实时汇率转换接口的代码分享

这两天一直在弄世界买家网的工具专栏，今天写了汇率换算，找了很多的接口，看了网上很多人的经验，xe的容易被封，google的不是实时的，而且google在内地访问不是很好，丢包率比较高。

最好看到人家用了yahoo的接口，于是借鉴过来，贴出代码来分享给大家。

代码如下：

function getExchangeRate($from_Currency,$to_Currency)
{
        $amount = urlencode($amount);
        $from_Currency = urlencode($from_Currency);
        $to_Currency = urlencode($to_Currency);
        $url = "download.finance.yahoo.com/d/quotes.html?s=".$from_Currency.$to_Currency."=X&f=sl1d1t1ba&e=.html";
        $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);
        return $data[1];
}
//调用方法
echo getExchangeRate("CNY","USD");
