## What it is
The reference PHP package for PSR-3, providing the LoggerInterface and related classes/traits that define a standard logging contract. It is not a logger implementation itself, but the interface libraries use to accept any compatible logger.

## Use cases
- accept any psr-3 compatible logger in my php library
- standard logging interface for php packages
- type-hint a logger without coupling to a specific implementation
- implement a custom logger that works with php frameworks
- swap logging backends in a php application

## When to choose
- you are writing a PHP library or framework that should support any logger
- you want to implement a PSR-3 compliant logger
- you need to type-hint logging without a concrete dependency

## When to avoid
- you need an actual working logger implementation (use Monolog or similar)
- your project does not follow PSR standards

## Facets
- artifact type: library
- maturity: stable
- function: logging
- domain: developer-tools, backend
- platform: php
- tags: psr-3, logger-interface, composer, standards
