How to get user-id or AWS account id via AWS PHP SDK

Question

Is there anyway to get UserId or a.k.a. AWS Account ID?

I have checked the documentation but could not locate (...or probably it doesn't exists...) a method call which returns the UserId.

Answer 1

Sort of. There's no way to get it without creating a resource. Many resources have an ARN associated with it. You can extract the Account ID from the ARN, but you'd have to create a resource first.
