Do you have a simple example of how to create a multi-dimensional array and store it in a session variable?
...
you also asked for a class example, seeing as your asking for this I don't think your ready for the class example...
$_SESSION['mycart'] = array();
$_SESSION['mycart'][] = array('Product 1', 5.99);
$_SESSION['mycart'][] = array('Product 2', 4.99);
$_SESSION['mycart'][] = array('Product 3', 7.99);print_r($_SESSION['mycart']);
--- this works due to the superglobal $_SESSION; in order to use the $_SESSION var (accessable everywhere without the use of global keyword) you must first call session_start(), which in turn must be called before any output is sent to the browser.

As of PHP 4.1.0, $_SESSION is available as a global variable just like $_POST, $_GET, $_REQUEST and so on. Unlike $HTTP_SESSION_VARS, $_SESSION is always global. Therefore, you do not need to use the global keyword for $_SESSION. Please note that this documentation has been changed to use $_SESSION everywhere. You can substitute $HTTP_SESSION_VARS for $_SESSION, if you prefer the former. Also note that you must start your session using session_start() before use of $_SESSION becomes available.
