[PHP-NOTES] note 130472 added to unitenum.cases

The Enum documentation says, "if a Backed Enum is serialized to JSON, it will be represented by its scalar value only, in the appropriate type."

This means you can easily get a backed Enum's values for use in a JSON document using only the BackedEnum::cases() method:

<?php
enum Suits: string {
    case Hearts = 'Heart';
    case Diamonds = 'Diamond';
    case Clubs = 'Spade';
    case Spades = 'Club';
}
echo json_encode(Suits::cases());
?>

Results in this output:

["Heart","Diamond","Spade","Club"]
