php - 使用 Laravel 从数组中获取 JSON 值

Question

我正在尝试从 JSON 数组获取纬度和经度值 - $response，从 Google 的地理编码服务返回。

JSON 数组原样返回(随机地址):

{
   "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"
}

我尝试了以下方法:

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

但它返回“试图访问非对象的属性”。

如有任何帮助，我们将不胜感激。

Answer 1

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