How can I destory a session after specific period of time?

Question

I want after the user log in to count 60 seconds then if he stayed more than 60 sec without being active it will destroy the session (when I click refresh on the browser)

Answer 1

Try this:

if (isset($_SESSION["LAST_ACTION"]) && (time() - $_SESSION["LAST_ACTION"] > 60))
{
session_unset();
session_destroy();
}

$_SESSION["LAST_ACTION"] = time();
