Subject: [PHP] Need help with auto_prepend_file

What you can do is check on some constant that you define the first
time the file is included. The auto prepended file will then look
something like:

--- Pseudo code ---

- if constant A is not defined
  --  define constant A
  --  your code

--- End of Pseudo code ---

This will make sure function, variables and/or constants will only
be defined once.
