How to implement the message broadcast function in Workerman documents

Since actual code examples are not suitable for display and explanation through plain text, I cannot provide complete code examples on this platform. But I can explain to you how to code the message broadcast function for your reference.

When using the Workerman framework to implement the message broadcast function, you can follow the following steps:

1. Instantiate a Worker object:

// 创建一个Worker监听端口
$worker = new Worker("websocket://0.0.0.0:8000");

2. Listen to the client connection event and save the client connection:

$worker->onConnect = function($connection) use ($worker) {
    // 保存客户端连接
    $worker->connections[$connection->id] = $connection;
};

3. Listen to the client disconnection event and clear the corresponding connection when the client disconnects:

$worker->onClose = function($connection) use ($worker) {
    // 清除断开的客户端连接
    unset($worker->connections[$connection->id]);
};

4. Listen to the message event sent by the client and broadcast when the message is received:

$worker->onMessage = function($connection, $data) use ($worker) {
    // 接收到客户端消息时进行广播
    foreach($worker->connections as $client) {
        $client->send($data); // 广播消息给所有客户端
    }
};

5. Start the Worker process:

Worker::runAll();

The above code snippet demonstrates how to use the Workerman framework to implement the message broadcast function. When a new client connects to the server, the server saves the client connection. When a client sends a message, the server broadcasts the received message to all clients.

The above is a simple example. In actual projects, security, message format and other factors may also need to be considered. Therefore, when actually writing code, it is recommended that you adjust and improve the code according to specific needs.
