Hi all,
I've been wondering... I'm a big fan of dirname(__FILE__) but  
sometimes I have a situation where I would like to know the path of  
the file where my function is called.
I'll explain:
file_a.php is:
<?php
        include "/path/to/file_b.php";
        do_something();
?>
file_b.php is:
<?php
        function do_something() {
                // I wonder what's the dirname of file_a.php ?
        }
?>

I know this can be done using debug_backtrace but it's not really  
ideal. I was wondering if someone had this situation and solved it in  
some elegant way.

Cheers,

Matt
