Google Currency Converter has changed its URL but not getting same result

I have the following code (below) and was using the iGoogle version.

   $url = 'http://www.google.com/ig/calculator?hl=en&q=' . $amount . $from_Currency . '=?' . $to_Currency;

    $ch = curl_init();
    $timeout = 0;

    curl_setopt ($ch, CURLOPT_URL, $url);
    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch,  CURLOPT_USERAGENT , "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1)");
    curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
    $rawdata = curl_exec($ch);
    curl_close($ch);

    $data = explode('"', $rawdata);
    $data = explode(' ', $data[3]);
    $var = $data[0];

BUT having looked they are using a different URL:

  'http://www.google.com/finance/converter?hl=en&a=' . $amount . '&from=' . $from_Currency . '&to=USD';

But simply changing the url does not return the required result that i was used to.

Now all i would get is

 http://www.w3.org/TR/html4/strict.dtd

SO has anyone worked on this latest currency converter URL or have any ideas. Or a replacement using PHP

Solution

Thanks to some more in depth looking and rewording of issue found this post. So in a way its a duplicate. but here is the question:

Need API for currency converting

I used @hobailey answer for a temporary fix until i can update it to another version or google decide to do a proper api.

  $amount = urlencode($amount);
  $from_Currency = urlencode($from_Currency);
  $to_Currency = urlencode($to_Currency);
  $get = file_get_contents("https://www.google.com/finance/converter?a=$amount&from=$from_Currency&to=$to_Currency");
  $get = explode("<span class=bld>",$get);
  $get = explode("</span>",$get[1]);  
  $converted_amount = preg_replace("/[^0-9\.]/", null, $get[0]);
