Can someone help me with the code of the Basket class?
(Snippets by category: Shopping Carts)
I am beginner into working with classes and manipulating data within arrays.

The sample that comes with the code enables you to add and remove items to/from a cart.

After adding,
- the quantity is not showed
- the itemname is not showed

After removal of the last item, there is an error

Somehow it doesn't work; if you are willing to help you can take a look at my sample at
sample of cart

I will be very happy if someone will help me understanding this code and make it work!

Thanks for your suggestion it made me look better to the code and I learned that the -> is necessary to call functions from within a class (which is the case)

The NN in the output was typed (!) as text in the sample. I replaced the code that checks if there are items in the basket by this:

if(count($b) > 0) {
$b->printItems($b);
}

printItems is also a function in the class basket so I just used it. And the way of checking using count that you suggested works fine and reads better for me too so thanks again!

I will continue to understand the rest of the class.
