The UnitEnum interface
(PHP 8 >= 8.1.0)
Introduction
The UnitEnum interface is automatically applied to all enumerations by the engine. It may not be implemented by user-defined classes. Enumerations may not override its methods, as default implementations are provided by the engine. It is available only for type checks.
