## What it is
A small PHP library providing an Enum base class, inspired by SplEnum, for PHP versions lacking native enums. It lets developers define enumerable constants as typed objects usable as parameter/return types with helper methods like from(), values(), and equals().

## Use cases
- use enums as parameter and return types in PHP
- get a list of all possible enum values
- compare enum instances for equality
- create enum instances from dynamic values
- add methods to enum types

## When to choose
- you are on PHP < 8.1 and need enum-like typed constants
- you want SplEnum behavior without installing a C extension
- you need enums with methods and type-hintable instances

## When to avoid
- you are on PHP 8.1+ where native enums are built in
- you only need simple class constants
- you need a heavily developed actively evolving library

## Facets
- artifact type: library
- maturity: maintenance
- function: type-system, serialization
- domain: programming-languages, developer-tools
- platform: php
- tags: enum, spl-enum, value-objects, composer-package
