	/**
	 * @var Producer
	 */
	private $testProducer;

Consuming messages

Your consumer callback has to return a confirmation that particular message has been acknowledges (or different states - unack, reject).

TestConsumer.php

<?php

declare(strict_types=1);

use Bunny\Message;
use Gamee\RabbitMQ\Consumer\IConsumer;

final class TestConsumer implements IConsumer
{

	public function consume(Message $message): int
	{
		$messageData = json_decode($message->content);

		$headers = $message->headers;

		/**
		 * @todo Some logic here...
		 */

		return IConsumer::MESSAGE_ACK; // Or ::MESSAGE_NACK || ::MESSAGE_REJECT
	}

}

Running a consumer trough CLI

There are two consumer commands prepared. rabbitmq:consumer wiil consume messages for specified amount of time (in seconds). Following command wiil be consuming messages for one hour:

php index.php rabbitmq:consumer testConsumer 3600

rabbitmq:staticConsumer will consume particular amount of messages. Following example will consume just 20 messages:

php index.php rabbitmq:staticConsumer testConsumer 20
