Find a root class of a class

[giacomomasseron]

Hi,
I need to find the root class of a class.
I tried to use AI, but the code does not work.

class BaseClass {}

class Parent extends BaseClass {}

class Child extends Parent {}

I would need something like:

$root = findRoot('Child'); // It should return "BaseClass"

You can either use php-src builtin reflection https://www.php.net/manual/en/reflectionclass.getparentclass.php

or https://github.com/Roave/BetterReflection in case you do not want to load/execute code
