PHP mall development skills: Design product recommendation and hot-selling functions

In modern e-commerce platforms, product recommendation and hot-selling functions are important factors in attracting user attention and increasing sales. Through reasonable design and implementation, the mall can recommend personalized products to users and display the best-selling products. This article will introduce some practical PHP development skills to help you achieve better mall product recommendation and hot-selling functions.

1. Database design

First, we need to store product information in the database. Create a table named "products", containing the following fields:

• id: product ID (primary key)
• name: product name
• price: product price
• description: product description
• image: product image path
• category: product category

In addition, we also need to create a file named " recommendations" table, used to store product recommendation information:

• id: recommendation ID (primary key)
• product_id: product ID
• user_id: user ID

2. Product recommendation function

The product recommendation function can display personalized recommended products to users based on their browsing and purchase history. The following is a simple sample code:

<?php
// 获取当前用户ID
$user_id = $_SESSION['user_id'];

// 查询推荐商品ID
$query = "SELECT product_id FROM recommendations WHERE user_id = $user_id";
$result = mysqli_query($connection, $query);

// 构建推荐商品列表
$recommendations = array();

while ($row = mysqli_fetch_assoc($result)) {
    $product_id = $row['product_id'];
    $recommendations[] = getProductDetails($product_id);
}

// 显示推荐商品
foreach ($recommendations as $product) {
    echo '<div class="product">';
    echo '<h3>' . $product['name'] . '</h3>';
    echo '<p>' . $product['description'] . '</p>';
    echo '<img src="' . $product['image'] . '" alt="' . $product['name'] . '">';
    echo '<p>¥' . $product['price'] . '</p>';
    echo '</div>';
}
?>

In the above code, please pay attention to replacing the corresponding database connection and the function to obtain product details.

3. Hot-selling function

The hot-selling function can display the highest-selling products and help users quickly discover popular products. The following is a simple sample code:

<?php
// 查询销量最高的商品ID
$query = "SELECT product_id FROM orders GROUP BY product_id ORDER BY COUNT(*) DESC LIMIT 5";
$result = mysqli_query($connection, $query);

// 构建热销商品列表
$hot_products = array();

while ($row = mysqli_fetch_assoc($result)) {
    $product_id = $row['product_id'];
    $hot_products[] = getProductDetails($product_id);
}

// 显示热销商品
foreach ($hot_products as $product) {
    echo '<div class="product">';
    echo '<h3>' . $product['name'] . '</h3>';
    echo '<p>' . $product['description'] . '</p>';
    echo '<img src="' . $product['image'] . '" alt="' . $product['name'] . '">';
    echo '<p>¥' . $product['price'] . '</p>';
    echo '</div>';
}
?>

Through the above code, we can get the ID of the product with the highest sales volume from the order table and display its details to the user.

Summary:

Through reasonable database design and PHP development skills, we can design and implement the product recommendation and hot-selling functions of the mall to improve user experience and sales. The above code examples can be used as your reference and can be modified and improved appropriately according to actual needs. Good luck with your mall development!
