thanks all. I discovered:

$settings->$str();

worked. i only thought it out without actually trying it beforehand. (Maybe, that's partly because i came from a background in a strongly typed language where some things don't work)

You can call a dynamic method name:

echo $settings->{$str}(); // or $settings->$str();
