You might want to re-think how you handle the globals in the first place.

Since all global variables are stored in the $_GLOBALS super array, 
why don't you either reference the global variables as an index of 
that array ($_GLOBALS['variable_name']) or use the extract() function 
at the start of each function to get variable names?
