Send WsServer message from server.
I have gone throught Chat tutorial.
Everything is working for me. But all messages are sending via browser.

My server looks like this:
$server = IoServer::factory(new HttpServer(new WsServer(new Chat())), 8080);
$server->run();

How can I get reference to WsServer from other scripts? For example I have cron job which gather system messages from DB and should send this messages to all clients in the Chat. This code should be executed in php on the server. Is there any possibility to do this? Thank you!
