How to sort in RedBeanPHP?

Question

PHP

Good afternoon.
In stock request:

$answers = R::find('questionnaire', 'date = ?', array($date));

After which there is a loop where we use a many-to-one relationship to take values ​​from another table:

foreach ($answers as $answer) {

                $l_name = $answer->person['last_name'];
                $f_name = $answer->person['first_name'];
....
}

And then we display everything we need in the table:

<td width="25%"><? echo $l_name . ' ' . $f_name; ?></td>

In general, from the questionnaire table by id we get the last name and first name of the person from the person table.
How can I sort people alphabetically, and is it possible?
