## What it is
The official PHP-FIG repository holding the PSR-11 Container Interface, a set of PHP interfaces describing dependency injection containers. It provides only abstractions, not an implementation, so containers can be interoperable across frameworks.

## Use cases
- standardize dependency injection container interfaces in a PHP framework
- make my DI container PSR-11 compliant
- type-hint against a container interface instead of a concrete implementation
- swap DI containers without changing application code
- build interoperable PHP libraries that accept any PSR-11 container

## When to choose
- you are building a PHP framework or library that should work with any compliant DI container
- you want to make your container implementation PSR-11 compatible
- you need a stable, FIG-standardized interface to type-hint against

## When to avoid
- you need an actual working dependency injection container implementation
- your project does not use PHP
- you want features like auto-wiring or configuration out of the box

## Facets
- artifact type: library
- maturity: stable
- function: middleware, developer-tools
- domain: developer-tools, web-development, backend
- platform: php
- tags: psr-11, dependency-injection, container-interface, php-fig, abstraction
