因此，我正在使用API车辆，我遇到了障碍，希望从那些对此有更多经验的人那里获得一些意见。。。首先，我将展示从API调用返回的数据示例。

因此，如果我把这些数据存储在一个名为$data的变量中，例如，我可以做这样的事情，它可以工作：
foreach ($data['options'] as $options) {
echo $options['category'];
}
这会还给我"安全"answers"包裹"。
然而，如果我想得到汽车的品牌，我会做这样的事情：
foreach ($data['make'] as $make) {
echo $make['name'];
}
它只是给我返回一个值：Cc（make name中的大写C，make niceName中的小写C）。它为什么要这么做？我做错了什么？
谢谢！
只有一个'make'，所以我认为您只需要这个（无循环）：
echo $data['make']['name'];
$data['make']的每个元素都是string（可能是integer），但不是像$data['options']的每个元素一样是array。所以，在$data['make']的情况下，不能使用[]表示法。
只是：
foreach ($data['make'] as $make) {
echo $make;
}
会做你需要的事。
