If you need to do this on the backend you can use the following URL structure:

https://maps.googleapis.com/maps/api/geocode/json?address=[STREET_ADDRESS]&key=[YOUR_API_KEY]

Sample PHP code using curl:

$curl = curl_init();

curl_setopt($curl, CURLOPT_URL, 'https://maps.googleapis.com/maps/api/geocode/json?address=' . rawurlencode($address) . '&key=' . $api_key);

curl_setopt ($curl, CURLOPT_RETURNTRANSFER, 1);

$json = curl_exec($curl);

curl_close ($curl);

$obj = json_decode($json);

See additional documentation for more details and expected json response.

The docs provide sample output and will assist you in getting your own API key in order to be able to make requests to the Google Maps Geocoding API.

There is a pretty good example on https   developers google com maps documentation javascript examples geocoding-simple  To shorten it up a little   geocoder   new google maps Geocoder     function codeAddress            In this case it gets the address from an element on the page  but obviously you  could just pass it to the method instead     var address   document getElementById   address    value       geocoder geocode     address    address    function  results  status             if  status    google maps GeocoderStatus OK                    In this case it creates a marker  but you can get the lat and lng from the location LatLng             map setCenter  results 0  geometry location                var marker   new google maps Marker                    map       map                  position  results 0  geometry location                            else               alert   Geocode was not successful for the following reason      status
