The codes not working =.=
I've followed all the instructor code. However in my browser showing error. How to solve the undefined $id? Where is the $id point to? Could you at least explain it?
On line fifteen of her code, $id is the parameter passed to the function (single_item_array) when it is used/called.
Does that make sense?
I hope that helps.
Stay safe and happy coding!
