php session destroy using ajax

Question

I would like it so that when someone presses a certain link that by using ajax it will run a php file to destroy a session and when its a success the current page will remove an item from Local Storage and then the page will redirect to the index page.

currently have the following but it doesn't work

JQUERY

$('#key a').click(function(e) {
                e.preventDefault();
                $.ajax({
                    type:"POST",
                    url:"/assets/inc/sign-out.php",
                    data:'',
                    dataType:'html',
                    context:document.body,
                    global:false,
                    async:false,
                    success:function(data){
                        console.log(data);
                        localStorage.removeItem("logged");
                        window.location.replace('/');
                    }
                });
            });

PHP

<?php 
include('config.php');
session_destroy();
?>

I'm not sure about the content of config.php but there should be a session_start() before session_destroy() — Adi

any error output? or does that success handler fire up correctly? did you try adding an error() function? — Zathrus Writer

@DonaldSutherland there is nothing in console.log because php doesn't return anything. If you know directly the name of the stored session key you can try unset() it. — Vit Kos

Try

<?php
// include 'config.php'; - does this config.php contain session related configuration like e.g. the cookie-name?

session_start(); // fetch/re-start current session
session_regenerate_id(true); // assign a new session id and delete old data
$_SESSION=array(); // empty session data
session_write_close(); // superfluous call ;-)

as your php script.

see http://docs.php.net/session_regenerate_id
