how to pass the $_SESSION['var'] array to jquery and do ajax?

I have problem here, I need all the stuffs inside this $_SESSION['cart'] thing and pass it to jQuery to use it in a php-ajax file, my question is, how to do that?

Here's what I have in mind

function myfunc()
{
   //save cart to db of logged user
   $("a.savecart").click(function(){
       //how to assign the $_SESSION['cart'] into a js variable ?
         $.ajax({
            type: "POST",
            url: "classes/ajax.cart.php",
            data:  //what to put here ?
            success: function(data){
              alert(data);
              location.reload();
            }
         });
         return false;
       }
   });
}

Just echo it like below (just example):

data: {"cart_id" : <?php echo $_SESSION['cart']; ?>},

Or if your $_SESSION['cart'] is an associative array, you can use json_encode function.

data: <?php echo json_encode($_SESSION['cart']); ?>,

EDIT: For example, if your $_SESSION['cart'] is an array like below:

array(
    'id'  => 111;
    'num' => 222;
    //etc...
)

Then in your php ajax part, you could get the data by $_POST['id'] and $_POST['num'] etc...

Use json. If you have php > 5.2 on your server you can use json_decode and json_encode functions, see at manual. In data parameter you can use these trick:

data: 'jsondata={"some_key":"' + some_var + '"}'

attention you should use double quotes in key and value pair. So when it comes to script you can do that:

json_decode($_POST['jsondata']);

If the data you need is in session, then you can send empty ajax call and use $_SESSION['cart']. No need to pass it again.

OR

You can assign the value to a hidden field and use it in jquery as - 

 data:  $("#session_value").val(),
