service.search(request, callback);
function callback(results, status) {
if (status == google.maps.places.PlacesServiceStatus.OK) {
for (var i = 0; i < results.length; i++) {
var lat = results[i].geometry.location.lat();
var geocoder = new google.maps.Geocoder();
var lng = results[i].geometry.location.lng();
var latlng = new google.maps.LatLng(lat, lng);
geocoder.geocode({
'latLng': latlng
}, function (result, status1) {
if (status == google.maps.GeocoderStatus.OK) {
if (result[1]) {
console.log(result[1]);
}
} else {
alert("Geocoder failed due to: " + status1);
}
});
}
}
}
I want near cities not like the stores etc. I have to find the suburbs in the Australia what are near to the suburb which i given

I've written a code snippet that allows you to retrieve all nearby cities by combining the Google Maps Geocoding API and GeoNames.org API (besides a file_get_contents your could also do a cURL request).
/*
* Get cities based on city name and radius in KM
*/
// get geocode object as array from The Google Maps Geocoding API
$geocodeObject = json_decode(file_get_contents('https://maps.googleapis.com/maps/api/geocode/json?address={CITY NAME},{COUNTRY CODE}'), true);
// get latitude and longitude from geocode object
$latitude = $geocodeObject['results'][0]['geometry']['location']['lat'];
$longitude = $geocodeObject['results'][0]['geometry']['location']['lng'];
// set request options
$responseStyle = 'short'; // the length of the response
$citySize = 'cities15000'; // the minimal number of citizens a city must have
$radius = 30; // the radius in KM
$maxRows = 30; // the maximum number of rows to retrieve
$username = '{YOUR USERNAME}'; // the username of your GeoNames account
// get nearby cities based on range as array from The GeoNames API
$nearbyCities = json_decode(file_get_contents('http://api.geonames.org/findNearbyPlaceNameJSON?lat='.$latitude.'&lng='.$longitude.'&style='.$responseStyle.'&cities='.$citySize.'&radius='.$radius.'&maxRows='.$maxRows.'&username='.$username, true));
// foreach nearby city get city details
foreach($nearbyCities->geonames as $cityDetails)
{
// do something per nearby city
}
be carefull with your requests amount because the API's are limited
