## What it is
PHP-DI is a dependency injection container for PHP that emphasizes practicality, autowiring, and expressive PHP-based configuration. It is framework-agnostic, PSR-11 compliant, and supports container compilation for production performance.

## Use cases
- manage dependency injection in a PHP application
- autowire classes from constructor type-hints
- bind interfaces to implementations in a service container
- replace Pimple or another PSR-11 container
- configure services with PHP-based definitions instead of YAML or XML
- integrate a DI container with Slim or Symfony

## When to choose
- you want a PSR-11 compliant container with zero-config autowiring
- you prefer configuration written in PHP with IDE autocompletion and static analysis
- you need a framework-agnostic container that scales from small apps to modular systems
- you want compiled containers for optimal production performance

## When to avoid
- your framework already ships with its own DI container you are happy with
- you need dependency injection in a non-PHP project
- you are on PHP below 8.0 (PHP-DI 7 requirement)

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