$rsb
    ->from(array('firstName', 'lastName'))
        ->within($person)
    ->using(function ($firstName, $lastName) { return sprintf("%s %s", $firstName, $lastName); })
        ->on(array('firstName', 'lastName'))
    ->to('fullName')
        ->within($contact);
    ->from('phoneNumber')
        ->within($person)
    ->to('phoneNumber')
        ->within($contact)
    ->build()

Below indentation is more legible:

$rsb
    ->from(array('firstName', 'lastName'))->within($person)
        ->using(function ($firstName, $lastName) { return sprintf("%s %s", $firstName, $lastName); })
        ->on(array('firstName', 'lastName'))
    ->to('fullName')->within($contact);
    ->from('phoneNumber')->within($person)
    ->to('phoneNumber')->within($contact)
    ->build()
