Please check this for viability...
# the directory ./includes/ contains
#       - get_my_info.php containing the function get_my_info()
#       - and numerous other functions which may or may not be
#         needed by any particular file
# include at the top of each page

# function_do(FunctionName,FunctionVariables)
function function_do($f_name,$f_string){
        if (!function_exists($f_name)) {
                # function doesn't exists, needs to be included
        } else {
                # function already exists, no action required
        return $return;




# when we need to run a function
# instead of...
$my_info = get_my_info('name','account');
# we would do...
$my_info = function_do("get_my_info","'name','account'");

This would check to see if the function was already called and included, and if
not, include, then run and return the result.  this would avoid having to
include explicitly any files containing functions on any page as they would all
be loaded dynamically.

Am I groking this correctly?
