iTunes 搜索阵列答案

【问题描述】：

我正在使用一个包装器，它使得抓取搜索词并将其转换为数组变得非常简单。

我无法解析这个数组。如何创建一个 foreach() 循环来从这个数组中获取值？

这是抓取搜索词并转换为数组的简单函数。 print_r() 只是向我展示了返回的内容。：

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，假设我搜索 Adele。这是正在返回的数组：

Array ( [0] => stdClass Object ( [wrapperType] => track [kind] => song [artistId] => 262836961 [collectionId] => 1051394208 [trackId] => 1051394215 [artistName] => Adele [ collectionName] => 25 [trackName] => 你好 [collectionCensoredName] => 25 [trackCensoredName] => 你好 [artistViewUrl] => https://itunes.apple.com/us/artist/adele/id262836961?uo=4 [collectionViewUrl] => https://itunes.apple.com/us/album/hello/id1051394208?i=1051394215&uo=4 [trackViewUrl] => https://itunes.apple.com/us/album/hello/id1051394208?i=1051394215&uo=4 [previewUrl] => http://a1912.phobos.apple.com/us/r1000/170/Music6/v4/68/34/f1/6834f1f8-8fdb-4247-492a-c0caea580082/mzaf_3920281300599106672.plus.aac.p.m4a [artworkUrl30] => http://is5.mzstatic.com/image/thumb/Music6/v4/8c/91/5d/8c915d9b-d9e4-f735-1b91-81ca1b6e6312/source/30x30bb.jpg [artworkUrl60] => http://is5.mzstatic.com/image/thumb/Music6/v4/8c/91/5d/8c915d9b-d9e4-f735-1b91-81ca1b6e6312/source/60x60bb.jpg [artworkUrl100] => http://is5.mzstatic.com/image/thumb/Music6/v4/8c/91/5d/8c915d9b-d9e4-f735-1b91-81ca1b6e6312/source/100x100bb.jpg [collectionPrice] => 10.99 [trackPrice] => 1.29 [releaseDate] => 2015-11- 20T08:00:00Z [collectionExplicitness] => notExplicit [trackExplicitness] => notExplicit [discCount] => 1 [discNumber] => 1 [trackCount] => 11 [trackNumber] => 1 [trackTimeMillis] => 295502 [国家] => 美国 [货币] => 美元 [primaryGenreName] => 流行 [radioStationUrl] => https://itunes.apple.com/station/idra.1051394215 [isStreamable] => )

这是我尝试过的，还有几个变体：

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

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

我收到错误：

Warning: Invalid argument supplied for foreach()

【解决方案1】：

假设 $results 包含您在上面给出的数组。然后是获取'wrapperType'的代码...

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

工作。不敢相信我无法弄清楚这一点。感谢您的帮助，先生。
