Multidimensional Array

[golfinggod]

Hi can someone please show me how to add and additional item and its array to this multidimensional array

$_SESSION['cart'] = array(array( $item => array($quantity,$price)));

// I need to set up the code so that if the $item is not present it creates an aditional variable on the end of the array

$_SESSION['cart'][$item] = array($quantity, $price);
