Question

我正在使用Amazon API来提取产品信息。我用它来提取信息：

$response = $amazonEcs->responseGroup('OfferFull')->lookup('B00IXO8I0O');
var_dump($response);

它输出（警告 - 长输出，你可以滚动到底部）：

我无法弄清楚如何获得＆＃34; FormattedPrice。＆＃34; （或任何相关项目）

如何开始从中取出数据而不是var_dump（）。

您可以像普通实例变量一样访问StdClass属性：$obj->param。例如，在这种情况下，我们可以访问＆＃39; FormattedPrice＆＃39;像这样：

echo $response->Items->Item->OfferSummary->LowestNewPrice->FormattedPrice; // $299.99

如何从stdClass中获取JSON项
