php - paypal php sdk 在上线时出现 float 问题

Question

我正在使用 paypal rest api 为 woocommerce 编写自定义 paypal 网关。我几乎完成了，在使用沙盒帐户进行测试时一切正常。但是切换到 Live 后，我得到了很多错误“货币金额必须是非负数”这是我得到的:

PayPal\Core\PayPalHttpConnection : ERROR: Got Http response code 400 when accessing https://api.paypal.com/v1/payments/payment. {"name":"VALIDATION_ERROR","details":[{"field":"transactions[0].item_list.items[0].price","issue":"Currency amount must be non-negative number, contain exactly 2 decimal places separated by '.' (JPY contains 0 decimal places), optional thousands separator ',', limited to 7 digits before the decimal point and currency which is a valid ISO Currency Code"},{"field":"transactions[0].amount.details.subtotal","issue":"Currency amount must be non-negative number, contain exactly 2 decimal places separated by '.' (JPY contains 0 decimal places), optional thousands separator ',', limited to 7 digits before the decimal point and currency which is a valid ISO Currency Code"},{"field":"transactions[0].amount.total","issue":"Currency amount must be non-negative number, contain exactly 2 decimal places separated by '.' (JPY contains 0 decimal places), optional thousands separator ',', limited to 7 digits before the decimal point and currency which is a valid ISO Currency Code"}],"message":"Invalid request - see details","information_link":"https://developer.paypal.com/docs/api/payments/#errors","debug_id":"dc60e0012af71"}

我觉得问题出在这里:

if ($dec == 0) $myprice = ceil($myprice);
            else $myprice = round($myprice, $dec);}
            $myprice = doubleval($myprice);
            return $myprice ;

当我将 $myprice 的值更改为一个整数时，它工作正常，但它不起作用。即使使用 Number_format 问题也是一样的。有人可以帮帮我吗？

我的猜测是您传递的值不符合 paypal 要求的格式。很可能是小数分隔符，由不同的区域设置或其他原因引起。
