If you just want to include files, why go through all that trouble?
Just use include_once() instead of include(), then nest things
appropriately. For example:
In A.php, include_once("B.php");
In B.php, include_once("C.php");
Then, just include_once("A.php") and he will include B, which will in
turn include C. Using include_once() solves your circular problem,
since no file will ever be included more than once.
Of course I could be totally misunderstanding your problem, also.
