Why do multi-user mall systems specifically use PHP for back-end development?

With the rapid development of the e-commerce industry, the mall system has become an essential tool for many enterprises. The multi-user mall system meets the needs of multiple merchants to settle and manage. When developing a multi-user mall system, choosing the right back-end development language is crucial. As a language widely used in web development, why has PHP become the first choice for multi-user mall systems? This article explores this issue and provides some relevant code examples.

1. Open Source
   PHP is an open source language with a large developer community, which makes the PHP ecosystem very rich. For complex projects such as multi-user mall systems, the open source feature can help developers quickly build basic frameworks and modules, and the system can be repaired and improved through community support. Moreover, open source PHP frameworks such as Laravel and CodeIgniter provide rich functions and tools that can greatly simplify the development process.

The following is a simple PHP code example to handle the function of user registration:

<?php
    // 接受表单提交的数据
    $username = $_POST['username'];
    $password = $_POST['password'];

    // 对密码进行加密处理
    $hashedPassword = password_hash($password, PASSWORD_DEFAULT);

    // 连接数据库并插入新用户数据
    $conn = new mysqli("localhost", "username", "password", "database");
    $sql = "INSERT INTO users (username, password) VALUES ('$username', '$hashedPassword')";
    $result = $conn->query($sql);

    // 根据插入结果返回相应的信息
    if ($result) {
        echo "用户注册成功！";
    } else {
        echo "用户注册失败！";
    }
?>

2. Easy to learn
   Compared with other back-end languages, PHP is more Easy to learn. Its syntax and structure are relatively intuitive, making it less difficult for beginners to get started. This allows developers to quickly get started with the functional modules of the development city system, and at the same time, they can customize and expand it at any time.

The following is a simple PHP code example for the function of getting a user list:

<?php
    // 连接数据库获取用户列表
    $conn = new mysqli("localhost", "username", "password", "database");
    $sql = "SELECT * FROM users";
    $result = $conn->query($sql);

    // 将用户列表转化为JSON格式并返回
    $users = array();
    while ($row = $result->fetch_assoc()) {
        $user = array(
            'id' => $row['id'],
            'username' => $row['username'],
            'email' => $row['email']
        );
        array_push($users, $user);
    }
    echo json_encode($users);
?>

3. Lots of resources and documentation
   Due to the wide application of PHP, There are a large number of PHP related resources and documents on the Internet. Developers can read and refer to these resources to solve the problems and confusion encountered in the development of multi-user mall systems. At the same time, there are also many development teams and communities that provide a wealth of tutorials and cases, which are very beneficial to both beginners and experienced developers.

In summary, choosing PHP as the back-end development language for a multi-user mall system has several obvious advantages. Open source, easy to learn, and abundant resources and documentation make PHP an ideal choice for handling complex mall system functions. Of course, choosing an appropriate back-end language should also be comprehensively considered based on actual needs and the technology stack of the development team.
