解析數據從谷歌地圖API與PHP與JSON與PHP

Question

我想解析從谷歌地圖地理編碼版本3通過JSON數據。我想獲得詳細信息，如locaityName，AdministrativeAreaName和狀態碼。我可以知道如何解析這些數據嗎？謝謝

Answer 1

PHP有json_decode()，將一個JSON數據流轉換爲PHP數組或對象。

Answer 2

您可以使用json_encode和json_decode函數來解析json數據。

Answer 3

使用PHP PECL JSON庫

json_decode() 

http://php.net/manual/en/function.json-encode.php

只是一個建議，如果函數不返回任何東西，這意味着有一個語法錯誤爲JSON，它不會提高任何錯誤或日誌。

function getGoogleAddressCoordinates() 
    { 
     //using the google maps api to get the long and lat coordinates of addresss 
     //using form post variables 
     $address =trim($_POST['address']); 
     $city = trim($_POST['city']); 
     $state = trim($_POST['state']); 

     //formats the address add '+' into space 
     $address = str_replace(' ', '+' ,$address); 
     $city = str_replace(' ', '+', $city); 
     $address = preg_replace("[^A-Za-z0-9]", '+', $address); //remove non alpha numeric chars such as extra spaces. 
     $address_str = $address.',+'. $city.',+'.$state; 
     $geo_url = "http://maps.google.com/maps/api/geocode/json?address=$address_str&sensor=false"; 
     //echo $geo_url; 
     //echo file_get_contents($geo_url); 
     $json_result = json_decode(file_get_contents($geo_url)); 

     $geo_result = $json_result->results[0]; 
     $coordinates = $geo_result->geometry->location; 

     //see if the it is locating the real address or just apox location, or in most cases a bad address 
     if($geo_result->types[0] == 'street_address') 
      $coordinates->valid_address = TRUE; 
     else 
      $coordinates->valid_address = FALSE; 

     return $coordinates; 
    }
