Google 财经货币转换器

Question

我正在研究 google 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");

google 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..只是把我的答案贴出来给以后需要的人。

<?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");

Answer 2

当您从 google 转换器 "Could not convert" 收到消息时 - 这意味着转换
1 CURRENCY_A --> CURRENCY_B 结果太小数量。在这种情况下你需要进行反向转换CURRENCY_A_AMOUNT / (1 CURRENCY_B --> CURRENCY_A)

最后，我通过更新的 google URL 货币转换器找到了解决方案。

finance.google.com 已停产，试试这些：

// google API - Load time: 558 ms
function google_money_convert($from, $to, $amount)
{
    $url = "https://www.google.com/search?q=".$from.$to;
    $request = curl_init();
    $timeOut = 0;
    curl_setopt($request, CURLOPT_URL, $url);
    curl_setopt($request, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($request, CURLOPT_USERAGENT, "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/68.0.3440.106 Safari/537.36");

    curl_close($request);

    preg_match('~<span [^>]* id="knowledge-currency__tgt-amount"[^>]*>(.*?)</span>~si', $response, $finalData);
    $finalData=str_replace(',', '.', $finalData);
    return (float)$finalData[1]*$amount;
}


// free.currencyconverter API - Load time: 95ms
function money_convert($from, $to, $amount)

    $url = "http://free.currencyconverterapi.com/api/v5/convert?q=$query&compact=ultra";
    $request = curl_init();
    $timeOut = 0;

    curl_close($request);
    $response = json_decode($response, true);
    $responseOld=$response;
    // print_r($response);
    return $response[$query]*$amount;
}
