PHP NumberFormatter和货币，无法设置精度 [英] PHP NumberFormatter and Currency, can't set precision

问题描述

使用 NumberFormatter PHP类(来自国际扩展).但是我得到了一些奇怪的结果.在这里:

I want to set a precision of 0 when using the NumberFormatter PHP class (from Intl extension) with currency. However I've got some strange result. Here:

$numberFormatter = new NumberFormatter('en-US', NumberFormatter::CURRENCY);
$numberFormatter->setAttribute(NumberFormatter::FRACTION_DIGITS, 0);

echo $numberFormatter->formatCurrency('45', 'USD');

它输出$45，这是我想要的.但是，如果我使用相同的设置将货币更改为EUR:

It outputs $45, which is what I want. However, if I change the currency to EUR with the same settings:

echo $numberFormatter->formatCurrency('45', 'EUR');

它输出€45.00(尽管我明确设置为精度为零).

It outputs €45.00 (although I explicitly set to have a precision of zero).

更奇怪的是，如果我将语言环境设置为fr-FR，它将按预期输出数字:

Even more strange, if I set the locale to fr-FR, it outputs the number as expected:

$numberFormatter = new NumberFormatter('fr-FR', NumberFormatter::CURRENCY);
$numberFormatter->setAttribute(NumberFormatter::FRACTION_DIGITS, 0);

echo $numberFormatter->formatCurrency('45', 'EUR');

它输出45 €.

这是一个错误吗?

我确认这是4.4.x分支中的ICU错误.
考虑升级libicu，4.8.x会给出正确的结果
