$_SERVER['PHP_SELF'] and other bits in $_SERVER have the "main" PHP
filename in them.

__FILE__ will always be exactly the file that it's in.

In between, I think you are stuck with the debug_backtrace.

NOTE:
If it's for error logging or error reporting, note that trigger_error
automatically passes in the file/line to the error handler.
