How to choose: Comparison of Swoole and Workerman development technologies

Introduction:
In the development of modern network applications, it is very important to choose a suitable development technology . Swoole and Workerman are both tools commonly used by PHP programmers when developing high-performance network applications. This article will conduct a comprehensive comparison of these two technologies to help readers better choose the development technology suitable for their own projects.

1. Overview
Swoole is a high-performance network communication engine based on PHP. It provides an asynchronous, non-blocking network programming interface and is suitable for developing high-concurrency and high-performance network applications. Workerman is another PHP network programming framework that builds high-performance network applications by using multi-process and event polling technology. They all have high performance characteristics, but each has different characteristics and applicable scenarios.

2. Performance comparison

1. Number of concurrent connections
   In terms of the number of concurrent connections, Swoole has higher performance than Workerman. Swoole can handle a large number of concurrent connections based on an asynchronous and non-blocking method, and is suitable for high-performance communication requirements. Workerman adopts a multi-process model. Each process is responsible for independent connections and can also handle a large number of concurrent connections.
2. Process Management
   In terms of process management, Workerman is more flexible. Through the multi-process model, Workerman can start and manage processes as needed, conveniently and flexibly adjusting the use of resources. Swoole uses one or more processes to handle all connections. There is less communication between processes, but it may lead to a waste of resources.

3. Programming model and code examples

1. Swoole Programming Model
   Swoole provides coroutine support, making it easy to write asynchronous code using the synchronous programming model. The following is a code example using Swoole for network programming:

<?php
$server = new SwooleServer("0.0.0.0", 9501);

$server->on('connect', function ($server, $fd){
    echo "Client: Connect.
";
});

$server->on('receive', function ($server, $fd, $from_id, $data) {
    $server->send($fd, "Server: " . $data);
});

$server->on('close', function ($server, $fd) {
    echo "Client: Close.
";
});

$server->start();

2. Workerman Programming Model
   Workerman adopts an event-driven programming model that can easily handle a large number of concurrent connections. The following is a code example using Workerman for network programming:

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

use WorkermanWorker;

$worker = new Worker("tcp://0.0.0.0:2345");

$worker->count = 4;

$worker->onMessage = function($connection, $data)
{
    $connection->send('Hello ' . $data);
};

Worker::runAll();

4. Ecosystem and community support
Both Swoole and Workerman have large open source communities, with rich third-party libraries and extensions . Swoole is more mature in high-performance web application development in PHP and more active in ecosystem and community support. Workerman is more popular in some specific scenarios (such as real-time chat, game servers, etc.), and the community also has many related extensions and cases.

5. Selection of applicable scenarios
Selecting appropriate development technology requires comprehensive consideration of the needs of the project. If the project has very high performance requirements and the implementation is relatively complex, Swoole is a good choice. If the project has high performance requirements but is relatively simple, Workerman is also a good choice.

6. Summary
Swoole and Workerman are both good tools for PHP programmers to develop high-performance network applications. They have some differences in performance, programming models, ecosystems, and applicable scenarios. To choose a development technology suitable for your own project, you can make trade-offs and choices based on the actual project needs and project scale, taking these factors into consideration.
