≡ 通过GOOGLE(谷歌) API获取实时货币汇率(人民币和美金)的PHP代码

调用方法:

echo $this->currency("USD", "CNY", 1);die;

当前（2016年6月11日汇率是6.56)

函数:

function currency($from_Currency, $to_Currency, $amount) {

    $url = "https://www.google.com/finance/converter?a=" . $amount . "&from=" . $from_Currency . "&to=" . $to_Currency;

    $ch = curl_init();

    $timeout = 0;

    curl_setopt ($ch, CURLOPT_URL, $url);

    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);

    curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);

    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

    $rawdata = curl_exec($ch);

    curl_close($ch);

    $matches = array();

    preg_match_all("|<span class=bld>(.*)</span>|U", $rawdata, $matches);

    $result = explode(" ", $matches[1][0]);

    return round($result[0], 2);
