Using Version 3 of the AWS SDK for PHP

Using Version 3 of the AWS SDK for PHP

Amazon Web Services (AWS) offers a broad set of global compute, storage, database, analytics, application, and deployment services that can help PHP developers build scalable applications in the cloud. These services provide APIs that allow you to control all of your resources programmatically, even through your PHP code. Let's talk about how to use Version 3 of the open source AWS SDK for PHP (built on the Guzzle library and PSR-7) to control your AWS resources and use the AWS services from within your applications.
