Which file called the function?

["Christoph Boget" <jcboget@xxxxxxxxx>]

Let's say I have the following 3 files

global.php
<?
  function myFunc() { echo __FILE__; }
?>

one.php
<?
  include( 'global.php' );
  echo 'You are in file: ';
  myFunc();
?>

two.php
<?
  include( 'global.php' );
  echo 'You are in file: ';
  myFunc();
?>

In each case, what is echoed out for __FILE__ is global.php.  Apart from
analyzing the debug_backtrace array, is there any way that myFunc() would
display "one.php" and "two.php" respectively?

thnx,
Christoph
