Fatal error: Call to undefined function money_format()
提问by user3201312
Every time I try to run this code there is a message saying:
每次我尝试运行此代码时，都会有一条消息说：
Fatal error: Call to undefined function money_format()
The lines that have that problem are:
有这个问题的行是：
$pricetotal = money_format("%10.2n", $pricetotal);
and
和
$cartTotal = money_format("%10.2n", $cartTotal);
Can you please explain me the reason why this happens ?
你能解释一下发生这种情况的原因吗？

if you are using windows based system then you will not have this function available.
如果您使用的是基于 Windows 的系统，那么您将无法使用此功能。
The function money_format() is only defined if the system has strfmon capabilities. For example, Windows does not, so money_format() is undefined in Windows.
函数 money_format() 仅在系统具有 strfmon 功能时才定义。例如，Windows 没有，因此money_format() 在Windows 中是未定义的。
(this has been pointed out by Mike W in comments as well)
（Mike W 在评论中也指出了这一点）

It has been pointed out that you may not have this function because it does not exist on all operating systems (see Mike W's comment or Learner Student's answer).
有人指出，您可能没有此功能，因为它并非在所有操作系统上都存在（请参阅 Mike W 的评论或 Learner Student 的回答）。
Since the function appears absent on your system, you can write your own function based on the number_format function. You appear to want to format the number as US dollars, so the default (decimal = .and thousands = ,should work for you).
由于该函数在您的系统中不存在，您可以根据number_format 函数编写自己的函数。您似乎想要将数字格式化为美元，因此默认值（十进制 =.和千位 =,应该适合您）。
function asDollars($value) {
if ($value<0) return "-".asDollars(-$value);
return '$' . number_format($value, 2);
}
Then you can replace
然后你可以更换
$pricetotal = money_format("%10.2n", $pricetotal);
with
和
$pricetotal = asDollars($pricetotal);
The updated code puts the negative sign in front of the currency sign even for negative numbers (per the comment by @kunal).
更新后的代码即使对于负数也将负号放在货币符号前面（根据@kunal 的评论）。
