위도와 경도에서 영국 우편 번호를받는 방법은 무엇입니까?

Question

위도와 경도를 알고있는 경우 영국 위치의 우편 번호를 찾는 방법이 필요합니다. 예를 들어

:

주소 : 올드 사슴 공원, 리치몬드, 그레이터 런던 TW9 2SL, 영국

나는 방식을 필요로이 정보를 사용하여 위도 = 51.4691, 경도 = -0.2963

프로그래밍 방식으로 해당 위치의 우편 번호를 검색합니다.

Answer 1

해결하려는 문제를 역 지오 코딩이라고합니다. 예제를 제공하는 Google maps documentation을 살펴보십시오. 그것은 latlng 매개 변수가있는 URL로 귀결됩니다. XML 또는 JSON을 선택할 수 있습니다. 많은 결과가있을 수 있으므로 반환 된 구조를 반복하고 가장 적절한 것을 선택해야합니다. CURL + JSON을 사용하여

http://maps.googleapis.com/maps/api/geocode/json?latlng=51.4691,-0.2963&sensor=false

사용 예제.

function getPostcode($lat, $lng) { 
    $returnValue = NULL; 
    $ch = curl_init(); 
    $url = "http://maps.googleapis.com/maps/api/geocode/json?latlng=${lat},${lng}&sensor=false"; 
    curl_setopt($ch, CURLOPT_URL, $url); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); 
    $result = curl_exec($ch); 
    $json = json_decode($result, TRUE); 

    if (isset($json['results'])) { 
    foreach ($json['results'] as $result) { 
     foreach ($result['address_components'] as $address_component) { 
      $types = $address_component['types']; 
      if (in_array('postal_code', $types) && sizeof($types) == 1) { 
      $returnValue = $address_component['short_name']; 
      } 
    } 
    } 
    } 
    return $returnValue; 
} 

echo getPostcode(51.4691, -0.2963); 

Answer 2

그것은 구글지도의 일부가 아닌 -하지만 영국의 우편 번호 API는 여기있다 : 그것은 당신이 위도와 위치의 경도 등 그에게 요청을 보낼 수 있습니다

http://www.uk-postcodes.com/api.php

은 해당 위치에 대한 영국 우편 번호를 반환합니다.

작동하는지는 잘 모르겠지만 시도해 볼 가치가 있습니다!

Answer 3

나는이 코드를 사용하여 우편 번호를 가져 오는 방법이 코드를 이미 사용하고 있습니다. 및 from_address에서 to_address까지의 예상 소요 시간.
