<html xmlns="http://www.w3.org/1999/xhtml" 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="" /><meta name="copyright" content="Copyright 3945 All Rights Reserved" /><title>无标题文档</title><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, div, select{font-size:9pt; font-family:"宋体";}--></style></head><body><?phpfunction 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]] = $tem[1];     }   }}rebuild_GET();echo 'GET:<pre>'.print_r($_GET, true).'</pre>';function testGET(){   echo 'Function GET:<pre>'.print_r($_GET, true).'</pre>';}testGET();?><br /><br /><br /><?for($i=1; $i<10; $i++){  $s_url = query_encode('ac=index:logo& style="color: #007700">.$i);   echo sprintf('<a href="?%s">TEST: %s</a><br />', $s_url, $s_url);}?></body></html>
