php - 谷歌财经货币转换器

Question

我正在使用谷歌货币转换器，它适用于所有货币，但未显示 ZAR - BTC 转换的结果。

Google 货币转换器代码:

<?php
function convertCurrency($amount, $from, $to){
    $data = file_get_contents("https://finance.google.com/finance/converter?a=$amount&from=$from&to=$to");
    preg_match("/<span class=bld>(.*)<\/span>/",$data, $converted);
    $converted = preg_replace("/[^0-9.]/", "", $converted[1]);
    return number_format(round($converted, 3),2);
}
echo convertCurrency("1000000", "ZAR", "BTC");

谷歌的预期结果应该是 8.26 但它显示消息 Could not convert

Answer 1

我找到了一种方法来做到这一点.. 只是将我的答案粘贴给将来需要的人。

<?php
function convertCurrency($amount, $from, $to){
    $data = file_get_contents("https://finance.google.com/finance/converter?a=$amount&from=$from&to=$to");
    preg_match("/<span class=bld>(.*)<\/span>/",$data, $converted);
    $converted = preg_replace("/[^0-9.]/", "", $converted[1]);
    return number_format(round($converted, 3),2);
}
 convertCurrency("1", "BTC", "ZAR");



function ZARtoBTC($amount){
      $BTC = convertCurrency("1", "BTC", "ZAR");
       $f_amount = number_format($amount, 3);

        $val = $f_amount / $BTC ;

       return  number_format($val, 2);
}
echo ZARtoBTC("100000");
