A helper function for UK Postcodes, adapted from the original function I wrote for the Ernest Marples service
<?php
function ernest_marples($postcode) {
$postcode = str_replace(" ", "", $postcode);
$url = "http://www.uk-postcodes.com/postcode/". urlencode($postcode) .".csv"; // Build the URL
$file = file_get_contents($url);
if (strpos($file, "html") === FALSE) { // Some error checking - if the file contains html, then we've been redirected to the homepage and something has gone wrong
