Workerman Network Programming Introduction: Creating high-performance server-side applications

In recent years, with the rapid development of the Internet, the demand for server-side applications has become higher and higher. In order to meet the access needs of large-scale users, developers need to learn high-performance network programming technology. As a high-performance network programming framework, Workerman provides a simple and powerful way to build server-side applications.

This article will introduce what Workerman is and how to use Workerman to develop high-performance server-side applications. At the same time, we will demonstrate the use of Workerman through some code examples.

1. Introduction to Workerman

Workerman is a high-performance network programming framework developed based on PHP. It adopts a multi-process, event-driven model and can easily handle highly concurrent requests.

Compared with traditional PHP servers, Workerman has the following advantages:

1. High performance: Workerman adopts an event-driven model and can efficiently handle a large number of requests. At the same time, it also supports multiple processes, allowing the server to handle multiple requests in parallel.
2. Multi-protocol support: Workerman supports multiple protocols such as HTTP and WebSocket, which can meet the development needs of different applications.
3. Easy to use: Workerman’s interface is simple and easy to understand, and developers can get started quickly.

2. Install Workerman

In order to use Workerman, you first need to install it. It can be installed through Composer. The command is as follows:

composer require workerman/workerman

After the installation is completed, you can start using Workerman.

3. Using Workerman

The following uses a simple example to demonstrate the use of Workerman.

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

use WorkermanWorker;

// 創(chuàng)建一個(gè)Worker監(jiān)聽端口為2345的socket，不傳參數(shù)默認(rèn)監(jiān)聽0.0.0.0
$worker = new Worker('tcp://0.0.0.0:2345');

// 啟動(dòng)4個(gè)進(jìn)程來處理客戶端連接
$worker->count = 4;

// 接收到客戶端連接時(shí)回調(diào)函數(shù)
$worker->onConnect = function ($connection) {
    echo "New connection
";
};

// 接收到客戶端消息時(shí)回調(diào)函數(shù)
$worker->onMessage = function ($connection, $data) {
    $connection->send('Hello ' . $data);
};

// 運(yùn)行worker
Worker::runAll();

The above code creates a Worker instance that listens on port 2345. When the client connects to the server, the onConnect callback function is triggered; when a message sent by the client is received, the onMessage callback function is triggered and the message sent by the client is returned to the client. Finally, start the Worker by calling Worker::runAll().

4. Summary

This article briefly introduces Workerman, a high-performance network programming framework, and shows how to use Workerman to develop server-side applications through sample code.

Through Workerman, developers can easily build high-performance server-side applications to meet the access needs of a large number of users. Using Workerman is not only highly efficient, but also has a simple and easy-to-understand interface, making it very suitable for beginners to get started.

At the same time, it should be noted that Workerman itself is only a network programming framework and does not provide database and other functions. Developers need to develop based on their actual needs in combination with other tools and technologies.

I hope this article will help you understand and use Workerman, and I wish you success in the development of server-side applications!
