Build Status

This library is a pure PHP implementation of the AMQP protocol. It's been tested against RabbitMQ.

Requirements: PHP 5.3 due to the use of namespaces.

The library was used for the PHP examples of RabbitMQ in Action and the official RabbitMQ tutorials.


Since version 2.0 this library uses AMQP 0.9.1 by default. You shouldn't need to change your code, but test before upgrading.

Supported RabbitMQ Extensions

Since the library uses AMQP 0.9.1 we added support for the following RabbitMQ extensions:

  • Exchange to Exchange Bindings
  • Basic Nack
  • Publisher Confirms
  • Consumer Cancel Notify

Extensions that modify existing methods like alternate exchanges are also supported.


Add a composer.json file to your project:

  "require": {
      "videlalvaro/php-amqplib": "v2.2.2"

Then provided you have composer installed, you can run the following command:

$ composer.phar install

That will fetch the library and its dependencies inside your vendor folder. Then you can add the following to your .php files in order to use the library

require_once __DIR__.'/vendor/autoload.php';

Then you need to use the relevant classes, for example:

use PhpAmqpLib\Connection\AMQPConnection;
use PhpAmqpLib\Message\AMQPMessage;


With RabbitMQ running open two Terminals and on the first one execute the following commands to start the consumer:

$ cd php-amqplib/demo
$ php amqp_consumer.php

Then on the other Terminal do:

$ cd php-amqplib/demo
$ php amqp_publisher.php some text to publish

You should see the message arriving to the process on the other Terminal

Then to stop the consumer, send to it the quit message:

$ php amqp_publisher.php quit

If you need to listen to the sockets used to connect to RabbitMQ then see the example in the non blocking consumer.

$ php amqp_consumer_non_blocking.php


To not repeat ourselves, if you want to learn more about this library, please refer to the official RabbitMQ tutorials.

More Examples

  • amqp_ha_consumer.php: demos the use of mirrored queues
  • amqp_consumer_exclusive.php and amqp_publisher_exclusive.php: demos fanout exchanges using exclusive queues.
  • amqp_consumer_fanout_{1,2}.php and amqp_publisher_fanout.php: demos fanout exchanges with named queues.
  • basic_get.php: demos obtaining messages from the queues by using the basic get AMQP call.

Batch Publishing

Let's say you have a process that generates a bunch of messages that are going to be published to the same exchange using the same routing_key and options like mandatory. Then you could make use of the batch_basic_publish library feature. You can batch messages like this:

$msg = new AMQPMessage($msg_body);
$ch->batch_basic_publish($msg, $exchange);

$msg2 = new AMQPMessage($msg_body);
$ch->batch_basic_publish($msg2, $exchange);

and then send the batch like this:


When do we publish the message batch?

Let's say our program needs to read from a file and then publish one message per line. Depending on the message size, you will have to decide when it's better to send the batch. You could send it every 50 messages, or every hundred. That's up to you.

Optimized Message Publishing

Another way to speed up your message publishing is by reusing the AMQPMessage message instances. You can create your new message like this:

$properties = array('content_type' => 'text/plain', 'delivery_mode' => 2);
$msg = new AMQPMessage($body, $properties);
$ch->basic_publish($msg, $exchange);

Now let's say that while you want to change the message body for future messages, you will keep the same properties, that is, your messages will still be text/plain and the delivery_mode will still be 2. If you create a new AMQPMessage instance for every published message, then those properties would have to be re-encoded in the AMQP binary format. You could avoid all that by just reusing the AMQPMessage and then resetting the message body like this:

$ch->basic_publish($msg, $exchange);


If you want to know what's going on at a protocol level then add the following constant to your code:

define('AMQP_DEBUG', true);

... more code



To run the publishing/consume benchmark type:

$ make benchmark


To successfully run the tests you need to first setup the test user and test virtual host.

You can do that by running the following commands after starting RabbitMQ:

$ rabbitmqctl add_vhost phpamqplib_testbed
$ rabbitmqctl add_user phpamqplib phpamqplib_password
$ rabbitmqctl set_permissions -p phpamqplib_testbed phpamqplib ".*" ".*" ".*"

Once your environment is set up you can run your tests like this:

$ make test

Using AMQP 0.8

If you still want to use the old version of the protcol then you can do it by settings the following constant in your configuration code:

define('AMQP_PROTOCOL', '0.8');

The default value is '0.9.1'.
