Question

我正在使用一个包装器，它可以非常简单地获取搜索词并将其转换为数组。

我在解析此数组时遇到问题。如何创建foreach（）循环以从此数组中获取值？

这是抓取搜索词并转换为数组的简单函数。 print_r（）只显示返回的内容。：

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);

}

例如，让我们说我搜索阿黛尔。这是要返回的数组：

这是我尝试过的，以及其中的几种变体：

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

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

我收到错误：

Warning: Invalid argument supplied for foreach()

Answer 1

假设 $ results 包含上面提供的数组。然后获取'wrapperType'的代码......

foreach($results as $result) {
$wrapper_type = $result->wrapperType;
}

iTunes搜索数组
