I don't have experience of the Zend script you're referring to, but this
sounds to me like a classic situation for an array session variable.

What you're describing is a shopping cart, really. I would suggest
registering a session variable called somthing like $order, and adding
things to it. It'll be an array (arbitrarily deep), so the order
information could be stored in that. For example the array might contain
(untested):

$_SESSION['order'] = array(
pizza => array (type => 'quattro formaggi', quantity => 1),
pasta => array (item => 'carbonara', quantity => 2),
italianchefsalad_junior => array (quantity => 1)
)

etc, etc.

That way, you could always refer to the session array $order to find out
what was on the buyers list (untested):

foreach ($_SESSION['order'] as $dish => $details) {
echo $dish.":<br>";
foreach ($details as $detail => $information) {
echo $detail.": ".$information."<br>";
}
echo "<br>";
}

this will give you something like:

pizza:
type: quattro formaggi
quantity: 1

pasta:
type: carbonara
quantity: 2

italianchefsalad_junior:
quantity: 1

Or you could find the quantity of italianchefsalad_junior at
$_SESSION['order']['italianchefsalad_junior']['quantity'].

Clearly the data structure needs to be carefully thought through, and my
suggested one is probably totally inappropriate for your application,
but you might get the idea.
