php - 访问顶级嵌套 Json
问题描述
我有一个大的 JSON 文件，当它被更新等时，这个数字会随着时间的推移而逐渐变化。例如，每辆车都由一个数字表示，第一个数字从当前的 [0] 到 [159] 开始。使用下面的代码，我可以访问各种汽车的各个部件。感谢评论的帮助。
我无法以同样的方式从 JSON 中获取图像 URI。我从这个得到这个错误：Notice: Undefined index:
echo $car['Images']['ImageURI'];
任何帮助将不胜感激！
$response = json_decode($json_data, true);
foreach ($response as $index => $car) {
$car['BasicPrice'];
$car['BodyStyle']['BodyStyle'];
$car['Colour'];
$car['EngineNumber'];
$car['EngineSize'];
$car['FuelType']['FuelType'];
$car['HasServiceHistory'];
$car['IsNew'];
$car['InternetPrice'];
$car['IsReserved'];
$car['Make']['Make'];
$car['Model']['Model'];
$car['Odometer'];
$car['PhotoCount'];
$car['PreviousOwners'];
$car['RegistrationNumber'];
$car['RetailPrice'];
$car['Specification']['Doors'];
$car['StockNumber'];
$car['Transmission']['Transmission'];
}
if (!is_array($response) || empty($response)) {
return false;
}
这是第一辆车 [0] 并且遵循相同。

解决方案
JSON 几乎肯定会返回一个车辆数组，一旦它被解析，它就像您可以迭代的任何其他数组一样，您可以使用 foreach 完全忽略索引：
$response = json_decode($json_data, true);
foreach ($response as $index => $car) {
echo $car['BasicPrice'];
echo "<br>";
echo $car['BodyStyle']['BodyStyle'];
}
