[Native enums](https://php.watch/versions/8.1/enums) is a new PHP 8.1 feature. This feature brings more focus on *what* enums are and *where* we can use them. **Not on PHP 8.1 yet?** Don't worry, before that, enums were emulated by public constants. Some constant lists are already part of your favorite framework, ORM, or utils package for years. Today we look at 5 constant lists that you can use today to replace that `int` or `string` and give it a context.
