How to Get Names of All Enum Cases as an Array of Strings in PHP?

You can get all case names of a PHP enum as an array of strings in the following way:

1. Call the static cases() method on the enum to get an array of all defined cases (in the order of declaration);
2. Use array_column() on the resulting array of enums, and specify the name (public) property as the column key.

For example:

// PHP 8.1+
enum MyEnum
{
    case Foo;
    case Bar;
    case Baz;
}

$enumsArr = MyEnum::cases();
$names = array_column($enumsArr, 'name');

var_dump($names); // ['Foo', 'Bar', 'Baz']

It works the same way for backed enums as well.
