Basic Shopping Cart - Job Application Task

About

This is a simple task assigned to me during a job interview. The task was to write a PHP class for a shopping cart.

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+

Achievements

• All requirements achieved.
• Tested with PHP 7.3.
