PHP为任意页面设访问密码

代码演示

代码简介

为你的页面支持加密访问无论什么程序只要是PHP程序都是支持这代码的来实现加密访问你的加密页面或文章等等的页面不保证其他程序可以正常使用麻烦先测试！

代码如下

<?php
/********************************************
* 使用方法:
*
* 1、将本段代码保存为 MkEncrypt.php
*
* 2、在要加密的页面前面引入这个 php 文件
* require_once('MkEncrypt.php');
*
* 3、设置页面访问密码
* MkEncrypt('页面密码');
*
********************************************/
// 密码 Cookie 加密盐
if(!defined('MK_ENCRYPT_SALT'))
define('MK_ENCRYPT_SALT', 'Kgs$JC!V');
/**
* 设置访问密码
*
* @param $password 访问密码
* @param $pageid 页面唯一 ID 值，用于区分同一网站的不同加密页面
*/
function MkEncrypt($password, $pageid = 'default') {
$pageid = md5($pageid);
$md5pw = md5(md5($password).MK_ENCRYPT_SALT);
$postpwd = isset($_POST['pagepwd']) ? addslashes(trim($_POST['pagepwd'])) : '';
$cookiepwd = isset($_COOKIE['mk_encrypt_'.$pageid]) ? addslashes(trim($_COOKIE['mk_encrypt_'.$pageid])) : '';
if($cookiepwd == $md5pw) return; // Cookie密码验证正确
if($postpwd == $password) { // 提交的密码正确
setcookie('mk_encrypt_' . $pageid, $md5pw, time() + 3600000, '/');
return;
}
?>
