Implementing high-concurrency online game server based on Workerman

High-concurrency online game server based on Workerman

In recent years, with the rapid development of online games, the performance and stability of online game servers have become particularly important . High concurrency is one of the biggest challenges that online game servers need to face. Workerman is a high-performance communication engine developed based on PHP. It provides a simple and easy-to-use interface and can easily implement high-concurrency network applications. This article will introduce how to use Workerman to implement a highly concurrent online game server, and attach corresponding code examples.

First, we need to install Workerman. It can be installed through Composer, just execute the following command:

composer require workerman/workerman

After the installation is completed, we can start writing our online game server code. The following is a simple example:

<?php
require_once __DIR__ . '/vendor/autoload.php'; // 引入 Workerman

use WorkermanWorker;

$worker = new Worker(); // 创建一个 Worker 对象
$worker->count = 4; // 设置进程数量
$worker->onWorkerStart = function($worker){
    // 此处编写游戏服务器启动时的逻辑
    echo "Game server started
";
};

$worker->onConnect = function($connection){
    // 此处编写新客户端连接时的逻辑
    echo "New client connected
";
};

$worker->onMessage = function($connection, $data){
    // 此处编写接收到客户端消息时的逻辑
    echo "Received message from client: " . $data . "
";
    $connection->send("Hello client!");
};

$worker->onClose = function($connection){
    // 此处编写客户端断开连接时的逻辑
    echo "Client disconnected
";
};

Worker::runAll(); // 启动 Worker

In the above code, we first introduced Workerman, then created a Worker object and set the number of processes. In the onWorkerStart callback function, we can write the logic when the game server starts. In the onConnect callback function, we can write the logic when a new client connects. In the onMessage callback function, we can write the logic when receiving the client message and send the message to the client through the $connection->send() method. In the onClose callback function, we can write the logic when the client disconnects.

With the above code, we have created an online game server based on Workerman. It should be noted that the above is just a simple example, and actual game servers may require more complex logic and functions. In addition, since Workerman is developed based on PHP, there may be some performance bottlenecks when processing computationally intensive tasks. For this situation, we can use multi-process, scheduled tasks, etc. to optimize.

In summary, it is feasible to implement a high-concurrency online game server based on Workerman. Workerman provides powerful functions and a simple and easy-to-use interface, which can meet the high concurrency requirements of online game servers. I hope this article can be helpful to developers who want to develop online game servers.
