Menu
According to I build a chat support by PHP and use ajax for update chatting message.
on the system, there are 2 parts. first is admin team(different user), second is guest.
on PHP I create different SESSION name for them.
so every day at 5:00PM, the office will be close and all admin user will be logout
I can do this by crontab but my question is
How can I make all admin team logout? If answer is delete their SESSION.
So How can I delete their SESSION?
