ReflectionEnum::getCases — Returns a list of all cases on an Enum

### Description

public ReflectionEnum::getCases(): array

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).

### Parameters

This function has no parameters.

### Return Values

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.

### Examples

Example #1 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());
}
?>`

The above example will output:

    enum(Suit::Hearts)
    enum(Suit::Diamonds)
    enum(Suit::Clubs)
    enum(Suit::Spades)
