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

Get enum names 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.
