30,617 PointsHow to add an item to an array
I am struggling to add an item to an array (at least I think that is what the question is asking). I have this so far, but I am unsure how to do it. Please can anyone explain what I am doing wrong.
while ($row = $results->fetch(PDO::FETCH_ASSOC)) {
$item[$row["genres"]][] = [genre_id=>genre];
}
<?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["genres"]][] = [genre_id=>genre];
}

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