利用yahoo匯率接口實現實時匯率轉換示例

 這篇文章主要介紹了利用yahoo匯率接口實現實時匯率轉換示例，大家參考使用吧

代碼如下：   代碼如下: 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]; } //調用方法 echo getExchangeRate("CNY","USD");
