anik/amqp

anik/amqp is a php-amqplib wrapper that eases the consumption of RabbitMQ. A painless way of using RabbitMQ.

Note

Previously, the package could be used with Laravel, Laravel Zero, Lumen out of the box. From v2, the Laravel support has been removed. If you are looking for implementation with Laravel, you can use anik/laravel-amqp. If you were using this package with Laravel, and you want to upgrade to Laravel 9, please consider using anik/amqp-to-laravel-amqp if you want to migrate to anik/laravel-amqp later.

Examples

Checkout the repository for example.

Requirements

PHP ^7.2 | ^8.0
PHP-AMQPLib ^3.0

Installation

To install the package, run

composer require anik/amqp

Documentation

For V1: https://medium.com/@sirajul.anik/rabbitmq-for-php-developers-c17cd019a90

Connection

To create an AMQP Connection, you can use

Anik\Amqp\AmqpConnectionFactory::make
Anik\Amqp\AmqpConnectionFactory::makeFromArray

<?php

use Anik\Amqp\AmqpConnectionFactory;
use PhpAmqpLib\Connection\AMQPLazySSLConnection;

$host = '127.0.0.1';
$port = 5672;
$user = 'user';
$password = 'password';
$vhost = '/';
$options = []; // options to be proxied to the amqp connection class
$ofClass = AMQPLazySSLConnection::class;

$connection = AmqpConnectionFactory::make($host, $port, $user, $password, $vhost, $options, $ofClass);
$hosts = [
    [
        'host' => $host,
        'port' => $port,
        'user' => $user,
        'password' => $password,
        'vhost' => $vhost,
    ],
    [
        'host' => $host,
        'port' => $port,
        'user' => $user,
        'password' => $password,
        'vhost' => $vhost,
    ]
];

// With AmqpConnectionFactory::makeFromArray method, you can try to connect to multiple host
$connection = AmqpConnectionFactory::makeFromArray($hosts, $options, $ofClass);

Exchange

Also, there are four specific exchange classes.

Anik\Amqp\Exchanges\Direct for direct exchange.
Anik\Amqp\Exchanges\Fanout for fanout exchange.
Anik\Amqp\Exchanges\Headers for headers exchange.
Anik\Amqp\Exchanges\Topic for topic exchange.

You can still use Anik\Amqp\Exchanges\Exchange base class to create your own exchange.

To instantiate an exchange, you can do like

<?php

use Anik\Amqp\Exchanges\Exchange;
use Anik\Amqp\Exchanges\Fanout;
use Anik\Amqp\Exchanges\Topic;

$exchange = new Exchange('anik.amqp.direct.exchange', Exchange::TYPE_DIRECT);

$exchange = Exchange::make(['name' => 'anik.amqp.direct.exchange', 'type' => Exchange::TYPE_DIRECT]);

$exchange = new Topic('anik.amqp.topic.exchange');

$exchange = Fanout::make(['name' => 'anik.amqp.fanout.exchange']);

When creating an exchange instance with

Exchange::make - name and type keys must be present in the given array.
Topic::make Fanout::make Headers::make Direct::make - name key must be present in the given array.

Anik\Amqp\Exchanges\Exchange contains a few predefined exchange types, you can use them as reference.

TYPE_DIRECT for direct type.
TYPE_TOPIC for topic type.
TYPE_FANOUT for fanout type.
TYPE_HEADERS for headers type.

The Exchange::make method also accepts the following keys when making an exchange instance.

declare Type: bool. Default: false. If you want to declare the exchange.
passive Type: bool. Default: false. If the exchange is passive.
durable Type: bool. Default: true. If the exchange is durable.
auto_delete Type: bool. Default: false. If the exchange should auto delete.
internal Type: bool. Default: false. If the exchange is internal.
no_wait Type: bool. Default: false. If the client should not wait for the server's reply.
arguments Type: array. Default: [].
ticket Type: null | integer. Default: null.

You can also reconfigure the exchange instance using $exchange->reconfigure($options). The $options array accepts the above keys as well.

Also, you can use the following methods to configure your exchange instance.

setName - Accepts: string. The only way to change exchange name after instantiation.
setDeclare - Accepts: bool.
setType - Accepts: bool.
setPassive - Accepts: bool.
setDurable - Accepts: bool.

Queue

To instantiate a queue, you can do like

<?php

use Anik\Amqp\Queues\Queue;

$queue = new Queue('anik.amqp.direct.exchange.queue');

$queue = Queue::make(['name' => 'anik.amqp.direct.exchange.queue']);

When creating a queue instance with

Queue::make - name keys must be present in the given array.

The Queue::make method also accepts the following keys when making a queue instance.

declare Type: bool. Default: false. If you want to declare the queue.
passive Type: bool. Default: false. If the queue is passive.
durable Type: bool. Default: true. If the queue is durable.
exclusive Type: bool. Default: false. If the queue is exclusive.
auto_delete Type: bool. Default: false. If the queue should auto delete.
no_wait Type: bool. Default: false. If the client should not wait for the server's reply.
arguments Type: array. Default: [].
ticket Type: null | integer. Default: null.

You can also reconfigure the queue instance using $queue->reconfigure($options). The $options array accepts the above keys as well.

Also, you can use the following methods to configure your queue instance.

setName - Accepts: string. The only way to change queue name after instantiation.
setDeclare - Accepts: bool.
setType - Accepts: bool.
setPassive - Accepts: bool.
setDurable - Accepts: bool.
setExclusive - Accepts: bool.
setAutoDelete - Accepts: bool.

Qos

To instantiate a Qos, you can do like

<?php

use Anik\Amqp\Qos\Qos;

$prefetchSize = 0;
$prefetchCount = 0;
$global = false;

$qos = new Qos($prefetchSize, $prefetchCount, $global);

$qos = Queue::make(['prefetch_size' => $prefetchSize, 'prefetch_count' => $prefetchCount, 'global' => $global]);

The Qos::make method also accepts the following key when making a qos instance.

prefetch_size Type: int. Default: 0.
prefetch_count Type: int. Default: 0.
global Type: bool. Default: true.

You can also reconfigure the qos instance using $qos->reconfigure($options). The $options array accepts the above keys as well.

Also, you can use the following methods to configure your qos instance.

setPrefetchCount - Accepts: int.
setPrefetchSize - Accepts: int.
setGlobal - Accepts: bool.

Publish/Produce message

To produce/publish messages, you'll need the Anik\Amqp\Producer instance. To instantiate the class

<?php

use Anik\Amqp\Producer;

$producer = new Producer($connection, $channel);

The constructor accepts

$connection Type: PhpAmqpLib\Connection\AbstractConnection. Required.
$channel Type: null | PhpAmqpLib\Channel\AMQPChannel. Optional.

If $channel is not provided or null, class uses the channel from the $connection.

Once the producer class is instantiated, you can set a channel with setChannel. Method accepts PhpAmqpLib\Channel\AMQPChannel instance.

There are three ways to publish messages

Bulk Publish

Producer::publishBatch - to publish multiple messages in bulk.

<?php

use Anik\Amqp\Producer;

(new Producer($connection))->publishBatch($messages, $routingKey, $exchange, $options);

$messages Type: Anik\Amqp\Producible[]. If any of the message is not the type of Producible interface, it'll throw error.
$routingKey Type: string. Routing key. Default '' (empty string).
$exchange Type: null | Anik\Amqp\Exchanges\Exchange.
$options Type: array. Runtime configuration.
- Key exchange - Accepts: array.
  - If you pass null as $exchange, then you must provide a valid configuration through this key to create an exchange under the hood. If you pass $exchange with Exchange instance and $options['exchange'], exchange instance will be reconfigured accordingly with the values available in $options['exchange']. Keys are same as Exchange::make's $options.
- Key publish - Accepts: array.
  - Key mandatory Default false.
  - Key immediate Default false.
  - Key ticket Default null.
  - Key batch_count. Default: 500. To make a batch of X messages before publishing a batch.

Publish

Producer::publish - to publish a single message. Uses Producer::publishBatch under the hood.

<?php

use Anik\Amqp\Producer;

(new Producer($connection))->publish($message, $routingKey, $exchange, $options);

$message Type: Anik\Amqp\Producible.
$routingKey Type: string. Routing key. Default '' (empty string).
$exchange Type: null | Anik\Amqp\Exchanges\Exchange.
$options Type: array. Runtime configuration.
- Key exchange - Accepts: array.
  - If you pass null as $exchange, then you must provide a valid configuration through this key to create an exchange under the hood. If you pass $exchange with Exchange instance and $options['exchange'], exchange instance will be reconfigured accordingly with the values available in $options['exchange']. Keys are same as Exchange::make's $options.
- Key publish - Accepts: array.
  - Key mandatory Default false.
  - Key immediate Default false.
  - Key ticket Default null.

Publish Basic

Producer::publishBasic - to publish a single message using AMQPChannel::basic_publish method.

use Anik\Amqp\Producer;

(new Producer($connection))->publishBasic($message, $routingKey, $exchange, $options);

$message Type: Anik\Amqp\Producible.
$routingKey Type: string. Routing key. Default '' (empty string).
$exchange Type: null | Anik\Amqp\Exchanges\Exchange.
$options Type: array. Runtime configuration.

$msg = new ProducibleMessage('take my message to rabbitmq');

$msg = new ProducibleMessage('take my message to rabbitmq', [
    'delivery_mode' => AMQPMessage::DELIVERY_MODE_PERSISTENT,
]);

$msg = (new ProducibleMessage())->setMessage('take my message to rabbitmq')->setProperties([
    'delivery_mode' => AMQPMessage::DELIVERY_MODE_PERSISTENT,
    'application_headers' => new AMQPTable(['key' => 'value']),
]);

Consumer

To consume messages, you'll need the Anik\Amqp\Consumer instance. To instantiate the class

<?php

use Anik\Amqp\Consumer;

$consumer = new Consumer($connection, $channel, $options);

The constructor accepts

$connection Type: PhpAmqpLib\Connection\AbstractConnection. Required.
$channel Type: null | PhpAmqpLib\Channel\AMQPChannel. Optional.
$options Type: array. Optional. Configurations for consumer.

$msg = new ConsumableMessage(function (ConsumableMessage $message/*, AMQPMessage $original*/) {
    echo $message->getMessageBody() . PHP_EOL;
    echo $message->getRoutingKey() . PHP_EOL;
    $message->ack();
    // Alternatively, $original->ack();

    /** 
     * Method: `decodeMessage` 
     * Returns:
