How do I make it work?

var_dump is not working here for some reason so I cannot even check if the array structure is correct.

index.php 
<?php

include "helper.php";

/*
 * helper contains the following variables:
 * $item is an array that contains details about the library item
 * $results is a PDOstatement object with our genre results.
 */

$genres = array();

while($row = $results->fetch(PDO::FETCH_ASSOC)) {
  $genres[$row['genre_id']][] = $row['genre'];

  $item['genres'] = $genres;

  var_dump($genres);
}
