PHP e-commerce system development: Agile development method

Agile development is a software development methodology that emphasizes iterative and incremental development and teamwork. For developing complex e-commerce systems, agile methods can provide great flexibility and adaptability.

Agile development process

Agile development follows the following process:

1. ##Requirements gathering and prioritization:Collection and analyze user needs and prioritize them.
2. Iteration planning: Break development work into smaller, manageable iterations based on prioritized requirements.
3. Iterative development: In an iteration cycle, the team focuses on completing relevant requirements.
4. Daily Scrum: Team members gather together daily to discuss progress, obstacles, and upcoming tasks.
5. sprint review and retrospective: At the end of each iteration, the team reviews and reviews the work done, gathers feedback, and plans improvements.

Practical Case: Developing Shopping Cart Function

The following is a practical case of agile development using PHP to develop shopping cart function:

// 购物车类
class Cart {
    private $items = [];

    public function addItem(Product $product) {
        $this->items[] = $product;
    }

    public function getTotal() {
        $total = 0;
        foreach ($this->items as $item) {
            $total += $item->getPrice() * $item->getQuantity();
        }
        return $total;
    }
}

// 产品类
class Product {
    private $name;
    private $price;
    private $quantity;

    public function __construct($name, $price, $quantity) {
        $this->name = $name;
        $this->price = $price;
        $this->quantity = $quantity;
    }

    public function getName() {
        return $this->name;
    }

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

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

// 用例
$cart = new Cart();
$cart->addItem(new Product('苹果', 10, 2));
$cart->addItem(new Product('香蕉', 8, 3));

echo "购物车总价：" . $cart->getTotal(); // 输出 44
