Workerman Network Programming Advanced: Implementing Efficient Game Servers

With the continuous development of the game industry, more and more game developers are beginning to pay attention to the game server Performance and efficiency. An efficient game server can provide a better gaming experience and attract more players. As a high-performance PHP network programming framework, Workerman is gradually becoming the first choice for game developers.

This article will introduce how to use Workerman to implement an efficient game server, and use code examples to help readers better understand.

1. Install and configure Workerman

First, we need to install the Workerman framework. Execute the following command in the terminal:

composer require workerman/workerman

After the installation is complete, create the start.php file in the project root directory and put the following content into it:

<?php
require_once './vendor/autoload.php';

use WorkermanWorker;

$worker = new Worker('tcp://0.0.0.0:1234');

$worker->onMessage = function ($connection, $data) {
    // 處理游戲邏輯代碼
};

Worker::runAll();

The above code creates a TCP The server listens on port 1234 of the local IP. When there is a new connection, the onMessage method will be triggered to handle the game logic.

2. Processing game logic

Next, let’s write the processing code for the game logic. In the onMessage method, we can perform logical processing and response according to specific game needs. The following is a simple example:

$worker->onMessage = function ($connection, $data) {
    switch ($data['action']) {
        case 'login':
            // 處理登錄邏輯
            $username = $data['username'];
            $password = $data['password'];
            // 驗(yàn)證用戶名和密碼，并返回結(jié)果
            $result = validate($username, $password);
            $connection->send($result);
            break;
        case 'move':
            // 處理移動(dòng)邏輯
            $x = $data['x'];
            $y = $data['y'];
            // 更新玩家位置
            updatePosition($connection, $x, $y);
            // 廣播給其他玩家
            broadcastPosition($connection);
            break;
        // 其他游戲邏輯處理...
    }
};

In the above example, we use switch statements to process different game logic based on different action fields. For example, when processing login logic, you can verify the username and password and return the verification results. When handling movement logic, the player's position can be updated and the position broadcast to other players.

3. WebSocket support

In order to support more complex real-time games, we can use Workerman's WebSocket support. WebSocket is a TCP-based protocol that enables full-duplex communication and is more lightweight and has lower latency.

First, we need to add the configuration of the WebSocket server in the start.php file:

$worker = new Worker('websocket://0.0.0.0:1234');

Then, we can process the WebSocket message in the onMessage method:

$worker->onMessage = function ($connection, $data) {
    $requestData = json_decode($data, true);
    switch ($requestData['action']) {
        // 處理具體的WebSocket邏輯
    }
};

The above code Convert the received WebSocket message into an associative array and handle different logic based on the action field.

4. Game data storage

As a game server, data storage and reading are very important. We can use a database or other caching mechanism to store and read data. Here, we take the MySQL database as an example:

// 連接數(shù)據(jù)庫(kù)
$mysqli = new mysqli('localhost', 'root', '123456', 'game');

// 處理登錄邏輯
function validate($username, $password)
{
    global $mysqli;
    $sql = "SELECT * FROM users WHERE username='$username' AND password='$password'";
    $result = $mysqli->query($sql);
    if ($result->num_rows > 0) {
        return 'success';
    } else {
        return 'fail';
    }
}

In the above code, we first use the mysqli class to connect to the MySQL database. Then, write the validate function to verify the username and password.

5. Run the server

Finally, we can execute the following command in the terminal to start our game server:

php start.php start

At this point, we have completed a simple Development of efficient game servers.

Summary:

Through the introduction of this article, we have learned how to use the Workerman framework to implement an efficient game server. At the same time, we also introduced in detail the processing of game logic, WebSocket support, and data storage through code examples.

However, as a complex game server, there are many other technologies and optimization methods that can be applied. However, I believe that through the introduction of this article, readers have already had a preliminary understanding of how to use Workerman to implement an efficient game server. I hope this article will be helpful to game developers, and let us work together to create a better gaming experience.
