            'host'                => 'localhost',

            'password'            => 'password',
            'vhost'               => '/',
            'exchange'            => 'amq.topic',
            'exchange_type'       => 'topic',
            'consumer_tag'        => 'consumer',

Publishing a message

Push message with routing key

    Amqp::publish('routing-key', 'message');

Push message with routing key and create queue

    Amqp::publish('routing-key', 'message' , ['queue' => 'queue-name']);

Push message with routing key and overwrite properties

    Amqp::publish('routing-key', 'message' , ['exchange' => 'amq.direct']);

Consuming messages

Consume messages, acknowledge and stop when no message is left

Amqp::consume('queue-name', function ($message, $resolver) {

   var_dump($message->body);

   $resolver->acknowledge($message);

   $resolver->stopWhenProcessed();

});

Consume messages forever

Amqp::consume('queue-name', function ($message, $resolver) {

   var_dump($message->body);

   $resolver->acknowledge($message);

});

Consume messages, with custom settings

Amqp::consume('queue-name', function ($message, $resolver) {

   var_dump($message->body);

   $resolver->acknowledge($message);

}, [
  'timeout' => 2,
  'vhost'   => 'vhost3'
]);

Fanout example

Publishing a message

\Amqp::publish('', 'message' , [
    'exchange_type' => 'fanout',
    'exchange' => 'amq.fanout',
]);

Consuming messages

\Amqp::consume('', function ($message, $resolver) {
    var_dump($message->body);
    $resolver->acknowledge($message);
}, [
    'exchange' => 'amq.fanout',
