Swoole and Workerman are two very popular PHP development frameworks. They have powerful functions in message push and subscription. In this article, we will delve into the application scenarios of Swoole and Workerman in PHP and MySQL, and give specific code examples.
1. Swoole application scenarios
// 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, $frame) { foreach ($server->connections as $fd) { // 将收到的消息广播给所有连接 $server->push($fd, $frame->data); } }); // 监听WebSocket连接关闭事件 $server->on('close', function (SwooleWebSocketServer $server, $fd) { echo "connection close: {$fd} "; }); // 启动服务器 $server->start();
// 创建Swoole的异步任务服务器 $server = new SwooleServer('0.0.0.0', 9502, SWOOLE_PROCESS, SWOOLE_SOCK_TCP); // 设置异步任务的工作进程数量 $server->set(['task_worker_num' => 4]); // 监听服务器的连接事件 $server->on('connect', function ($server, $fd) { echo "Client {$fd} connect "; }); // 监听服务器的接收数据事件 $server->on('receive', function ($server, $fd, $fromId, $data) { // 模拟耗时任务 $taskId = $server->task($data); echo "Async task {$taskId} start "; }); // 监听异步任务完成事件 $server->on('task', function ($server, $taskId, $fromId, $data) { // 完成任务,例如将结果存入数据库 // ... // 返回任务结果 $server->finish($data); }); // 监听异步任务完成回调事件 $server->on('finish', function ($server, $taskId, $data) { echo "Async task {$taskId} finish "; }); // 启动服务器 $server->start();
2. Workerman’s application scenario
// 创建Workerman的Websocket服务器 $worker = new WorkermanWorker('websocket://0.0.0.0:2345'); // 监听WebSocket连接打开事件 $worker->onConnect = function ($connection) { // 向连接客户端推送实时数据 $connection->send('Hello, Welcome to Realtime Data Statistics!'); }; // 监听WebSocket消息事件 $worker->onMessage = function ($connection, $data) { // 处理具体的业务逻辑 $result = processData($data); // 广播实时数据给所有连接 broadcast($result); }; // 启动服务器 WorkermanWorker::runAll();
// 创建Workerman的订阅发布服务器 $broker = new WorkermanBrobroker(); // 监听'publish'事件 $broker->on('publish', function ($topic, $message) { // 处理收到的消息 handleMessage($topic, $message); }); // 处理接收到的订阅请求 function handleMessage($topic, $message) { // 处理具体的业务逻辑 // ... // 发布消息给指定的订阅者 $broker->publish($topic, $message); } // 启动服务器 $broker->run();
Summary:
As can be seen from the above sample code, Swoole and Workerman both have powerful functions in message push and subscription. They are suitable for different application scenarios respectively. For example, Swoole is suitable for real-time communication applications, while Workerman is suitable for real-time data statistics and subscription publishing systems. In actual development, we can choose the appropriate framework for development according to needs to improve the performance and flexibility of the project.
