I suppose the above text was clear and requires no translation.

The above means "you want to unset global variable $var / set it
to null"
> DO: $var = null;
> DONT DO: unset($var);

"You do not have acces to the global variable from current (function) scope."

PS.: The fact that English is not my native language is probably influencing
the way that I read it.
