The issue requests a 'PHP server description' for the react s3 uploader component, but the project is a React component that uploads to S3 directly from the browser. It is unclear what exact documentation or server code is needed—possible a usage example with a PHP backend? The issue is from 2017 with no comments or PRs, so the scope is ambiguous. A contributor should ask for clarification from maintainers regarding the expected content and whether this is within the project's scope. If accepted, the contributor could add a section in the README or a separate doc showing how to integrate with a PHP server for handling uploads.
