首先使用一个浏览器来访谒应用的一个页面 multex_session1.php

要记录当前账号所使用的sessionId，，使用session_id()获取到当前的sessionId

然后用另一个浏览器和同一个账号访谒另一个页面 multex_session2.php

在该页面中会找到该账号之前使用的sessionId,然后断根该sessionId生存的所有内容，然后从头写入session值，并将新的sessionId写入redis中

断根旧的sessionId使用的要领有 session_start()????? ?session_unset() ? session_write_close()

具体代码：multex_session1.php

<?php $redis = new Redis(); $redis->connect('192.168.1.102',6379); session_start(); $curSessionId = session_id(); echo 'sessionId='.$curSessionId.'<br/>'; $userSession = $redis->get('online:1'); echo "userSession:{$userSession},user_id:{$_SESSION['user_id']},user_name:{$_SESSION['user_name']}"; $_SESSION['user_id'] = 1; $_SESSION['user_name'] = 'areyouok'; $redis->set('online:1', $curSessionId); $redis->expire('online:1', 1800); session_write_close();

multex_session2.php

<?php session_start(); $curSessionId = session_id(); echo 'sessionId='.$curSessionId.'<br/>'; session_write_close(); $redis = new Redis(); $redis->connect('192.168.1.102',6379); $oldSession = $redis->get('online:1'); if (!empty($oldSession) && !empty($curSessionId) && $curSessionId != $oldSession) { echo 'oldSession not equal new sessionId<br/>'; $redis->set('online:1', $curSessionId); $redis->expire('online:1', 1800); session_id($oldSession); session_start(); if (ini_get("session.use_cookies")) { $params = session_get_cookie_params(); echo 'arrive here,'.json_encode($params).'<br/>'; setcookie(session_name(), '', time() - 42000, $params["path"], $params["domain"], $params["secure"], $params["httponly"] ); } unset($_SESSION['user_id']); unset($_SESSION['user_name']); session_unset(); session_write_close(); session_id($curSessionId); session_start(); echo "oldSession:{$oldSession},user_id:{$_SESSION['user_id']},user_name:{$_SESSION['user_name']}"; $_SESSION['user_id'] = 1; $_SESSION['user_name'] = 'areyouok'; session_write_close(); }
