How to actively push messages

1. You can use a timer to push data at regular intervals

   
   use Workerman\Worker;
   use Workerman\Timer;
   use Workerman\Connection\TcpConnection;
   require_once __DIR__ . '/vendor/autoload.php';

$worker = new Worker('websocket://0.0.0.0:1234');
// Push data to clients at regular intervals after the process starts
$worker->onWorkerStart = function($worker){
Timer::add(1, function()use($worker){
foreach($worker->connections as $connection) {
$connection->send('hello');
}
});
};
Worker::runAll();

2. Notify Workerman to push data when an event occurs in another project
