Steps Used for Sorting the Items
Step 1: Create an Associative Array for Sorting
Instead of $output being a simple indexed array, we will change this to an associative array with the key being the ID and the value being the item Title.
$sort = $item["title"];
$output[$id] = $sort;
Step 2: Sort the Array by Value and Return Only the Keys
asort($output);
return array_keys($output);
Step 3: Trim "The ", "A ", "An " from the beginning of the title
$sort = ltrim($sort,"The ");
$sort = ltrim($sort,"A ");
$sort = ltrim($sort,"An ");
Step 4: Sort the Full Catalog
To do this we will need to remove the early return from the function which was bypassing the sort. Instead, we will combine the two category conditionals. Either $category should be null (in this case we use every item) OR $category should match the item category.
if ($category == null OR strtolower($category) == strtolower($item["category"])) {
