php – PayPal for Indian Rupees(INR)任何解决方案

我正在开发网上购物网站,在购物网站上所有产品的价格均为印度卢比(INR).我打算将我的购物车集成到PayPal支付网关.
我知道PayPal不支持INR.所以我必须将INR兑换成美元.
是否有任何API服务可以自动将INR转换为USD？如果是,请详细说明……

您可以使用Google计算器API.

这是一个PHP示例：

function currency_converter($from_Currency,$to_Currency,$amount) {
  $url = "http://www.google.com/ig/calculator?hl=en&q=$amount$from_Currency=?$to_Currency";      

  $amount = urlencode($amount);
  $from_Currency = urlencode($from_Currency);
  $to_Currency = urlencode($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'];

  return round($var,2);
}
