Using While Loop - Error says must use while loop

I think I have this correct, but the error I get says I need to use a while loop. As you can see I am using a while loop. Not sure what else to check. Any help would be appreciated.

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.
 */

while ($r = $results->fetch(PDO::FETCH_ASSOC)) {
  $item["genres"] = [$r["genre_id"]=>$r["genre"]];
}

Okay, I figured out the problem.

This code: $item["genres"] = [$r["genre_id"]=>$r["genre"]]; was overwriting the value inside the "genres" array. What I needed to do was add a value inside the associative array with this code: $item["genres"] [$r["genre_id"]]=$r["genre"]];

Not sure why the error showed not using a while loop.
