CodeBuddy：社区交流网络开发的革命性助手

# 传统方式需要多步骤环境配置
$ apt-get install apache2
$ apt-get install php7.4
$ apt-get install mysql-server
$ apt-get install php7.4-mysql
$ ... (更多配置步骤)

# CodeBuddy方式：一键配置
$ codebuddy setup community-forum
# 自动完成所有环境配置，包括Apache、PHP、MySQL等

// 传统PHP代码可能存在SQL注入风险
function getUserInfo($username) {
    $query = "SELECT * FROM users WHERE username = '$username'";
    // 没有防SQL注入措施
    $result = mysql_query($query);
    return $result;
}

// CodeBuddy自动建议更安全的做法
function getUserInfo($username) {
    // CodeBuddy提示：使用参数化查询防止SQL注入
    $stmt = $conn->prepare("SELECT * FROM users WHERE username = ?");
    $stmt->bind_param("s", $username);
    $stmt->execute();
    return $stmt->get_result();
}
