首先使用一个浏览器来访问应用的一个页面 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问另一个页面 multex_session2.php
在该页面中会找到该账号之前使用的sessionId,然后清除该sessionId保存的所有内容,然后重新写入session值,并将新的sessionId写入redis中
清除旧的sessionId使用的方法有 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();
}
