    $yql_query = 'select * from yahoo.finance.xchange where pair in ("'.$ffrom.$tto.'")';
    $yql_query_full_url = $yql_url . "?q=" . urlencode($yql_query);
    $yql_query_full_url .= "&format=json&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys";
    $yql_curl = curl_init($yql_query_full_url);
