The second-hand recycling website developed by PHP provides a quick channel to find goods

With the continuous improvement of people's environmental awareness, the second-hand recycling market is gradually emerging. Second-hand recycling websites have become the first choice for people looking for recycling channels for used items because of their convenience and sustainability. This article will introduce a second-hand recycling website developed based on PHP. Through this website, users can quickly and easily find the required recycling goods.

To show how to implement this website, we will use PHP's MVC architecture to develop it. MVC (Model-View-Controller) is a design pattern that divides the application into three independent components, namely Model, View and Controller. The model is responsible for processing the data, the view is responsible for displaying the data, and the controller is responsible for coordinating the interaction between the model and the view.

First, we need to create a database to store the user's recycling product information. The following is the structure of the database:

CREATE TABLE `goods` (
  `id` INT AUTO_INCREMENT PRIMARY KEY,
  `title` VARCHAR(255) NOT NULL,
  `description` TEXT,
  `price` DECIMAL(10, 2),
  `location` VARCHAR(100),
  `contact` VARCHAR(100),
  `image` VARCHAR(255)
);

Next, we define a model class named Goods to handle operations related to product information. The following is a code example of this class:

class Goods
{
    private $conn;

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

    public function getAllGoods()
    {
        $sql = "SELECT * FROM `goods`";
        $result = $this->conn->query($sql);
        return $result->fetchAll(PDO::FETCH_ASSOC);
    }

    public function getGoodsById($id)
    {
        $sql = "SELECT * FROM `goods` WHERE `id` = :id";
        $stmt = $this->conn->prepare($sql);
        $stmt->bindParam(':id', $id);
        $stmt->execute();
        return $stmt->fetch(PDO::FETCH_ASSOC);
    }

    // 其他操作方法...
}

Next, we need to create a view to display product information. Here is a simple example:

<?php foreach ($goods as $good): ?>
    <div class="good">
        <h3><?php echo $good['title']; ?></h3>
        <p><?php echo $good['description']; ?></p>
        <p>价格：<?php echo $good['price']; ?></p>
        <p>地点：<?php echo $good['location']; ?></p>
        <p>联系人：<?php echo $good['contact']; ?></p>
        <img src="<?php echo $good['image']; ?>" alt="<?php echo $good['title']; ?>">
    </div>
<?php endforeach; ?>

Finally, we need to create a controller to coordinate the interaction between the model and the view. The following is a code example of the controller:

class GoodsController
{
    private $model;

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

    public function index()
    {
        $goods = $this->model->getAllGoods();
        include 'view.php';
    }

    public function show($id)
    {
        $good = $this->model->getGoodsById($id);
        include 'detail.php';
    }

    // 其他操作方法...
}

Through the above code example, we can see the development process of the entire second-hand recycling website. Users can access the index method of the controller to display all product information, or they can access the show method of the controller and pass in the product ID to view detailed information of a specific product. When a user posts recycling items on the website, the controller will call the corresponding method of the model to process the data.

To sum up, the second-hand recycling website developed through PHP can provide users with a quick way to find goods. By using MVC architecture, we can clearly separate the various components of the application and perform different functions within them. This development model makes website maintenance and expansion easier.

Of course, this article only briefly introduces the development process of a second-hand recycling website based on PHP. In actual projects, more functions and details need to be considered. I hope this article can provide some inspiration to many developers who are interested in developing second-hand recycling websites.
