我如何从JSON获取值

Question

这是我要求获取反向地理编码的请求

https://maps.googleapis.com/maps/api/geocode/json?latlng=11.2100,76.9500&key=AIzaSyC2pESdfUbnL2i1eHrJY4v6cWLI9EJePCo

这是我的JSON结果

我如何在formatted_address获取值

Mettupalayam Road, Bilichi, Tamil Nadu 641104, India价值Mettupalayam Road, Bilichi, Tamil Nadu 641104, India

"formatted_address" : "Mettupalayam Road, Bilichi, Tamil Nadu 641104, India",

Answer 1

使用php的json_decode

$jsondata = json_decode ( $result, true);

之后，您可以使用

echo $jsondata['results']['formatted_address'];

PS：在json_decode中，第一个是要转换为json的字符串，第二个是返回对象（false）还是仅返回关联数组（true）的选项

Answer 2

尝试这个..

  $json = json_decode ( $result, true);

    echo $json['results'][0]['formatted_address'];

结果：印度泰米尔纳德邦Bilichi的Mettupalayam Road 641104

Answer 3

你可以这样尝试：

$json = 'your json here';

$ data = json_decode（$ json）;

echo $ data-> results [0]-> formatted_address;

结果：印度泰米尔纳德邦Bilichi的Mettupalayam Road 641104

您可以将索引0更改为1,2,3 ...
