The second-hand recycling website uses the limited-time discount promotion function developed by PHP

In the current social context of increasing environmental awareness, the second-hand recycling market is gradually booming. In order to better meet user needs, many second-hand recycling websites have begun to introduce limited-time discount promotion functions. This article will introduce a limited-time discount promotion function developed using PHP.

1. Demand analysis

Before designing this limited-time discount promotion function, we need to analyze user needs. Users want to be able to enjoy discounted prices on products within a specific period of time. The specific requirements are as follows:

1. Users can browse ongoing limited-time discount activities on the website;
2. Users can view the original price and discounted price of products on the page of limited-time discount activities;
3. Users can add products to the shopping cart and enjoy discounted prices at checkout;
4. The system will automatically turn on or off limited-time discount activities within a specific period of time.

2. System design

Based on the above requirements, we can design a simple system. The system mainly includes the following parts: product management, discount activity management and shopping cart management. Among them, product management is used to manage product information, including the original price and inventory of the product; discount activity management is used to manage information about limited-time discount activities, including the start time, end time and discount price of the activity; shopping cart management is used to manage users Shopping cart information, including the products and quantities selected by the user.

The following is a simplified PHP code example to achieve the above requirements:

1. Commodity management:

   <?php
   class Product {
    private $id;
    private $name;
    private $price;
    private $quantity;
    
    public function __construct($id, $name, $price, $quantity) {
        $this->id = $id;
        $this->name = $name;
        $this->price = $price;
        $this->quantity = $quantity;
    }
    
    // 省略其他方法...
   }
   ?>

2. Discount event management ：

   <?php
   class DiscountActivity {
    private $id;
    private $start_time;
    private $end_time;
    private $discount_price;
    
    public function __construct($id, $start_time, $end_time, $discount_price) {
        $this->id = $id;
        $this->start_time = $start_time;
        $this->end_time = $end_time;
        $this->discount_price = $discount_price;
    }
    
    // 省略其他方法...
   }
   ?>

3. Shopping Cart Management：

   <?php
   class ShoppingCart {
    private $products;
    
    public function __construct() {
        $this->products = array();
    }
    
    public function addProduct($product) {
        array_push($this->products, $product);
    }
    
    public function getTotalPrice() {
        $totalPrice = 0;
        
        foreach ($this->products as $product) {
            $totalPrice += $product->price;
        }
        
        return $totalPrice;
    }
    
    // 省略其他方法...
   }
   ?>

3. Functional Implementation

After the system design is completed, we can start Implement specific functions. The following is a simplified PHP code example that implements the display of limited-time discount activities and the functions of shopping cart settlement:

<?php
// 获取正在进行的限时折扣活动
function getActiveDiscountActivities() {
    // TODO: 查询数据库，获取正在进行的限时折扣活动
    return array(); // 返回限时折扣活动的数组
}

// 获取商品的原价和折扣价格
function getProductPrice($product) {
    // TODO: 查询数据库，获取商品的原价和折扣价格
    return array($product->price, $product->price * 0.8); // 返回商品的原价和折扣价格
}

// 示例代码
$activeDiscountActivities = getActiveDiscountActivities();

foreach ($activeDiscountActivities as $discountActivity) {
    echo "活动时间：". $discountActivity->start_time. " - ". $discountActivity->end_time. "<br>";
    
    $product = new Product(1, "商品1", 100, 10);
    
    list($originalPrice, $discountPrice) = getProductPrice($product);
    
    echo "商品原价：". $originalPrice. "<br>";
    echo "商品折扣价：". $discountPrice. "<br>";
    
    $shoppingCart = new ShoppingCart();
    $shoppingCart->addProduct($product);
    
    echo "购物车总价：". $shoppingCart->getTotalPrice(). "<br>";
}
?>

The above code example simply implements the display of limited-time discount activities and the functions of shopping cart settlement. In actual projects, we can manage product, discount activity and shopping cart information through the database to achieve a more complete limited-time discount promotion function.

Summary: The limited-time discount promotion function developed using PHP can improve the user experience of second-hand recycling websites and enhance users' desire to purchase goods. Through simple system design and implementation, we can easily introduce limited-time discount promotion functions on second-hand recycling websites and expand the functions according to actual needs. I hope this article will help you understand the limited-time discount promotion function developed in PHP.
