PHP technology tutorial: Development method of shopping mall SKU management system

Introduction:
In today's e-commerce industry, shopping malls manage SKU (inventory) units) to control product inventory, sales and transactions. Developing an efficient and reliable SKU management system is crucial to the operation of shopping malls. This article will introduce how to use PHP technology to develop a shopping mall SKU management system.

1. Requirements analysis
Before development, a detailed requirements analysis must be conducted first. The main functions of the shopping mall SKU management system include: SKU (stock keeping unit) entry, editing, query, and deletion; real-time update of inventory; adjustment of SKU price and inventory; import and export of SKU, etc.

2. Database design
Before designing the database, it is necessary to determine the data tables required by the SKU management system. Commonly used data tables include: SKU table (containing SKU ID, name, price, inventory and other information), product table (containing product ID, name, description and other information), inventory table (recording SKU inventory), etc.

3. System Architecture Design
The architecture design of the SKU management system mainly includes three modules: front-end display, back-end logic and database processing. The front-end display uses HTML, CSS and JavaScript to display SKU information; the back-end logic is written in PHP to process front-end requests and interact with the database; database processing uses SQL statements to add, delete, modify and query the database.

4. Front-end development
Front-end development is mainly implemented through HTML, CSS and JavaScript. Use HTML and CSS to design the page layout for SKU display, and use JavaScript to implement data interaction and dynamic effects on the page. For example, Ajax technology can be used to realize real-time query and display of SKU information.

5. Back-end development
Back-end development is mainly written in PHP. PHP is an open source server-side scripting language that is easy to learn and use. In back-end development, PHP scripts need to be written to handle front-end requests and interact with the database.

1. To implement the SKU entry, edit, query and delete functions, you need to write PHP scripts to add, delete, modify and query the database.
2. To implement the SKU price and inventory adjustment function, you need to write a PHP script to process the corresponding data update logic.
3. To implement the import and export functions of SKU, you can read and write CSV files by writing PHP scripts.

6. Database Operation
In PHP, you can use extension libraries such as MySQLi or PDO to perform database operations. For example, using the MySQLi library, you can connect to the database and execute SQL statements through the following code:

$host = "localhost";
$username = "root";
$password = "password";
$dbname = "sku_management";

$connection = new mysqli($host, $username, $password, $dbname);

// 检查连接是否成功
if ($connection->connect_error) {
    die("连接失败: " . $connection->connect_error);
}

// 执行SQL语句
$sql = "SELECT * FROM sku";
$result = $connection->query($sql);

// 处理查询结果
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        // 输出每一行数据
        echo "ID: " . $row["id"]. " 名称: " . $row["name"]. " 价格: " . $row["price"]. "<br>";
    }
} else {
    echo "0 结果";
}

// 关闭连接
$connection->close();

7. System testing and launch
After the development is completed, system testing is required. Test each functional module of the system to ensure the normal operation of the system, data accuracy and system stability.

If the test passes, the system can be deployed to the online environment. You need to upload the code to the server, configure the server environment, and then let the mall administrator use and manage the system.

Conclusion:
The development method of shopping mall SKU management system can be summarized as demand analysis, database design, system architecture design, front-end development, back-end development, database operation, system testing and launch. I hope this article can provide some reference and guidance for developers who use PHP technology to develop shopping mall SKU management systems.
