I would not use the bindFunc functions, they are not meant for these kind of things.
I recommend to use a FUSE model.
Just add a class named Model_Person (extends SimpleModel) docs: http://www.redbeanphp.com/models
Now add a method called getDisplayName() or something, inside this method you do something like:
public function getDisplayName() {
return $this->bean->firstName . ' ' . $this->bean->lastName;
}
Now you can do this:
$person = R::load('person', $id);
echo $person->getDisplayName();
and it will show the full name...
Hope this helps, cheers
