How to publish message with out the loop?

[badmansan]

Hello! I am using bunny to work with RabbitMQ, the code is:

$client = (new Bunny\Client())->connect()->channel();
// ...
$channel->run(function(Message $message, Channel $channel, Client $client) {
	// --> here i need to send a message to MQTT broker;
}, 'hello', '', FALSE, TRUE);

It is infinite loop, so i need to send message and return to loop, is it possible?
