 the refernces side effects are related to the array pointer only. the code
 is not using any array pointer. additionally the foreach loop iterates
 over a copy which means this is a new array, not $categories any longer
 (you just quoted that as well).

 Please stop guessing, you are mixing things. Using $array[$index] is not
 using the arrays pointer. Learn more about array pointers in php here:
 http://php.net/manual/en/function.current.php I hope that helps you to
 better understand what an internal array pointer is.

 So please make a proof.
