How to clear session of all users?

Is it possible to issue a command from a server (LAMP) that will destroy all current session variables? I want to be able to force all users off their session during periods of site maintenance. Is there an effective way of doing this or is this just silly?

Answer 1

Just like Paul commented above: you can delete the session storage. This will terminate all current user sessions, session data will be lost.

$sessionFiles = glob(session_save_path().'/*');
foreach($sessionFiles as $file) {
    if(is_file($file)) {
        unlink($file);
    }
}
