I believe this should do.

<?php
function get_people($filter=null) {
    include 'connection.php';

    //add code here
    try {
      if ($filter) {
        $sql='SELECT * FROM people WHERE treehouse = 1 ORDER BY last_name DESC'; 
      } else {
        $sql='SELECT * FROM people ORDER BY last_name DESC'; 
      }
      $results = $db->prepare($sql);
      $results->execute();
      return $results->fetchAll(PDO::FETCH_ASSOC);
    } catch(Exception $e) {
      echo "Error: " . $e->getMessage();
    } 
}
