JSON-> PHP数组,很难找到特定值的索引路径

我有一个JSON字符串,已使用“ json_decode”将其转换为关联的PHP数组.由于某种原因,我似乎无法弄清楚如何找到数组中要查找的值的索引路径.

这是JSON字符串：

    {
  "status": "OK",
  "results": [ {
    "types": [ "street_address" ],
    "formatted_address": "175 Hemenway St, Boston, MA 02115, USA",
    "address_components": [ {
      "long_name": "175",
      "short_name": "175",
      "types": [ "street_number" ]
    }, {
      "long_name": "Hemenway St",
      "short_name": "Hemenway St",
      "types": [ "route" ]
    }, {
      "long_name": "Boston",
      "short_name": "Boston",
      "types": [ "locality", "political" ]
    }, {
      "long_name": "Boston",
      "short_name": "Boston",
      "types": [ "administrative_area_level_3", "political" ]
    }, {
      "long_name": "Suffolk",
      "short_name": "Suffolk",
      "types": [ "administrative_area_level_2", "political" ]
    }, {
      "long_name": "Massachusetts",
      "short_name": "MA",
      "types": [ "administrative_area_level_1", "political" ]
    }, {
      "long_name": "United States",
      "short_name": "US",
      "types": [ "country", "political" ]
    }, {
      "long_name": "02115",
      "short_name": "02115",
      "types": [ "postal_code" ]
    } ],
    "geometry": {
      "location": {
        "lat": 42.3411740,
        "lng": -71.0912860
      },
      "location_type": "ROOFTOP",
      "viewport": {
        "southwest": {
          "lat": 42.3380264,
          "lng": -71.0944336
        },
        "northeast": {
          "lat": 42.3443216,
          "lng": -71.0881384
        }
      }
    }
  } ]
}

这是PHP中关联数组的var_dump输出

array(2) { ["status"]=> string(2) "OK" ["results"]=> array(1) { [0]=> array(4) { ["types"]=> array(1) { [0]=> string(14) "street_address" } ["formatted_address"]=> string(38) "175 Hemenway St, Boston, MA 02115, USA" ["address_components"]=> array(8) { [0]=> array(3) { ["long_name"]=> string(3) "175" ["short_name"]=> string(3) "175" ["types"]=> array(1) { [0]=> string(13) "street_number" } } [1]=> array(3) { ["long_name"]=> string(11) "Hemenway St" ["short_name"]=> string(11) "Hemenway St" ["types"]=> array(1) { [0]=> string(5) "route" } } [2]=> array(3) { ["long_name"]=> string(6) "Boston" ["short_name"]=> string(6) "Boston" ["types"]=> array(2) { [0]=> string(8) "locality" [1]=> string(9) "political" } } [3]=> array(3) { ["long_name"]=> string(6) "Boston" ["short_name"]=> string(6) "Boston" ["types"]=> array(2) { [0]=> string(27) "administrative_area_level_3" [1]=> string(9) "political" } } [4]=> array(3) { ["long_name"]=> string(7) "Suffolk" ["short_name"]=> string(7) "Suffolk" ["types"]=> array(2) { [0]=> string(27) "administrative_area_level_2" [1]=> string(9) "political" } } [5]=> array(3) { ["long_name"]=> string(13) "Massachusetts" ["short_name"]=> string(2) "MA" ["types"]=> array(2) { [0]=> string(27) "administrative_area_level_1" [1]=> string(9) "political" } } [6]=> array(3) { ["long_name"]=> string(13) "United States" ["short_name"]=> string(2) "US" ["types"]=> array(2) { [0]=> string(7) "country" [1]=> string(9) "political" } } [7]=> array(3) { ["long_name"]=> string(5) "02115" ["short_name"]=> string(5) "02115" ["types"]=> array(1) { [0]=> string(11) "postal_code" } } } ["geometry"]=> array(3) { ["location"]=> array(2) { ["lat"]=> float(42.341174) ["lng"]=> float(-71.091286) } ["location_type"]=> string(7) "ROOFTOP" ["viewport"]=> array(2) { ["southwest"]=> array(2) { ["lat"]=> float(42.3380264) ["lng"]=> float(-71.0944336) } ["northeast"]=> array(2) { ["lat"]=> float(42.3443216) ["lng"]=> float(-71.0881384) } } } } } }

理想情况下,我希望在索引“位置”下的数组(在lat& lng键下的值)

我似乎无法比array_name [“ results”]更进一步

也许有替代var_dump的方法,它将行分隔并缩进多级数组,以便我可以理解它们？我宁愿使用直接路径,也不愿递归搜索整个数组以查找所需的内容.谢谢！

解决方法:

您是否尝试过通过这种方式访问​​“位置”？：

$location = $array_name['results'][0]['geometry']['location'];
$lat = $location['lat'];
$lng = $location['lng'];
