The AWS SDK for PHP enables developers to build solutions for Amazon Simple Storage Service (Amazon S3), Amazon Elastic Compute Cloud (Amazon EC2), Amazon SimpleDB, and more. With the AWS SDK for PHP, developers can get started in minutes with a single, downloadable package.

The SDK features:

  • AWS PHP Libraries: Build PHP applications on top of APIs that take the complexity out of coding directly against a web service interface. The toolkit provides APIs that hide much of the lower-level implementation.
  • Code Samples: Practical examples for how to use the toolkit to build applications.
  • Documentation: Complete SDK reference documentation with samples demonstrating how to use the SDK.
  • PEAR package: The ability to install the AWS SDK for PHP as a PEAR package.
  • SDK Compatibility Test: Includes both an HTML-based and a CLI-based SDK Compatibility Test that you can run on your server to determine whether or not your PHP environment meets the minimum requirements.

Signing up for Amazon Web Services

Before you can begin, you must sign up for each service you want to use.

To sign up for a service:

  • Go to the home page for the service. You can find a list of services on
  • Click the Sign Up button on the top right corner of the page. If you don't already have an AWS account, you are prompted to create one as part of the sign up process.
  • Follow the on-screen instructions.
  • AWS sends you a confirmation e-mail after the sign-up process is complete. At any time, you can view your current account activity and manage your account by going to and clicking "Your Account".


The source tree for includes the following files and directories:

  • _compatibility_test -- Includes both an HTML-based and a CLI-based SDK Compatibility Test that you can run on your server to determine whether or not your PHP environment meets the minimum requirements.
  • _docs -- Informational documents, the contents of which should be fairly self-explanatory.
  • _samples -- Code samples that you can run out of the box.
  • lib -- Contains any third-party libraries that the SDK depends on. The licenses for these projects will always be Apache 2.0-compatible.
  • services -- Contains the service-specific classes that communicate with AWS. These classes are always prefixed with Amazon.
  • utilities -- Contains any utility-type methods that the SDK uses. Includes extensions to built-in PHP classes, as well as new functionality that is entirely custom. These classes are always prefixed with CF.
  • README -- The document you're reading right now.
  • -- A sample configuration file that should be filled out and renamed to
  • sdk.class.php -- The SDK loader that you would include in your projects. Contains the base functionality that the rest of the SDK depends on.

Minimum Requirements in a nutshell

  • You are at least an intermediate-level PHP developer and have a basic understanding of object-oriented PHP.
  • You have a valid AWS account, and you've already signed up for the services you want to use.
  • The PHP interpreter, version 5.2 or newer. PHP 5.2.17 or 5.3.x is highly recommended for use with the AWS SDK for PHP.
  • The cURL PHP extension (compiled with the OpenSSL libraries for HTTPS support).
  • The ability to read from and write to the file system via file_get_contents() and file_put_contents().

If you're not sure whether your PHP environment meets these requirements, run the SDK Compatibility Test script included in the SDK download.


Via GitHub

Amazon Web Services publishes releases of the AWS SDK for PHP to GitHub, which is a hosted service for Git repositories.

If you're unfamiliar with Git, there are a variety of resources on the net that will help you learn more:

Here's how you would check out the source code from GitHub:

git clone git:// AWSSDKforPHP


Amazon Web Services also publishes releases of the AWS SDK for PHP to a self-hosted PEAR repository.

If you're unfamiliar with how to install PEAR packages, check out Command line installer in the PEAR user guide.

sudo pear channel-discover
sudo pear install aws/sdk


  1. Copy the contents of and add your credentials as instructed in the file.
  2. Move your file to ~/.aws/sdk/
  3. Make sure that getenv('HOME') points to your user directory. If not you'll need to set putenv('HOME=<your-user-directory>').
