----------------------------------------

Your environment meets the minimum requirements for using the AWS SDK for PHP!

* The OpenSSL extension is installed. This will allow you to use CloudFront Private URLs and decrypt Windows instance passwords.

* The Zlib extension is installed. The SDK will automatically leverage the compression capabilities of Zlib.

* Storage types available for response caching: The file system

----------------------------------------

Bottom Line: Yes, you can!
Your PHP environment is ready to go! There are a couple of minor features that you won't be able to take advantage of, but nothing that's a show-stopper.
