Hello Jordan, thanks for the reply. When I read you, I have the feeling
that you are a little angry about my question, please dont.

It is a very honest question, that do belong to the internals, because if
PHP does not have a way to do it, I would like to think a way to do it
(despite the fact someone believes is useful or not, it is just me).

So again, thanks!, dont get mad :D, and I will come back later on this
topic, in a more clear way, maybe I am not expressing myself clearly.

Regards
