CodeBuddy: 现代课程管理系统开发的理想助手

// 传统PHP代码 - 用户验证
function verifyUser($username, $password) {
    $query = "SELECT * FROM users WHERE NAME='$username' AND PASSW='$password'";
    $result = mysql_query($query);
    if(mysql_num_rows($result) > 0) {
        return true;
    }
    return false;
}

// CodeBuddy优化代码 - 用户验证
function verifyUser($username, $password) {
    // 防SQL注入处理
    $username = htmlspecialchars($username, ENT_QUOTES, 'UTF-8');
    
    // 使用参数化查询
    $stmt = $conn->prepare("SELECT * FROM users WHERE NAME = ?");
    $stmt->bind_param("s", $username);
    $stmt->execute();
    $result = $stmt->get_result();
    
    if($row = $result->fetch_assoc()) {
        // 使用安全的密码验证
        if(password_verify($password, $row['PASSW'])) {
            return true;
        }
    }
    return false;
}

# 传统方式：多步骤安装配置
$ apt-get install apache2
$ apt-get install php7.4 php7.4-mysql
$ apt-get install mysql-server
$ # 手动配置Apache
$ # 手动配置PHP
$ # 手动配置MySQL
$ # 手动创建数据库
$ # 手动设置权限

# CodeBuddy方式：一键安装配置
$ codebuddy-cli setup:lamp --project=course-management
# 自动完成所有安装和配置

# 传统方式：手动编辑Apache配置
$ vi /etc/apache2/apache2.conf
# 修改各种参数...

# CodeBuddy方式：智能服务器配置
$ codebuddy server:config
# 自动加载图形配置界面，提供最佳实践建议

// CodeBuddy数据库模型定义示例
$courseManagementDB = new Database('course_management');

// 定义用户表
$usersTable = $courseManagementDB->createTable('users')
