除了使用crontab的工作，当检测PHP会话超时，你可以创建一个脚本，将在一些半固定时间间隔（每5分钟说运行最有可能的），将注销/执行清理的人谁没有在最后时刻被激活（或任何你超时值）自动。只需添加一个'lastseen您的用户表。

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.
