使用jquery函数重置PHP $ _SESSION数组

I am trying to reset a session array in php with a function in jquery using a button. I would use a submit but I don't want the page to refresh. I tried to send a $.post request leaving the variables and return blank, and then sending a variable so I could use $_session[''] = array() but none of it worked. I have searched and can't find much about it just a lot on sending strings.

    OK this is very simple to stop the page from refreshing you need to tell js to disable the default event i use jquery for this here is my code

    Html & js 

    <html>
<head>
    <title>Reseting a PHP $_SESSIO array with jquery function</title>
    <script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
    <script src="http://code.jquery.com/jquery-migrate-1.2.1.min.js"></script>
    <script>

        function sessRest(){
            $.post("rest.php", {x: "9845621"}).done(function(data){
                alert("States: " + data);
            });
        }

        $(document).ready(function(){

            $("#target").click(function(event){
                event.preventDefault();
                sessRest();
            });
        });
    </script>
</head>
<body>
    <div id="main">
        <a href="#" id="target">Click to rest me</a>
    </div>
</body>
</html>

    php code rest.php

    <?php
session_start();

(string)$data = $_POST['x'];

if($data == "9845621"){
    $_SESSION['gx'] = array();
    return $_SESSION['gx']; //return the empty array to js
}else(
    return "error";
)


?>
