OK. The way I read it was:

> Say you have defined a variable $var in your main script.

> Now in a function you access it using:
> global $var;

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


> But you want to set it to null inside the function.

The above means "you want to unset global variable $var / set it
to null"


> DO: $var = null;
> DONT DO: unset($var);

"Because the 2nd way removes the variable from current (function) namespace"


> and it is no longer globally available.

"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.
