Enum Interfaces

Enums can implement interfaces in PHP.

This allows enum cases to share behavior defined in the interface.

Example

interface Labelable {
    public function label(): string;
}

enum Status implements Labelable {
    case Active;
    case Inactive;

    public function label(): string {
        return match($this) {
            Status::Active => "Active User",
            Status::Inactive => "Inactive User"
        };
    }
}

echo Status::Active->label();
