[PHP] Identify which function called another

[Lars B. Jensen]

Is there any way, I from one function can identify which other function called 
it, without parameter passing the name manually ?

In code, something like
<?php
    function a() {
        return c();
    }

    function b() {
        return c();
    }

    function c() {
        return 'I got called by'.$name_of_the_function_who_called_me;
    }

    echo b();
?>

where I would like to have function c identify if it was called by function a 
or b
