Build Status

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


This library is a fork of the php-amqplib library.

At The Netcircle we modified that library in order to work with PHP 5.3 Strict.

Also we improved the debug method to increase performance.

We use it daily in prod for sending/consuming 600K + messages per day.


As of November 2011 I retook the development of this library therefore I tagged the previous version of the library here. If you are looking for the old library then use the code on that tag.

If you are going to use it in a new project I advice that you use the current master branch. There are many performance improvements in that branch and I'm adding more and more tests to it.

Besides that the library has been refactored to use PHP 5.3 namespaces. The classes have been split into their separate files and so on. The idea is to make the library easier to test.

To be sure that what you are downloading works™ you can always check the build status of the library on travis-ci.


Get the library source code:

$ git clone git://

This library uses the Symfony default UniversalClassLoader so you will have to run the following command to download it as a submodule:

$ make

Start your RabbitMQ server and run tests:

$ make test


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

Loading Classes

The library uses the Symfony ClassLoader component in order to use a standard way of class loading.

If you want to see how to use the component with this library you can take a look at the file demo/autoload.php:


require_once(__DIR__ . '/../vendor/symfony/Symfony/Component/ClassLoader/UniversalClassLoader.php');

use Symfony\Component\ClassLoader\UniversalClassLoader;

$loader = new UniversalClassLoader();
            'PhpAmqpLib' => __DIR__ . '/..',



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
