The BackedEnum interface

(PHP 8 >= 8.1.0)


The BackedEnum interface is automatically applied to backed 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.

Sommaire de l'Interface

interface BackedEnum extends UnitEnum {
/* Méthodes */
public static from(int|string $value): static
public static tryFrom(int|string $value): ?static
/* Méthodes héritées */
public static UnitEnum::cases(): array
