Reverse Geocoding With Google Map API And PHP To Get Nearest Location Using Lat,Long coordinates
提问by Murugesh
I need a function to get an nearest address or city from coordinates(lat,long) using google map api reverse geocoding and php... Please give some sample code

You need to use the getLocationsmethod on the GClientGeocoderobject in the Google Maps API
您需要在Google Maps API 中的GClientGeocoder对象上使用getLocations方法
var point = new GLatLng (43,-75);
var geocoder = new GClientGeocoder();
geocoder.getLocations (point, function(result) {
// access the address from the placemarks object
alert (result.address);
});
EDIT: Ok. You are doing this stuff server side. This means you need to use the HTTP Geocoding service. To do this you will need to make an HTTP request using the URL format described in the linked article. You can parse the HTTP response and pull out the address:
编辑：好的。你在服务器端做这个东西。这意味着您需要使用HTTP 地理编码服务。为此，您需要使用链接文章中描述的 URL 格式发出 HTTP 请求。您可以解析 HTTP 响应并拉出地址：
// set your API key here
$api_key = "";
// format this string with the appropriate latitude longitude
$url = 'http://maps.google.com/maps/geo?q=40.714224,-73.961452&output=json&sensor=true_or_false&key=' . $api_key;
// make the HTTP request
$data = @file_get_contents($url);
// parse the json response
$jsondata = json_decode($data,true);
// if we get a placemark array and the status was good, get the addres
if(is_array($jsondata )&& $jsondata ['Status']['code']==200)
{
$addr = $jsondata ['Placemark'][0]['address'];
}
N.B.The Google Maps terms of serviceexplicitly states that geocoding data without putting the results on a Google Map is prohibited.
NB的服务的谷歌地图条款明确规定，没有把结果在谷歌地图的地理编码数据是禁止的。
