我一直无法在API返回的数组中检索值，通常是因为它们非常复杂。无论如何，这个让我难过。
我不会在这里发布整个数组..但下面是它的要点。
只是为了让你知道，我已经尝试嵌套了几个foreach循环，但我收到了几个错误，我无法想象没有更简单的方法来做它。
提前感谢您的帮助。

我正在尝试检索ItemAttributes-＆gt;标题部分和DetailPageURL。期待听到建议。
感谢。

尝试这一点我认为它会做你想要的，虽然我没有测试过它
$amazon_array = $your_big_ass_amazon_array; // replace this with the array you show in your post
$items = $your_big_ass_amazon_array['Items'];
foreach($items as $item) {
$ItemAttributes = getSubArrayByIndex($item, 'ItemAttributes');
$tittles[] = $ItemAttributes['title'];
}
print_r($titles);
function getSubArrayByIndex($array, $index) {
if (!is_array($array)) return null;
if (isset($array[$index])) return $array[$index];
foreach ($array as $item) {
$return = getSubArrayByIndex($item, $index);
if (!is_null($return)) {
return $return;
}
}
return null;
}
