PHP Enums
summary
PHP 8.1 introduces true enumerated types that replace magic constants with a strict type you can use as parameter, return and property types; two flavors exist: unit enums (no values) and backed enums (string or int values) with automatic .name and .value, static and instance methods, cases() to list members and from/tryFrom to convert DB or API values back; enums are final (no extension), disallow properties, require PHP 8.1 and Composer 2.1 for autoloading, and require adapters for ORMs like Doctrine when persisting.
