從經緯度得到國家，地區和城市名稱（PHP）

Question

我想從Google地圖API獲取經緯度的國家，pincode，州和城市名稱 - 使用PHP。但有時它的工作是正確的，但有時會得到錯誤的信息，並且很多時候它會返回空值，因爲結果是動態的而不是固定的。

所以任何人都建議我如何使這個充滿活力和檢查裏面是全國城市PIN碼和狀態在任何從結果數組索引的可用....

下面

是我的代碼...

$fromlat = $this->request->data['Order']['from_lat']; 
      $fromlong = $this->request->data['Order']['from_long']; 

      $geocode = file_get_contents('http://maps.googleapis.com/maps/api/geocode/json?latlng='.$fromlat.','.$fromlong.'&sensor=false'); 
      $json = json_decode($geocode); 

      //print_r($geocode); 
      $country = $json->{'results'}[1]->{'address_components'}[3]->{'long_name'}; 
      $state = $json->{'results'}[1]->{'address_components'}[2]->{'long_name'}; 
      $city = $json->{'results'}[1]->{'address_components'}[1]->{'long_name'};    
      $locality = $json->{'results'}[1]->{'address_components'}[0]->{'long_name'};   
      $pincode = $json->{'results'}[1]->{'address_components'}[4]->{'long_name'};     
      echo $locality."</br>".$country."</br>".$state."</br>".$city."</br>".$pincode; 

我需要在結果forloop中檢查地址組件中的類型，如果可用則顯示結果。下面

types = country = country name; 
      types = administrative_area_level_1 = state name ; 
      types = administrative_area_level_2 = city name ; 
      types = postal_code = pincode ; 

是我的結果數組...

我有一個被稱爲工作有些類似的代碼。基本上它可以返回一個結果數組，如果有多個可能的結果，或者只有一個對象，如果只有一個結果被發現。我的用例略有不同，但希望它有幫助。試試這個：

$ch = curl_init(); 
    $geoCodeUrl = 'https://maps.googleapis.com/maps/api/geocode/json?address=' . $zip . ',+United+States&key=' . $googleApiKey; 
    curl_setopt($ch,CURLOPT_URL, $geoCodeUrl); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
    curl_setopt($ch, CURLOPT_TIMEOUT, 5); 
    $result = curl_exec($ch); 
    curl_close($ch); 

    $GeoCode = json_decode($result); 
    $GeoLocator = new \stdClass(); 

    if(isset($GeoCode->results[0])){ 
     $GeoLocator->lat = $GeoCode->results[0]->geometry->location->lat; 
     $GeoLocator->lon = $GeoCode->results[0]->geometry->location->lng; 
     foreach($GeoCode->results[0]->address_components as $comp){ 
      if(in_array('locality',$comp->types)){ 
       $GeoLocator->city = trim($comp->short_name); 
      } 
      else if(in_array('administrative_area_level_1',$comp->types)){ 
       $GeoLocator->state = strtoupper(trim(preg_replace('/\d/', '', $comp->short_name))); 
      } 
     } 

    } 
    else if(isset($GeoCode->results) && isset($GeoCode->results->geometry)){ 
     $GeoLocator->lat = $GeoCode->results->geometry->location->lat; 
     $GeoLocator->lon = $GeoCode->results->geometry->location->lng; 
     foreach($GeoCode->results->address_components as $comp){ 
      if(in_array('locality',$comp->types)){ 
       $GeoLocator->city = trim($comp->short_name); 
      } 
      else if(in_array('administrative_area_level_1',$comp->types)){ 
       $GeoLocator->state = strtoupper(trim(preg_replace('/\d/', '', $comp->short_name))); 
      } 
     } 
    }
