Simple Shopping Cart

Objective

Write a simple PHP Class for a basic shopping cart.

Supplied

Products in an array (these do not require any editing).

Requirements

• The cart will need to keep its "state" during page loads / refreshes.
• List Products – these should be listed at all times to allow adding of products.
• Products should be listed in this format: product name, price, link to add product.
• Must be able to add a product to the cart.
• Must be able to view current products in the cart.
• Cart products should be listed in this format: product name, price, quantity, total, remove link.
• Product totals should be tallied to give an overall total.
• Must be able to remove a product from the cart.
• Adding an existing product will only update existing cart product quantity (e.g. adding the same product twice will NOT create two cart items).
• All prices should be displayed to 2 decimal places.
• Error checking will be set to strict for viewing completed code.
• Project will work as expected in PHP 7.0+.

This task should take 1-2 hours max. HTML look will not be a consideration when viewing the finished code.

Product List

<?php
// ######## please do not alter the following code ########
