Массив iTunes Search

Я использую оболочку, которая позволяет очень просто получить поисковый запрос и преобразовать его в массив.

У меня проблемы с анализом этого массива. Как мне создать цикл foreach (), чтобы получить значения из этого массива?

Это простая функция, которая захватывает поисковый запрос и преобразует его в массив. Print_r () просто показывает мне, что возвращается.

require_once (get_template_directory() . '/Classes/itunes.php');

function itunesSearch() {
$search_term = $_GET['s'];
$results = iTunes::search($search_term, array(
'country' => 'US'
))->results;

print_r($results);

}

Например, допустим, я ищу Адель. Вот массив, который возвращается:

Это то, что я пробовал, и несколько вариантов этого:

    $results_thing = $results['stdClass']['Object'];

foreach ($results_thing as $result) {
echo $result['wrapperType'];

Я получаю ошибку:

Warning: Invalid argument supplied for foreach()
