Convert currency using google finance calculator in php

Earlier we used to Convert currency using Google api. But as Google has closed its iGoogle service from 1st Nov 2013, this api will no longer work. But we have an alternative to convert currency using google finance calculator.


Here is a little code snippet that can be used to convert currency from one format to another.
It takes three parameters The amount to be converted, convert from and convert to

  <?php
  function convertCurrency($amount, $from, $to){
    $url  = "https://finance.google.com/finance/converter?a=$amount&from=$from&to=$to";
    $data = file_get_contents($url);
    preg_match("/<span class=bld>(.*)<\/span>/",$data, $converted);
    $converted = preg_replace("/[^0-9.]/", "", $converted[1]);
    return round($converted, 3);
  }

  # Call function  
  echo convertCurrency(1, "USD", "INR");
  ?>

The above php function returns something like 62.285
