Php 从没有数组的json数据中提取信息

这是我的json数据文件：

我尝试使用此代码显示来自kson代码的信息，但我无法获得作品

我需要从json文件中提取数据，并显示来自英国的信息，例如“en”和“extract price”，但我认为这一切都没问题，但肯定有一些问题是不好的，因为我无法得到问题

我尝试了许多组合，但没有得到任何结果，如果你能告诉我哪里错了，那就完美了，谢谢

试试这个

foreach ($rr->apollo->data as $key => $value) {
        if(isset($value->price)){
            echo $value->price;
            echo "</br>";
        }
     }

foreach（$rr->apollo->data as$key=>$value）{
如果（设置（$value->price））{
echo$value->price；
回声“
”；
}
}

试试这个

foreach ($rr->apollo->data as $key => $value) {
        if(isset($value->price)){
            echo $value->price;
            echo "</br>";
        }
     }

foreach（$rr->apollo->data as$key=>$value）{
如果（设置（$value->price））{
echo$value->price；
回声“
”；
}
}

阿波罗的可能副本是一个对象，而不是数组。您将无法按您认为的方式使用foreach。Apollo有1个数据（对象，不是数组），1个ProductItem（对象，不是数组）。你能给我一些代码吗？我可以用它来提取这些信息，并学习如何使用这个json，thanks@AlfredoAguinFigueiro-你能把你想要打印的样本格式放进去吗。这将有助于理解所需的输出是什么。因此将帮助你编码。我想提取英国的价格，你可以看到显示国家，在价格下，我想显示英国或每个国家的价格，举个例子，这对我来说很完美，感谢阿波罗的可能副本是一个对象，而不是数组。您将无法按您认为的方式使用foreach。Apollo有1个数据（对象，不是数组），1个ProductItem（对象，不是数组）。你能给我一些代码吗？我可以用它来提取这些信息，并学习如何使用这个json，thanks@AlfredoAguinFigueiro-你能把你想要打印的样本格式放进去吗。这将有助于理解所需的输出是什么。因此，将帮助你编码。我想提取英国的价格，你可以看到显示国家和价格下，我想显示英国或每个国家的价格，这是我的完美的例子谢谢
