I need to create a shopping cart and I cant figure out how to implement it without SQL.

don’t you want to save those shopping cart actions? I would definitely save it in a DB. ok, if you use a NoSQL DB, you don’t have to worry about SQL either ...

I honestly think you should start with MySQL. Learn how to connect them now rather than later. I don't really understand the point of not having a DB to back it all into and then creating dynamic links as well so that you don't have to create a new page for each item.
Personal Opinion though.

I don't see why everyone is so anti-this. It's a neat concept, not practical but who the hell cares.


The problem I see is your show makes little to no sense..

 foreach ($_SESSION['cart'] as $cart){
        echo "<td>". $itemID ."</td><td>". $quantity."</td></tr>";


Where is $itemID and $quantity coming from? You would probably have to do a foreach with a key to really get anything.

Something like this 
foreach($_SESSION['cart'] as $itemID => $quantity)
{
    echo "<td>". $itemID ."</td><td>". $quantity."</td></tr>";
}


Of course that is untested but I think it's closer than what you have.
