Geocoder – find your latitude and longitude

Here is a quick way to find your latitude and longitude. It is a PHP script using the Google geocoding service. The Google Store Locator demo on this site utilizes the latitude and longitude from such a request to locate nearby Cyberstarweb locations. With this script as a start, you could build an entire site like geocoder.us

Here is the PHP source code of the geocoder.php

<?php

   if ($_POST['address'] != "") {
   		doGeo(urlencode($_POST['address']));
   		}

   doGeo($marker) {
   // Your Google Maps API key
   $key = "Your key here";
   // Desired address
   $address = "http://maps.google.com/maps/geo?q=$marker&output=xml&key=$key";
   // Retrieve the URL contents
   $page = file_get_contents($address);
   // Parse the returned XML file
   $xml = new SimpleXMLElement($page);
// Retrieve the desired XML node
//   echo $xml->Response->Placemark->Point->coordinates;
   // Parse the coordinate string
   list($longitude, $latitude, $altitude) = explode($xml->Response->Placemark->Point->coordinates);

   // Output the coordinates
	echo($marker)." Longitude: $longitude, Latitude: $latitude";
}
?>
