shopping-cart

A shopping cart class implementation in PHP

It allows basic operations of a shopping cart; ie adding, removing, updating cart item through its quantity, listing all items in the cart, clearing items in the cart as well as calculating total cost of items in the cart.

Usage

Instantiate a Cart object passing in your source data. In a real application, you won't be passing data to the cart though. And in that case the constructor will not be needed.

$products = [
	[
		'id' => 1, 
		'name' => 'Smart Watch', 
		'price' => 45,  
		'description' => 'This Fitness Bracelet has a high sensitive touch screen'
	],
	...
];

$cart = new \App\Cart($products)

To test the sample application built with this class, clone the repository and run:
php -S localhost:8000 -t examples
