absolute path of any PHP script?

how do I get the absolute path to any PHP script currently being executed? __FILE__ does not help here, because if I have require( '../bar.php' ) ; in foo.php, __FILE__ in foo.php will contain e. g. 'c:/wwwroot/aaa/bbb/foo.php' (on windows), but in bar.php it will contain '../bar.php' (e. g. the argument passed to require()). I know I could write a function to do this, but surely there must be an easier way I just missed.
