PHP Libraries for Amazon Simple Notification Service

I wanted to开发者_JAVA技巧 start using the Amazon Simple Notification Service (http://aws.amazon.com/sns/), but I have not found any PHP libraries that I can use to access the service. I would rather not create my own library, I wanted to see if anybody has used any PHP libraries for the SNS service, and if they would recommend any.

The AWS SDK for PHP supports Amazon SNS.

Here's an unfinished php client for Amazon SNS

The Zend Framework has libraries for S3, EC2, and SQS so it wouldn't surprise me if the team that built those was working on a more specific library for SNS as well. Maybe Zend's Amazon library will get you part of the way?

SNS is still in Beta, right? That may make it a little tougher to find the library you're looking for.
