Answer Source

I believe that you can only do

global $f_;

As the [$id] is an element of a variable, I am not aware you can only global 1 element. If you want to ONLY pass $f_[$id] you could pass it as a reference

function dothis($value)
   $value = '';//something new

and that will only the address for that single element.
