关于workerman群发消息的一个小疑问

  $worker = new Worker("websocket://127.0.0.1:9952");

  $worker->count = 2;

$worker->onMessage = function (TcpConnection $connection, $buffer) {
    // 这里拿到的是当前worker进程中的所有连接信息
     $connections = $connection->worker->connections;

        $workerId = $connection->worker->id;

        foreach ($connections as $connection) {
            $connection->send("worker id: " . $workerId . " connection id = " . $connection->id . " buffer: " . $buffer);
        }
}
