13,659 PointsFetching in a While Loop
Challenge: $item is an array that contains details about the media item. $results is a PDOstatement object with our genre results. Fetch the associative array of $results to loop through, and add an additional "genres" array element to $item. This "genres" element should be an internal associative array with the key of genre_id and the value of genre.
I'm having a hard time understanding what I'm supposed to be doing, I thought I was doing it correctly but it's telling me that I'm not adding anything to genres
<?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)){
$item[$row["genre_id"]] [] = [$row["genre"]];
}

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