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);
    });

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.
