在一段时间不活动后将用户注销

Question

I want user to be logged out after some time inactivity. I want this php code to run automatically after some time of user inactivity. It must happen without refreshing the page.

<?php
    if (isset($_SESSION['user_login_status'])) {
        $max_time = 5; // Maximun inactive time(this time is set in seconds )
        $current = time(); // Current time on server

        if (!isset($_SESSION['Inactive']))
        { // Create session inactive;
          Session::set('Inactive', time()); // Create session inactive;
        } else {
            $session_life = $current - $_SESSION['Inactive'] ;

           if ($session_life > $max_time )
            {

             Session::destroy(); // This is a function that destroys all sessions and logging out the user
             header('location: index.php'); // Redirects to some kinda page 
            } else {
                $_SESSION['Inactive'] = time();
            }

        }
    }
?>

This php code is working and user is logged out after 5 seconds when I refresh the page. But I need this code to be runned after those 5 seconds of inactivity and it should redirect to another page. I have tried some ajax code but it didn't worked.

Any suggestions how can I Run that php code after some time?

A lot of misspelled words. Sorry for that.

Modify the code according to your needs. What this code would do is that if the user refreshes the page within 5 second, the timer will reset and start the count again. If user does not refresh/reload the page within 5 seconds, ajax call will be made to your controller action to log the user off. Return a new url to the ajax call to automatically redirect user to a new page. [FYI, I do not like automatic logoffs, specially such short ones. Of course, most Web servers have session timeouts. I would rather go with those timeouts.]

// add these functions at the bottom of the output html page within <script> tags
// YOU SHOULD CALL setLogoutTimer FUNCTION ON MOUSEMOVE OR SOME USER ACTIVITY EVENT.
// otherwise user will be logged out even when the user is doing something on the page



        setLogoutTimer();


    function setLogoutTimer() {
        var myTimeout;
        if (window.sessionStorage) {

            myTimeout = sessionStorage.timeoutVar;
            if (myTimeout) {
                clearTimeout(myTimeout);
            }

        }

        myTimeout = setTimeout(function () { logoutNow(); }, 5000);  //adjust the time. 
        if (window.sessionStorage) {
            sessionStorage.timeoutVar = myTimeout;
        }
    }

    function logoutNow() {
        if (window.sessionStorage) {
            sessionStorage.timeoutVar = null;
        }
        //MAKE AN AJAX CALL HERE THAT WILL CALL YOUR FUNCTION IN 
    // CONTROLLER AND RETURN A URL TO ANOTHER PAGE

    $.ajax({
            url: 'YOUR CONTROLLER ACTION URL',
            cache: false,
             async:false,
            type: 'POST',
            success: function (msg) {
                window.location.href=msg;  //msg is the url of another page returned by the controller


            }
        });
