使用Laravel从数组获取JSON值 [英] Get a JSON value from an array using Laravel

问题描述

我正在尝试从JSON数组-Google从其地理编码服务返回的$response中获取纬度和经度值.

I am trying to get the latitude and longitude values from a JSON array - $response, returned from Google, from their Geocoding services.

这样返回JSON数组(随机地址):

The JSON array is returned as such (random address):

{
   "results":[
      {
         "address_components":[
            {
               "long_name":"57",
               "short_name":"57",
               "types":[
                  "street_number"
               ]
            },
            {
               "long_name":"Polo Gardens",
               "short_name":"Polo Gardens",
               "types":[
                  "route"
               ]
            },
            {
               "long_name":"Bucksburn",
               "short_name":"Bucksburn",
               "types":[
                  "sublocality_level_1",
                  "sublocality",
                  "political"
               ]
            },
            {
               "long_name":"Aberdeen",
               "short_name":"Aberdeen",
               "types":[
                  "locality",
                  "political"
               ]
            },
            {
               "long_name":"Aberdeen",
               "short_name":"Aberdeen",
               "types":[
                  "postal_town"
               ]
            },
            {
               "long_name":"Aberdeen City",
               "short_name":"Aberdeen City",
               "types":[
                  "administrative_area_level_2",
                  "political"
               ]
            },
            {
               "long_name":"United Kingdom",
               "short_name":"GB",
               "types":[
                  "country",
                  "political"
               ]
            },
            {
               "long_name":"AB21 9JU",
               "short_name":"AB21 9JU",
               "types":[
                  "postal_code"
               ]
            }
         ],
         "formatted_address":"57 Polo Gardens, Aberdeen, Aberdeen City AB21 9JU, UK",
         "geometry":{
            "location":{
               "lat":57.1912463,
               "lng":-2.1790257
            },
            "location_type":"ROOFTOP",
            "viewport":{
               "northeast":{
                  "lat":57.19259528029149,
                  "lng":-2.177676719708498
               },
               "southwest":{
                  "lat":57.18989731970849,
                  "lng":-2.180374680291502
               }
            }
         },
         "partial_match":true,
         "place_id":"ChIJLTex1jQShEgR5UJ2DNc6N9s",
         "types":[
            "street_address"
         ]
      }
   ],
   "status":"OK"
}

我尝试了以下操作:

json_decode($response->results->geometry->location->lat)

但是它返回正在尝试访问非对象的属性".

But it returns 'trying to access the property of a non-object'.

任何帮助将不胜感激.

推荐答案

var_dump(json_decode($response)->results[0]->geometry->location->lat);
