You are setting this up fundamentally wrong.
You should be using an array and looping through it.
Something like:
$myorder['cowface'] = 1;
$myorder['beefenweiner'] = 2;
$myorder['chucksteak'] = 1;
foreach ($myorder as $item => $quantity)
{
echo "Order: $item x $quantity\n";
}
Then your array only contains the items someone actually puchased and how
many.
