用$ .ajax更改$ _SESSION

The actual page launch an $.ajax (POST) request and the receiver.php need to modify the $_SESSION. However it do not work, i don't know whether the id of $_SESSION is different or if i need a refresh on the page for register the modification.

I tried to transfer the session id and modifiy it with :

<?php
    if ( count( $_POST ) > 1 && isset( $_POST["s"] ) )
    {
        session_id( $_POST["s"] );
        session_start();
    }
?>

but this code is ineffective...

My $.ajax request is simple :

var s = <?php echo "'" . session_id() . "'"; ?>;

$.ajax({
    url: 'jquery/receiver.php',
    type: 'POST',
    dataType: 'html',
    data: {
        s: s, // session id, useless?
        // data...
    },
}).done(function ( data ) {
    // operations ...
}

My receiver.php too ;

<?php
    if ( count( $_POST ) > 1 && isset( $_POST["s"] ) )
    {
        session_id( $_POST["s"] );
        session_start();
    }

    $_SESSION['longarray']['key'] = 'value';
?>

Finally, it is possible to modify $_SESSION with $.ajax (POST) ? Or maybe i have only a problem because my $_SESSION is a array ?

    Ok I tried the following testp1.php

        <?PHP
        session_start();
    ?>
    <script type="text/javascript" src="../../common/jquery/jquery-1.10.2.min.js"></script>
    <script>
    $(document).ready(function () {
        var s = '<?php echo session_id(); ?>';

        $.ajax({
            url: 'receiver.php',
            type: 'POST',
            data: {
                s: s, // session id, useless?
                // data...
            },
            success: function(data){ console.log(data); }
        })
    })
    </script>
    <body>
    <?PHP
        echo $_SESSION['longarray']['key'];
    ?>
    </body>

    ajax call to receiver.php

    <?php
    if ( count( $_POST ) >= 1 && isset( $_POST["s"] ) )
    {
        session_id( $_POST["s"] );
        session_start();
        $_SESSION['longarray']['key'] = 'mix';
    }
    else
        echo "ERROR";;
?>

    On testp1.php the body shows mix
