How to Get an Array of All Enum Cases in PHP?

To get all cases of a PHP enum, you can simply call the static cases() method on it:

// PHP 8.1+

This would return an array of all defined enum cases in the order of declaration. For example:

// PHP 8.1+
enum MyEnum
    case Foo;
    case Bar;
    case Baz;

$cases = MyEnum::cases();

var_dump($cases); // [enum(MyEnum::Foo), enum(MyEnum::Bar), enum(MyEnum::Baz)]

echo $cases[0]->name; // 'Foo'

The static cases() method is available on both, pure enums and backed enums, as they both implement the common, internal interface named UnitEnum (which includes the static method cases()).
