Workerman’s development experience: Creating scalable large-scale network applications

Introduction:
In today’s Internet era, the development of large-scale network applications has become more and more important. In order to achieve high concurrency and low latency services, it is very critical to choose a suitable network framework. As a high-performance PHP network framework, Workerman provides our developers with a solution to quickly build scalable large-scale network applications. This article will share my experience in the development process of using Workerman, and combine it with code examples to demonstrate its powerful functions and ease of use.

1. Introduction to Workerman
Workerman is a PHP network framework developed by Chinese developer Mu Hong (walkor). It uses an event-driven approach to handle network requests and is implemented through PHP's built-in extension libevent. It has the characteristics of high performance, low resource consumption, and good scalability, and can be used to develop WebSocket, TCP, UDP and other types of network applications.

2. Experience

1. High performance:
   Workerman uses an event-driven approach to handle network requests. Compared with the traditional blocking HTTP framework, the performance has been significantly improved. promote. Through the event loop mechanism, multiple concurrent requests can be processed at the same time, making large-scale concurrent access possible.

Sample code:

require_once 'Workerman/Autoloader.php';

use WorkermanWorker;

$worker = new Worker('websocket://0.0.0.0:8000');

$worker->count = 4; // 开启4个进程

$worker->onMessage = function($connection, $data) {
    // 处理接收到的消息
};

Worker::runAll();

2. Scalability:
   Workerman supports multi-process mode and can dynamically adjust the number of worker processes according to actual needs to achieve load balancing and high efficiency. Available. At the same time, it supports distributed deployment, which can split business logic into different servers and distribute network load balancing to different nodes to improve service scalability.

Sample code:

require_once 'Workerman/Autoloader.php';

use WorkermanWorker;

$worker = new Worker('tcp://0.0.0.0:8000');

$worker->count = 4; // 开启4个进程

$worker->onConnect = function($connection) {
    // 处理客户端连接事件
};

Worker::runAll();

3. Ease of use:
   Workerman provides a simple and easy-to-use API interface, and developers do not need to pay attention to complex network protocols and event processing Mechanism, only need to focus on the implementation of business logic. At the same time, Workerman has built-in many commonly used extension plug-ins, such as chat rooms, instant messaging, push notifications and other functions.

Sample code:

require_once 'Workerman/Autoloader.php';

use WorkermanWorker;

$worker = new Worker();

$worker->onWorkerStart = function($worker) {
    // 定时任务
    Timer::add(1, function() {
        // 执行定时任务
    });
};

Worker::runAll();

End:
By using the Workerman framework, I personally feel its advantages in large-scale network application development. High performance, scalability, and ease of use enable us to quickly build scalable, large-scale network applications. I hope this article can help everyone understand the use and characteristics of the Workerman framework, help everyone apply it to actual projects, and jointly promote the development of Internet technology.
