PHP – Google Currency Converter

May 13th, 2012 by Laeeq | 1 comment

As you may know, Google has a calculator feature built in their search engine, which can be used to convert measures, currencies, get stock quotes, weather data and many other features

Here is a simple php function that converts a currency into another using the Google calculator API .
This example uses cURL , so you have to have it enabled for this code to work .

Example Code :
view plaincopy to clipboardprint?
  1. <?php
  2. function currency($from_Currency,$to_Currency,$amount) {
  3. $amount = urlencode($amount);
  4. $from_Currency = urlencode($from_Currency);
  5. $to_Currency = urlencode($to_Currency);
  6. $url = “http://www.google.com/ig/calculator?hl=en&q=$amount$from_Currency=?$to_Currency”;
  7. $ch = curl_init();
  8. $timeout = 0;
  9. curl_setopt ($ch, CURLOPT_URL, $url);
  10. curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
  11. curl_setopt($ch,  CURLOPT_USERAGENT , “Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1)”);
  12. curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
  13. $rawdata = curl_exec($ch);
  14. curl_close($ch);
  15. $data = explode(‘”’, $rawdata);
  16. $data = explode(‘ ‘, $data[‘3′]);
  17. $var = $data[‘0′];
  18. return round($var,3);
  19. }
  21. ?>

Hope it will be useful for you!
