PHP SDK for OpenStack/Rackspace APIs
IMPORTANT NOTE: With release 1.3, all of the file extensions have been changed from
.incto.php. This means that any existing code must be edited to use this new version.
ANOTHER IMPORTANT NOTE: the working branch (soon to be release 1.5) has been substantially reorganized around namespaces and all of the file locations/names have been changed.
See the COPYING file for license and copyright information.
For other SDKs, see http://developer.rackspace.com
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).
See the Release Notes for what has changed in the latest release(s).
See the php-opencloud wiki for incidental notes mostly aimed at developers who are working on the SDK (and not developers working with the SDK).
Visit https://github.com/rackspace/php-opencloud/tags to see tagged releases that you can download.
You can download the master branch using the GitHub "ZIP" button, above. However, this has the latest code and may not be as stable as the tagged branches.
Your feedback is appreciated! If you have specific problems or bugs with the php-opencloud language bindings, please file an issue via Github.
For general feedback and support requests, send an email to:
You can also find assistance via IRC on #rackspace at freenode.net.
To sign up for a Rackspace Cloud account, go to http://www.rackspace.com/cloud and follow the prompts.
If you are working with an OpenStack deployment, you can find more information at http://www.openstack.org.
We are not able to test and validate every possible combination of PHP versions and supporting libraries, but here's our recommended minimum version list:
- PHP 5.3 (note: Travis validates against 5.4 and 5.5 as well)
- CURL extensions to PHP
In the .zip or .tar file in which you received the library, everything under
the lib/ directory should be installed in a location that is accessible. If you're not using a dependency manager like Composer, you will have to register the OpenCloud namespace for your app to use:
// Define the path to the library
$libraryPath = '/path/to/php-opencloud';
// Include the autoloader
require_once $libraryPath . '/Autoload.php';
// Register the root OpenCloud namespace
$classLoader = new SplClassLoader('OpenCloud', $libraryPath . '/lib');
$classLoader->register();
Once the OpenCloud namespace is registered, you will be able to access all functionality by referencing the class's namespace (in full PSR-0 compliance). For more information about namespaces, check out PHP's documentation.
If you'd like to contribute to php-opencloud, see the HACKING.md file in the root directory.
The file docs/quickref.md contains a Quick Reference guide to the php-opencloud library.
The source for the "Getting Started with php-opencloud" document (the user guide) starts in docs/userguide/index.md.
There is a complete (auto-generated) API reference manual in the docs/api directory. Start with docs/api/index.html.
See the HOWTO.md file for instructions on regenerating the documentation and running tests.
See the smoketest.php file for some simple, working examples. This is a test we run before builds to ensure that all the core functionality is still working after code changes.
The samples/ directory has a collection of tested, working sample code. Note that these may create objects in your cloud for which you could be charged.
