Mall order management system implemented with PHP

Mall order management system implemented with PHP

With the development of e-commerce, more and more merchants choose to sell products online. In order to better manage orders and improve operational efficiency, it is very necessary to develop an efficient order management system.

This article will introduce how to use PHP language to develop a simple but useful mall order management system. The following is a code example:

<?php
// 定义订单类
class Order {
    private $orderId;
    private $productId;
    private $productName;
    private $price;
    private $quantity;
    private $totalAmount;

    public function __construct($orderId, $productId, $productName, $price, $quantity) {
        $this->orderId = $orderId;
        $this->productId = $productId;
        $this->productName = $productName;
        $this->price = $price;
        $this->quantity = $quantity;
        $this->totalAmount = $price * $quantity;
    }

    public function getOrderId() {
        return $this->orderId;
    }

    public function getProductId() {
        return $this->productId;
    }

    public function getProductName() {
        return $this->productName;
    }

    public function getPrice() {
        return $this->price;
    }

    public function getQuantity() {
        return $this->quantity;
    }

    public function getTotalAmount() {
        return $this->totalAmount;
    }
}

// 定义订单管理类
class OrderManager {
    private $orders;

    public function __construct() {
        $this->orders = array();
    }

    public function addOrder($orderId, $productId, $productName, $price, $quantity) {
        $order = new Order($orderId, $productId, $productName, $price, $quantity);
        array_push($this->orders, $order);
    }

    public function getOrderById($orderId) {
        foreach ($this->orders as $order) {
            if ($order->getOrderId() == $orderId) {
                return $order;
            }
        }
        return null;
    }

    public function getTotalRevenue() {
        $totalRevenue = 0;
        foreach ($this->orders as $order) {
            $totalRevenue += $order->getTotalAmount();
        }
        return $totalRevenue;
    }
}

// 测试代码
$orderManager = new OrderManager();
$orderManager->addOrder(1, 1001, "商品1", 10.5, 2);
$orderManager->addOrder(2, 1002, "商品2", 5.99, 3);
$orderManager->addOrder(3, 1003, "商品3", 20, 1);

$order = $orderManager->getOrderById(2);
if ($order != null) {
    echo "订单ID：" . $order->getOrderId() . "<br>";
    echo "产品ID：" . $order->getProductId() . "<br>";
    echo "产品名称：" . $order->getProductName() . "<br>";
    echo "单价：" . $order->getPrice() . "<br>";
    echo "数量：" . $order->getQuantity() . "<br>";
    echo "总金额：" . $order->getTotalAmount() . "<br>";
} else {
    echo "未找到相关订单！";
}

$totalRevenue = $orderManager->getTotalRevenue();
echo "总收入：" . $totalRevenue;
?>

The above code example defines an Order class to represent a single order, including attributes such as order ID, product ID, product name, unit price, quantity, and total amount. The OrderManager class is used to manage multiple orders. You can add orders, find orders based on order IDs, and calculate total revenue.

Through the test code, we can see how to use the OrderManager class to add orders, find order display related information based on the order ID, and calculate the total revenue of all orders.

The above example is just a simple mall order management system, which can be expanded and optimized according to actual needs. I hope this example can help you better understand the application of PHP to mall order management.
