There are many free geolocation services out there, One notably maxmind's services, You can filter the database yourself or use said software to get the lookup.

Use the Google Maps API.  I recently posted a blog post on exactly this at http://www.murraypicton.com/2010/12/free-uk-postcode-lookup-using-the-google-maps-api/

 

Hope it helps!

    // First, we need to take their postcode and get the lat/lng pair:

    $postcode = $_REQUEST['postcode'];

    // Sanitize their postcode:

    $search_code = urlencode($postcode);

    $url = 'http://maps.googleapis.com/maps/api/geocode/json?address=' . $search_code . '&sensor=false';

    $json = json_decode(file_get_contents($url));

    $lat = $json->results[0]->geometry->location->lat;

    $lng = $json->results[0]->geometry->location->lng;

    // Now build the lookup:

    $address_url = 'http://maps.googleapis.com/maps/api/geocode/json?latlng=' . $lat . ',' . $lng . '&sensor=false';

    $address_json = json_decode(file_get_contents($address_url));

    $address_data = $address_json->results[0]->address_components;

    $street = str_replace('Dr', 'Drive', $address_data[1]->long_name);

    $town = $address_data[2]->long_name;

    $county = $address_data[3]->long_name;

	$city = $address_data[4]->long_name;

	$country = $address_data[5]->long_name;

	$array = array('street' => $street, 'town' => $town, 'city' => $city, 'country' => $country);

    //echo json_encode($array);

	echo $array = implode(", ",$array);
