FoodOrder

Testing ground for the Food and Order classes.

Food Class

This class implements the FoodInterface interface. It uses these methods:

• name()
• price()
• getName() (Accessor from the FoodInterface interface)
• getPrice() (also from the FoodInterface interface)

Order Class

This class is composed of Food objects. It uses these methods:

• addItem()
• removeItem()
• getItems() (returns an array of Food objects)
• getNames()
• getPrices()
• getAllNamesAndPrices()
• rawTotal()

Here is an example using the Order class:

<?php
namespace GMH;

// Require the Order class
require_once 'Order.php';

$order = new Order();

// Use method chaining
$fries = new Food();
$fries->name("French Fries")->price('3.50');
$pizza = new Food();
$pizza->name('Pepperoni Pizza')->price('11.95');

$order->addItem($fries)->addItem($pizza);

// Raw Total:
echo $order->rawTotal();

// Set a discount and a tax rate
$order->discount(10)->tax(8);

// Get the total after discount and tax
echo $order->totalWithTax();
