Integrating PHP with Databases: Add genres to $item coding challenge

Hi, I have no idea how to solve the code challenge. See my code below.

Thank you

index.php 
<?php

include "helper.php";

/*
 * helper contains the following variables:
 * $item is an array that contains details about the library item
 * $results is a PDOstatement object with our genre results.
 */
 while ($row = $results->fetch(PDO::FETCH_ASSOC)) {
        $item["genres"][] = $row;
    }

Use the following code it should work....

// use while loop as you do.. while($row = $results->fetch(PDO::FETCH_ASSOC)) { // genres array with genre_id Key and genre value added to it. $item["genres"][$row["genre_id"]] = $row["genre"]; }

Should there be only one key and one value for each row in the associative array? Why are two keys returned for each row?
