利用yahoo汇率接口实现实时汇率转换示例 汇率转换器

代码如下：

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");
