Question

我收到以下错误：

警告：number_format（）要求参数1加倍，在第200行.............中给出字符串

请告诉我解决方案。下面我将我的整个代码发布到第200行

Answer 1

在format_price（$ str）或format_int（$ str）中，我会做以下更改：

$result = number_format($str, $decimals, $point, $th_separator);

到

$result = number_format((int)$str, $decimals, $point, $th_separator);

如果数字包含便士使用

$result = number_format((float)$str, $decimals, $point, $th_separator);

警告：number_format（）期望参数1为double，字符串为
