Enumerations
Basic Enumerations
Enumerations are a restricting layer on top of classes and class constants, intended to provide a way to define a closed set of possible values for a type.
<?php
enum Suit
{
case Hearts;
case Diamonds;
case Clubs;
case Spades;
}
function do_stuff(Suit $s)
{
// ...
}
do_stuff(Suit::Spades);
?>
For a full discussion, see the Enumerations chapter.
Casting
If an enum is converted to an object, it is not
modified. If an enum is converted to an array,
an array with a single name key (for Pure enums) or
an array with both name and value keys
(for Backed enums) is created. All other cast types will result in an error.
