Kinda, but not really.

If you want to do this, you've got to stuff it all in one function, like
so:

function dunno($mandatory, $optional1 = NULL, $opt2 = NULL){
        if (NULL === $optional1){
                // behave, as if only $mandatory is set
                echo 'mandatory is: ' . $mandatory;
                return;
        }
        if (NULL === $optional2){
                // behave, as if $man. and $opt1 have set
                echo 'mand is : ' . $mandatory;
                echo 'opt1 is : ' . $optional1;
                return;
        }
        // neither $opt1 nor $opt2 are null
        echo 'mand is : ' . $mandatory;
        echo 'opt1 is : ' . $optional1;
        echo 'opt2 is : ' . $opt2;
        return;
}
