PHP SDK for OpenStack/Rackspace APIs

Latest Stable Version Travis CI Total Downloads

Our official documentation is now available on For SDKs in different languages, see

The PHP SDK should work with most OpenStack-based cloud deployments, though it specifically targets the Rackspace public cloud. In general, whenever a Rackspace deployment is substantially different than a pure OpenStack one, a separate Rackspace subclass is provided so that you can still use the SDK with a pure OpenStack instance (for example, see the OpenStack class (for OpenStack) and the Rackspace subclass).


  • PHP >=5.3.3
  • cURL extension for PHP


You must install this library through Composer:

# Install Composer
curl -sS | php

# Require php-opencloud as a dependency
php composer.phar require rackspace/php-opencloud

Once you have installed the library, you will need to load Composer's autoloader (which registers all the required namespaces). To do this, place the following line of PHP code at the top of your application's PHP files:

require 'vendor/autoload.php';

Note: this assumes your application's PHP files are located in the same folder as vendor/. If your files are located elsewhere, please supply the path to vendor/autoload.php in the require statement above.

And you're ready to go!

You can also check out the Getting Started guide for a quick tutorial.

Alternatively, if you would like to fork or clone the repository into a directory (to work and submit pull requests), you will need to execute:

php composer.phar install

Instead of the require command. You can also specify the --no-dev option if you do not want to install phpDocumentor (which has lots of vendor folders).
