Reverse Geocoding With Google Map API And PHP To Get Nearest Location Using Lat,Long coordinates

Question

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

Answer 1

You need to use the getLocations method on the GClientGeocoder object in the Google Maps API

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);
    });

You can find a working example of this here. This example is also doing walking directions between two points, but if you have a look at the getLocations call in the dragend listener it does the geocode each time the end point is moved.

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:

// 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 service explicitly states that geocoding data without putting the results on a Google Map is prohibited.

Answer 2

The 'address' return is actually: $jsondata ['Placemark'][0]['address'];
