Swoole and workerman development skills: How to develop more efficiently?

Swoole and Workerman are currently popular PHP asynchronous network programming frameworks. They have high performance and high concurrency processing capabilities, and are especially suitable for developing real-time communications, game servers, etc. that need to handle a large number of concurrent connections. Applications. This article will introduce some development skills of Swoole and Workerman to help developers use these two frameworks for development more efficiently.

1. Select the framework
First, choose the appropriate framework according to actual needs. Swoole provides a complete set of asynchronous network programming solutions, including TCP/UDP server, HTTP server, WebSocket server, etc., suitable for building various network applications. Workerman is more focused on asynchronous long-connect communication, such as chat rooms, real-time push and other scenarios. Therefore, when you need to handle massive concurrent connections, it is recommended to choose Swoole; for scenarios such as long-term connection communication, you can use Workerman.

2. Asynchronous programming thinking
Asynchronous programming is the core feature of Swoole and Workerman, and it is also the biggest difference from the traditional synchronous model. The traditional synchronous model blocks and waits on each connection, while the asynchronous model can handle multiple connections at the same time, improving concurrent processing capabilities. When developing, you need to change to an asynchronous programming way of thinking, rationally use callback functions, coroutines and other mechanisms to avoid blocking operations.

3. Reasonably set the number of concurrent connections
When dealing with a large number of concurrent connections, it is necessary to set the number of concurrent connections reasonably to maintain server stability and performance. Swoole can set the number of worker processes by setting the worker_num parameter, and each worker process will handle a portion of the connections at the same time. Workerman can set the number of worker processes by setting $worker->count. Properly setting the number of worker processes can make full use of the server's CPU and memory resources and improve performance.

4. Make full use of coroutines
Coroutines are a method of asynchronous programming that can greatly simplify code logic. In Swoole, you can use co::create() to create a coroutine, and then use co::sleep(), co::gethostbyname(), etc. function to perform asynchronous operations. Workerman uses the Yield feature to implement coroutine-like functions. Using coroutines can avoid nesting of callback functions and improve code readability and maintainability.

The following is a simple Swoole server example, used to handle client connections and data reception:

<?php
$serv = new SwooleServer("127.0.0.1", 9501);

// 监听连接事件
$serv->on('connect', function ($serv, $fd) {
    echo "Client: new connection. fd[$fd]
";
});

// 监听数据接收事件
$serv->on('receive', function ($serv, $fd, $from_id, $data) {
    echo "Received data from client[$fd]: $data
";
    // 处理业务逻辑
});

// 监听连接关闭事件
$serv->on('close', function ($serv, $fd) {
    echo "Client[$fd] closed
";
});

// 启动服务器
$serv->start();

5. Proper use of native PHP functions
Both Swoole and Workerman support native PHP functions , you can continue to use existing code and libraries. For example, use extension functions such as MySQLi and Redis to perform database operations, or use Composer to install third-party libraries for development. This improves development efficiency while reducing modifications to existing code.

6. Monitoring and debugging
During the development process, monitoring and debugging is very important. Both Swoole and Workerman provide some monitoring and debugging tools, such as swoole_server_stats, swoole_server_status, ps and other commands. Use these tools to view server status, number of connections, memory usage and other information in real time for performance analysis and optimization.

Summary
By choosing the appropriate framework, setting the number of concurrent connections appropriately, making full use of coroutines and other techniques, developers can help developers use Swoole and Workerman for development more efficiently. At the same time, rational use of native PHP functions and monitoring and debugging tools can further improve development efficiency and debugging capabilities. By mastering these skills, I believe you can develop more stable and efficient network applications.
