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.
