class SubclassComparator
{
    public function isASubClass($object, string $parentClass)
    {
        return is_subclass_of($object, $parentClass);

Due to PHP Bug #53727, is_subclass_of might return inconsistent results on some PHP versions if $parentClass can be an interface. If so, you could instead use ReflectionClass::implementsInterface.

    }

    public function isASubClassButNoSameClass($object, string $parentClass)
    {
        return $this->isASubClass($object, $parentClass) && $this->getObjectClass($object) !== $parentClass;
    }
