All Enum Cases

<?php

enum e: string {
    case A = 1;
    case B = 2;
    case C = 3;
}

print_r(e::cases());
print_r(array_column(e::cases(), 'value'));
/**
Array
(
    [0] => 1
    [1] => 2
    [2] => 3
)
*/
print_r(array_column(e::cases(), 'name'));
/**
Array
(
    [0] => A
    [1] => B
    [2] => C
)
*/
?>

One convenient aspect of enumerations is that they come with a full list of their cases. Call the ::cases() on any enumeration to get the full list of elements.

Then, convert this list into their scalar representation, if any, by calling array_column, with the public property value.

And it always works with the name property, to collect the names of the cases.
