Only primitive types are supported: `string`, `int`, `float`, `bool` and `void` (for return type). **Nullable parameter types are fully supported** for all primitive types (`?string`, `?int`, `?float`, `?bool`).

-The directive supports various value types including strings, integers, booleans, floats, and iota constants. When using `iota`, the generator automatically assigns sequential values (0, 1, 2, etc.). Global constants become available in your PHP code as global constants, while class constants are scoped to their respective classes. When using integers, different possible notation (binary, hex, octal) are supported and dumped as is in the PHP stub file.

 You can use constants just like you are used to in the Go code. For example, let's take the `repeat_this()` function we declared earlier and change the last argument to an integer:

 > In this example, we don't perform any error handling, but you should always check that pointers are not `nil` and that the data is valid before using it in your Go functions.
