訪問PHP數組中的鍵值對

當轉換爲PHP數組（不是stdClass對象）時，如何才能訪問幾何位置到lat和long？我試過$ data ['results'] ['geometry'] ['location'] ['lat']和['lng']但它沒有奏效。訪問PHP數組中的鍵值對

我是越來越未定義，偏移量和不能使用字符串作爲陣列偏移等

{ 
    "results" : [ 
     { 
     "address_components" : [ 
      { 
       "long_name" : "1600", 
       "short_name" : "1600", 
       "types" : [ "street_number" ] 
      }, 
      { 
       "long_name" : "Amphitheatre Parkway", 
       "short_name" : "Amphitheatre Pkwy", 
       "types" : [ "route" ] 
      }, 
      { 
       "long_name" : "Mountain View", 
       "short_name" : "Mountain View", 
       "types" : [ "locality", "political" ]

      {

       "long_name" : "California",

$data['results']是索引數組。你只需要修復您是如何訪問它：

$data['results'][0]['geometry']['location']['lat']

呵呵。我也是，nem ;-) – 2014-09-26 20:56:21

沒問題，樂於幫忙！ @恩對不起！：P – 2014-09-26 21:01:52

你的道：

$data['results']['geometry']['location']['lat'] // same for ['lng']

你忘了把指數

$data['results'][0]['geometry']['location']['lat'] // same for ['lng']

你似乎已經錯過了$data['results']是有一個元素的數組，因此您需要使用[0]來引用該元素。

嘗試：$data['results'][0]['geometry']['location']['lat']
