Developing a highly available air ticket booking system based on Workerman

In recent years, with the rapid development of the aviation industry, the importance of air ticket booking systems has increased day by day. An efficient and highly available aviation booking system can provide convenient and secure booking services to meet the needs of passengers and airlines.

In this article, we will introduce how to use the Workerman framework to develop a highly available airline reservation system. Workerman is a high-performance PHP network framework that is easy to use, stable and reliable, and is very suitable for building large-scale real-time applications.

1. System design and architecture

Before designing the air ticket booking system, we need to clarify the functional requirements and architecture design of the system. A typical air ticket booking system should have the following functions:

• User registration and login
• Flight inquiry and reservation
• Ticket payment and refund
• Order Management and History

The architectural design of the system determines the scalability and stability of the system. In this system, we adopt a distributed architecture and deploy each functional module on different servers to improve the system's fault tolerance and concurrent processing capabilities.

2. Build a server using Workerman

First, we need to build a TCP long connection server based on Workerman on the server. This server is responsible for processing user requests for login, ticket booking, payment, etc., and forwarding the requests to the corresponding processing module.

The following is a simple server example:

require_once __DIR__ . '/vendor/autoload.php';

use WorkermanWorker;

$tcp_worker = new Worker("tcp://0.0.0.0:1234");
$tcp_worker->onMessage = function($connection, $data) {
    // 处理请求逻辑
    // ...
};

Worker::runAll();

3. User registration and login module

User registration and login are the basic functions of the air ticket booking system one. We can use the MySQL database to store user information and use the asynchronous IO library provided by Workerman for efficient database operations.

The following is an example of a simple user registration and login module:

// 用户注册
function register($username, $password) {
    $db = new WorkermanMySQLConnection('localhost', '3306', 'root', 'password', 'testdb');
    $res = $db->insert('users')->cols(['username' => $username, 'password' => $password])->query();
    return $res;
}

// 用户登录
function login($username, $password) {
    $db = new WorkermanMySQLConnection('localhost', '3306', 'root', 'password', 'testdb');
    $res = $db->select('*')->from('users')->where('username=:username AND password=:password')->bindValues(['username' => $username, 'password' => $password])->query();
    return $res;
}

4. Flight inquiry and booking module

Flight inquiry and booking are air ticket bookings The core functions of the system. We can use the Redis database to store flight information and use Workerman's asynchronous IO library for efficient database operations.

The following is a simple flight inquiry and booking module example:

// 航班查询
function search($departure, $arrival) {
    $redis = new Redis();
    $redis->connect('localhost', 6379);
    $res = $redis->get("flights:{$departure}:{$arrival}");
    return $res ? json_decode($res, true) : [];
}

// 航班预订
function book($flightId, $userId) {
    $redis = new Redis();
    $redis->connect('localhost', 6379);
    $redis->rpush("bookings:{$userId}", $flightId);
    return true;
}

5. Ticket payment and refund module

Ticket payment and refund is aviation Important functions of the ticket booking system. We can use the API provided by the third-party payment platform for payment and refund operations.

Here is a simple payment and refund module example:

// 机票支付
function pay($bookingId, $amount) {
    // 调用支付平台API进行支付操作
    // ...
    return true;
}

// 机票退款
function refund($bookingId, $amount) {
    // 调用支付平台API进行退款操作
    // ...
    return true;
}

6. Order Management and History Module

Order Management and History is Airline An important part of the ticket booking system. We can use the MySQL database to store order information and use Workerman's asynchronous IO library for efficient database operations.

The following is a simple order management and history module example:

// 订单管理
function manageOrders($userId) {
    $db = new WorkermanMySQLConnection('localhost', '3306', 'root', 'password', 'testdb');
    $res = $db->select('*')->from('orders')->where('user_id=:user_id')->bindValues(['user_id' => $userId])->query();
    return $res;
}

// 历史记录
function history($userId) {
    $db = new WorkermanMySQLConnection('localhost', '3306', 'root', 'password', 'testdb');
    $res = $db->select('*')->from('history')->where('user_id=:user_id')->bindValues(['user_id' => $userId])->query();
    return $res;
}

Through the above example, we can see how to use the Workerman framework to develop a highly available air ticket booking system. Through reasonable system design and architecture, and the use of tools and library functions provided by Workerman, we can develop a high-performance, highly available air ticketing system to meet user needs and improve user experience.

Summary

This article introduces how to develop a highly available air ticketing system based on the Workerman framework. We demonstrated development examples of key modules such as server setup, user registration and login, flight inquiry and booking, ticket payment and refund, order management and history records.

Using the Workerman framework, we can easily build a high-performance, high-availability aviation booking system, provide convenient and safe booking services, and meet the needs of users and airlines. I hope this article can provide readers with some reference and help when developing an air ticket booking system.
