Call in a php function when Jquery timer reach to 0 - php

Question

Consider it as the user will login and only giving 45 minutes. How to call a PHP function which is log-out when the Jquery timer runs to 0.
Here's my Code
<script type="text/javascript">
function startTimer(duration, display) {
var timer = duration, minutes, seconds;
setInterval(function () {
minutes = parseInt(timer / 60, 10)
seconds = parseInt(timer % 60, 10);
minutes = minutes < 10 ? "0" + minutes : minutes;
seconds = seconds < 10 ? "0" + seconds : seconds;
display.text(minutes + ":" + seconds);
if (--timer < 0) {
timer = duration;
}
}, 1000);
}
jQuery(function ($) {
var FortyMinutes = 60 * 45,
display = $('#time');
startTimer(FortyMinutes, display);
});
</script>
And here's my php function
public function logout() {
session_destroy();
redirect('Authentication');
}

Answer 1

You will have to make a request to a new page.
Since PHP is a server side language you will have to go to another page to run any PHP code. This can be done by having a logout.php file:
<?php
logout();
public function logout() {
session_destroy();
redirect('Authentication');
}
?>
On the client side you can make an ajax request to that page. Run the following code after the timer is up.
$.ajax({
type: "GET",
url: 'logout.php',
success: function(data){
alert('Logging you out');
}
});
