## What it is
PHP-FIG's PSR-17 interfaces describing factories for creating PSR-7 HTTP message objects (requests, responses, URIs, streams, uploaded files). It provides only interfaces, not an implementation, enabling interoperability between HTTP libraries and frameworks.

## Use cases
- create PSR-7 HTTP messages without coupling to a specific implementation
- write framework-agnostic PHP middleware that needs request/response factories
- swap HTTP message implementations in a PHP application via a standard interface
- build reusable PHP packages that construct HTTP requests and responses
- type-hint against a standard HTTP factory in dependency injection containers

## When to choose
- you are building PHP libraries or middleware that must interoperate with any PSR-7 implementation
- you need standard interfaces to inject HTTP message factories into your components
- you are implementing PSR-17 in your own HTTP message library

## When to avoid
- you need an actual working HTTP factory implementation rather than interfaces
- your project does not use PSR-7 HTTP messages
- you are not working in PHP

## Facets
- artifact type: library
- maturity: stable
- function: http-client, http-server, middleware
- domain: web-development, backend, apis
- platform: php
