本文实例讲述了PHP简单实现单点登录功能。分享给大家供大家参考，具体如下：

1.准备两个虚拟域名

127.0.0.1 www.openpoor.com
127.0.0.1 www.myspace.com

2.在openpoor的根目录下创建以下文件

index.PHP

<?phpsession_start();?><!DOCTYPE html><html><head><meta charset="UTF-8"/><title>sync login</title></head><body><?php if(empty($_SESSION['username'])):?>hello,游客;请先<a href="login.php" rel="external nofollow" >登录</a><a href="http://www.myspace.com/index.php" rel="external nofollow" rel="external nofollow" >进入空间</a><?php else: ?>hello,<?php echo $_SESSION['username']; ?>;<a href="http://www.myspace.com/index.php" rel="external nofollow" rel="external nofollow" >进入空间</a><?php endif; ?> <a href="http://www.openpoor.com/index.php" rel="external nofollow" >home</a></body></html>

<?phpsession_start();if(!empty($_POST['username'])){ require '../Des.php'; $_SESSION['username'] = $_POST['username']; $redirect = 'http://www.openpoor.com/index.php'; header('Location:http://www.openpoor.com/sync.php?redirect='.urlencode($redirect).'&code='.Des::encrypt($_POST['username'],'openpoor'));exit;}?><!DOCTYPE html><html><head><meta charset="UTF-8"/><title>sync login</title></head><body><form action="" method="post"> <input type="text" name="username" placeholder="用户名"/> <input type="text" name="password" placeholder="密码"/> <input type="submit" value="登录"/></form></body></html>

sync.php

<?php$redirect = empty($_GET['redirect']) ? 'www.openpoor.com' : $_GET['redirect'];if(empty($_GET['code'])){ header('Loaction:http://'.urldecode($redirect)); exit;}$apps = array( 'www.myspace.com/slogin.php');?><!DOCTYPE html><html><head><meta charset="UTF-8"/><?php foreach($apps as $v): ?><script type="text/javascript" src="http://<?php echo $v.'?code='.$_GET['code'] ?>"></script><?php endforeach; ?><title>passport</title></head><body><script type="text/javascript">window.onload=function(){ location.replace('<?php echo $redirect; ?>');}</script></body></html>

3.在myspace的根目录下创建如下文件

slogin文件完成session的设置

<?phpsession_start();header('Content-Type:text/javascript; charset=utf-8');if(!empty($_GET['code'])){ require '../Des.php'; $username = Des::decrypt($_GET['code'],'openpoor'); if(!empty($username)){  header('P3P: CP="CURa ADMa DEVa PSAo PSDo OUR BUS UNI PUR INT DEM STA PRE COM NAV OTC NOI DSP COR"');  $_SESSION['username'] = $username; }}?>
