Real-time and reliability of Swoole and Workerman's message push in PHP and MySQL

Swoole and Workerman are two very popular PHP extensions, both of which can achieve high-performance network communication and message push functions. When pushing messages in PHP and MySQL, real-time and reliability are crucial factors. This article will introduce how to use Swoole and Workerman to implement real-time message push, and give specific code examples.

1. Swoole’s message push

Swoole is an open source, high-performance PHP network communication engine. It is based on PHP extension and provides features such as asynchronous IO, coroutine and multi-process, which can easily realize real-time message push. The following is a code example for using Swoole to implement real-time message push:

<?php
// 创建WebSocket服务器
$server = new SwooleWebSocketServer('0.0.0.0', 9501);

// 监听WebSocket连接打开事件
$server->on('open', function (SwooleWebSocketServer $server, $request) {
    echo "connection open: {$request->fd}
";
});

// 监听WebSocket消息事件
$server->on('message', function (SwooleWebSocketServer $server, $frame) {
    echo "received message: {$frame->data}
";

    // 在此处处理消息推送逻辑，比如将消息写入MySQL数据库

    // 广播消息给所有连接的客户端
    foreach ($server->connections as $fd) {
        $server->push($fd, $frame->data);
    }
});

// 监听WebSocket连接关闭事件
$server->on('close', function ($ser, $fd) {
    echo "connection close: {$fd}
";
});

// 启动服务器
$server->start();
?>

In the above code, we created a WebSocket server and listened to the connection's opening, message and closing events. After receiving the message, we can process the message push logic. Here we simply broadcast the message to all connected clients, you can perform more complex processing according to actual needs.

2. Workerman’s message push

Workerman is another high-performance PHP network communication engine, which provides real-time message push function in a multi-process manner. The following is a code example of using Workerman to implement real-time message push:

<?php
// 引入Workerman的自动加载文件
require_once __DIR__ . '/vendor/autoload.php';

use WorkermanWorker;

// 创建一个Worker监听9501端口，使用WebSocket协议通信
$ws_worker = new Worker("websocket://0.0.0.0:9501");

// 启动4个进程对外提供服务
$ws_worker->count = 4;

// 监听WebSocket连接打开事件
$ws_worker->onConnect = function ($connection) {
    echo "new connection
";
};

// 监听WebSocket消息事件
$ws_worker->onMessage = function ($connection, $data) {
    echo "received message: {$data}
";

    // 在此处处理消息推送逻辑，比如将消息写入MySQL数据库

    // 广播消息给所有连接的客户端
    foreach ($connection->worker->connections as $client_connection) {
        $client_connection->send($data);
    }
};

// 启动Worker
Worker::runAll();
?>

Workerman's code is very similar to Swoole's code. We also created a WebSocket server and listened to the connection opening and message events. Once the message is received, we can handle the message push logic there and broadcast the message to all connected clients.

3. Comparison between Swoole and Workerman

Swoole and Workerman are both very excellent PHP extensions, and both can realize the function of real-time message push. Their advantages and disadvantages are mainly reflected in the following aspects:

1. Performance: Swoole is better in terms of performance, mainly because it is written in C language, and the bottom layer is based on the epoll event polling model. More efficient.
2. In terms of scalability: Swoole is more scalable, provides rich APIs and functions, and can support more network communication scenarios.
3. In terms of learning curve: Compared with Swoole, Workerman has a gentler learning curve and is easier to get started.
4. Community and ecological aspects: Swoole has an active community and rich ecosystem, providing a large number of tutorials, documents and sample codes to facilitate developers to learn and use.

When choosing to use Swoole or Workerman, you need to decide based on actual needs and project conditions. No matter which extension you choose, you can implement real-time message push in PHP and MySQL and provide high-performance and reliable network communication.
