What is it?
Amazon's official SDK (Software Development Kit) for using AWS services with the PHP language.
Why did we choose it?
Well, if you want to make use of AWS services from PHP, the official library certainly seems the best way to go!
What do we use it for?
Uploading user artwork submissions to AWS S3, checking our email error queues, and a bunch of other things.
