On the AWS development blog Jeremy Lindblom has a recent post with a preview of the AWS resource APIs for PHP and the AWS SDK for PHP.
This year is just about over, but we are too excited to wait until the new year to share with you a feature we are developing for the AWS SDK for PHP. We are calling it the AWS Resource APIs for PHP. This feature is maintained as a separate package, but it acts as an extension to Version 3 of the AWS SDK for PHP.
He talks about the new resource objects that contain information to identify what it represented (like a S3 bucket or SQS queue) and includes an example object structure. He shows how to perform actions on the objects and working with collections. He also includes a helpful hint about using the "respondsTo" method on the object to get the methods the object can use.
