How to use Square API to get the items sold data in a business day from the Order Object and insert it into MySQL database

So right now I am trying to get the different items sold per day from the Order API from Square. However, I do not know how to get the name of the item sold, the catalog_id of it and the quantity sold into a three different array for me to insert it into MySQL db. I have replaced my accessToken and locationId as 'XXXX'.

<?php
require_once(__DIR__ . '/vendor/autoload.php');

use Square\SquareClient;
use Square\Exceptions\ApiException;
use Square\Http\ApiResponse;
use Square\Models\ListLocationsResponse;
use Square\Environment;
use Square\Orders;

$client = new SquareClient([
    'accessToken' => 'XXXX',
    'environment' => Environment::PRODUCTION,
]);

SquareConnect\Configuration::getDefaultConfiguration()->setAccessToken('XXXX');

$body = new Square\Models\SearchOrdersRequest;
$ordersApi = $client->getOrdersApi();
$apiResponse = $ordersApi->searchOrders($body);

$location_ids = ['XXXX'];
$created_at = new \Square\Models\TimeRange();
$created_at->setStartAt('2021-04-10T00:00:00+08:00');
$created_at->setEndAt('2021-04-10T23:59:59+08:00'); 

$date_time_filter = new \Square\Models\SearchOrdersDateTimeFilter();
$date_time_filter->setCreatedAt($created_at);

$filter = new \Square\Models\SearchOrdersFilter();
$filter->setDateTimeFilter($date_time_filter);

$sort = new \Square\Models\SearchOrdersSort('CREATED_AT');
$sort->setSortOrder('DESC');

$query = new \Square\Models\SearchOrdersQuery();
$query->setFilter($filter);
$query->setSort($sort);

$body = new \Square\Models\SearchOrdersRequest();
$body->setLocationIds($location_ids);
$body->setQuery($query);
$body->setLimit(500);
$body->setReturnEntries(false);

$api_response = $client->getOrdersApi()->searchOrders($body);

if ($api_response->isSuccess()) {
    $result = $api_response->getResult();
    //print_r($result);
    var_export($result);
} else {
    $errors = $api_response->getErrors();
}

?>

This is the output of the above code :
