ReflectionEnum::getCases

Returns a list of all cases on an Enum

&reftitle.description; public `array` `ReflectionEnum::getCases`

An Enum may contain zero or more cases. This method retrieves all defined cases, in lexical order (that is, the order they appear in the source code).

&reftitle.parameters; &no.function.parameters;
&reftitle.returnvalues;

An array of Enum reflection objects, one for each case in the Enum. For a Unit Enum, they will all be instances of `ReflectionEnumUnitCase`. For a Backed Enum, they will all be instances of `ReflectionEnumBackedCase`.

### `ReflectionEnum::getCases` example

    <?php
    enum Suit
    {
        case Hearts;
        case Diamonds;
        case Clubs;
        case Spades;
    }

    $rEnum = new ReflectionEnum(Suit::class);

    $cases = $rEnum->getCases();

    foreach ($cases as $rCase) {
        var_dump($rCase->getValue());
    }
    ?>

&example.outputs;

    enum(Suit::Hearts)
    enum(Suit::Diamonds)
