php - JSON -> PHP 数组,很难找到特定值的索引路径

我有一个 JSON 字符串,我已使用“json_decode”将其转换为关联的 PHP 数组。出于某种原因,我似乎无法弄清楚如何找到我在数组中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,我想要索引“位置”下的数组(纬度和经度键下的值)

我似乎不能比 array_name["results"] 更进一步了

是否有 var_dump 的替代方法可以对多级数组进行行分隔和缩进以便我理解它们?我宁愿使用直接路径,也不愿递归搜索整个数组以找到我要查找的内容。谢谢!

最佳答案

您是否尝试过以这种方式访问​​“位置”?:

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