PHP会话超时回调? [英] PHP session timeout callback?

问题描述

我正在运行 PHP + APACHE + CENTOS Linux 组合.

I'm running a PHP + APACHE + CENTOS Linux combination.

我已经实现了登录 &登出网站.

I have implemented a login & logout on the website.

我的问题是，我怎么知道 php 会话何时超时(用户没有注销就关闭了浏览器)?

My question is, how can I know when the php session has timed-out (User has closed his browser without logging-out)?

原因是，当用户执行以下任何操作时，我想执行一些清理和/或数据库更新(调用另一个 PHP):(1) 退出或 (2) 超时

The reason is, I want perform some cleanups and/or database updates (calling another PHP) when the user has done any of the following: (1) LOGGED-OUT or (2) TIMED-OUT

我的猜测是我必须使用 Apache/Linux，对吗?

My guess is that I would have to make use of Apache/Linux, right?

推荐答案

您可以创建一个脚本，该脚本将以某种半固定的时间间隔运行(例如每 5 分钟一次，使用 crontab 作业)，而不是检测 php 会话何时超时最有可能)将自动注销/执行对过去一小时(或任何您的超时值)未处于活动状态的任何人的清理.只需在您的用户表中添加一个lastseen".

Instead of detecting when the php session times out, you could create a script that will run at some semi regular interval (every 5 minutes say, using a crontab job most likely) that will log out/perform the clean up for anyone who hasn't been active in the last hour (or whatever your timeout value is) automatically. Just add a 'lastseen' to your user table.
