋体";}
-->
</style>
</head>
<body>
<?php
function query_encode($sQuery)
{//加密链接
  if(strlen($sQuery)==0)
   {
     return '';
   }
   else
   {
    $s_tem = preg_replace("/&/i", '&', $sQuery);
    $s_tem = preg_replace("/&/i", '&', $s_tem);
    $a_tem = explode('&', $s_tem);
    shuffle($a_tem);
    $s_tem = implode('&', $a_tem);
    $s_tem = rawurlencode($s_tem);
    $s_tem = base64_encode($s_tem);
    $s_tem = strrev($s_tem);
     return $s_tem;
   }
}
function query_decode($sEncode)
{//解密链接
  if(strlen($sEncode)==0)
   {
     return '';
   }
   else
   {
    $s_tem = strrev($sEncode);
    $s_tem = base64_decode($s_tem);
    $s_tem = rawurldecode($s_tem);
     return $s_tem;
   }
}
function rebuild_GET()
{//重写$_GET全局变量
  $_GET = array();
  $s_query = $_SERVER['QUERY_STRING'];
   if(strlen($s_query)==0)
   {
     return;
   }
   else
   {
    $s_tem = query_decode($s_query);
    $a_tem = explode('&', $s_tem);
     foreach($a_tem as $val)
     {
      $tem = explode('=', $val);
      $_GET[$tem[0]] = $tem[1];
     }
   }
}
rebuild_GET();
echo 'GET:<div class="code" style="position:relative; padding:0px; margin:0px;"><pre class="brush:php;toolbar:false">'.print_r($_GET, true).'
