Php 在opencart中将印度卢比转换为美元

如何在opencart中将印度卢比转换为美元。我试过下面的代码

    $json_from = number_format($item_total, 2, '.', '');
    $url = "http://rate-exchange.appspot.com/currency?from='.$json_from.'&to=USD";
    $jsons = @file_get_contents($url);
    $json_data = json_decode($jsons, true);
    $to_cur = $json_data['results'][0];


    $data['PAYMENTREQUEST_0_ITEMAMT'] = $to_curr;
    $data['PAYMENTREQUEST_0_AMT'] = $to_curr;

你对api的url调用不正确，你需要像这样调用

    $json_from = number_format($item_total, 2, '.', '');
    $url = "http://rate-exchange.appspot.com/currency?from='.$json_from.'&to=USD";
    $jsons = @file_get_contents($url);
    $json_data = json_decode($jsons, true);
    $to_cur = $json_data['results'][0];


    $data['PAYMENTREQUEST_0_ITEMAMT'] = $to_curr;
    $data['PAYMENTREQUEST_0_AMT'] = $to_curr;

$url = "http://rate-exchange.appspot.com/currency?from=INR&to=USD";

从那里，您将获得将印度卢比转换为美元的转换率，就像现在给出的

0.0168728

和您的金额的倍数一样，以获得预期结果

    $json_from = number_format($item_total, 2, '.', '');
    $url = "http://rate-exchange.appspot.com/currency?from='.$json_from.'&to=USD";
    $jsons = @file_get_contents($url);
    $json_data = json_decode($jsons, true);
    $to_cur = $json_data['results'][0];


    $data['PAYMENTREQUEST_0_ITEMAMT'] = $to_curr;
    $data['PAYMENTREQUEST_0_AMT'] = $to_curr;

旁注：您还可以将第三个参数传递为

&q=4300

，直接从api获取转换后的值

    $json_from = number_format($item_total, 2, '.', '');
    $url = "http://rate-exchange.appspot.com/currency?from='.$json_from.'&to=USD";
    $jsons = @file_get_contents($url);
    $json_data = json_decode($jsons, true);
    $to_cur = $json_data['results'][0];


    $data['PAYMENTREQUEST_0_ITEMAMT'] = $to_curr;
    $data['PAYMENTREQUEST_0_AMT'] = $to_curr;

您的输入是什么？你期望得到什么结果？@Rikesh:看到这个问题了吗？这个方法正确吗<代码>$url=”http://rate-exchange.appspot.com/currency?from=INR&to=USD&q=$json_from”是，它是正确的。我已经更新了我的演示，请检查。

    $json_from = number_format($item_total, 2, '.', '');
    $url = "http://rate-exchange.appspot.com/currency?from='.$json_from.'&to=USD";
    $jsons = @file_get_contents($url);
    $json_data = json_decode($jsons, true);
    $to_cur = $json_data['results'][0];


    $data['PAYMENTREQUEST_0_ITEMAMT'] = $to_curr;
    $data['PAYMENTREQUEST_0_AMT'] = $to_curr;
