We've got a really nice new AWS SDK for PHP. Like our existing .NET and Java toolkits, this one was designed to be a high-quality SDK with comprehensive feature coverage, documentation, and tutorials. The first release supports a large subset of our infrastructure services including the Amazon Elastic Compute Cloud (EC2), the Amazon Simple Storage Service (S3), Amazon CloudFront, Amazon CloudWatch, Amazon SimpleDB, the Amazon Simple Notification Service (SNS), the Amazon Simple Queue Service (SQS), as well as Amazon Identify and Access Management (IAM).
