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");
