访问顶级嵌套Json

时间：2019-08-22 14:08:44

标签： php arrays json

我有一个大的JSON文件，当更新等时，该数字将随着时间的推移而逐渐变化。例如，每辆车用一个数字表示，第一个数字从[0]到[159]开始。使用下面的代码，我可以从各种汽车中访问各个零件。感谢评论的帮助。

我无法以相同的方式从JSON获取图像URI。我收到以下错误消息：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;
            }

这是第一辆汽车[0]，并且紧随其后。

JSON几乎肯定会返回载具数组，一旦解析后，就可以像其他任何可以迭代的数组一样，并且可以通过使用foreach完全忽略索引：

* {
  box-sizing: border-box; /** that's it ! **/
}

aside,
article,
section,
header,
footer,
nav {
  display: block;
}

div,
p {
  margin: 0;
  padding: 0;
}

html {
  background: #ccc;
}

.outer {
  /* TOTAL WIDTH: 700px */
  width: 600px;
  margin: 0 auto;
  background: #9CF;
  padding: 50px;
}

.box {
  background: #B7D19C;
  /* TOTAL WIDTH: 700px */
  width: 500px;
  padding: 98px;
  border: 2px black solid;
}

p {
  background: #FF9;
  height: 100%;
  /* here */
}

最简单的示例： 函数array_map将自定义函数应用于$ response中的每个项目。

array_map(function ($car) {
   echo car['BasicPrice'];
   echo "<br>";
   echo $car['BodyStyle']['BodyStyle'];
   echo "<br>";
}, $response);
