会话结束后如何在PHP中自动设置注销

Question

Please do not mark this as duplicate just by looking at the title. I've seen some post related to this. But couldn't find one matching my query.

I am creating a web-site with user login. On the index page I've set

session_set_cookie_params(7200);

so that the session will be active for 2 hours even if browser is closed. But I want the user to be logged out after 2 hours.

I have created the website so that user can login anytime and it will stay for 2 hours. But how to modify it so that page is available for two hours fixed, say (9-11 am) regardless of when the user logs in the time between?

Answer 1

Save in your database the login time of the user.

Compare then the current time with the login time and see if it's more than two hours.

If so, perform the logout.

Pseudocode:

$currentDate = date('U');
$loginDate   = $dateComingFromTheDatabase; // UNIX timestamp

if (($currentDate - $loginDate) >= 7200)
{
    PerformLogout();
}
