  What would the scope of this variable be? If it is global
  (as in PHP engine global) then the solution would not work
  in an shared environment (and it would not be practical
  for multiple applications anyway).

  Ideally, there would be one copy of the variable per
  application, but we need to somehow define what application is.

  I think that the best approach would be to introduce a new
  php configuration option, something like "application_name",
  and that would then define security for these kinds of
  things (naturally, you won't be able to change this one from
  the script :).
