Question

尝试从使用PHP NumberFormatter格式化的货币中删除最后一个.00但似乎不可能。我可以看到此选项，但它似乎不会影响货币：DECIMAL_ALWAYS_SHOWN

$nf = new \NumberFormatter('en_US', \NumberFormatter::CURRENCY);
$nf->formatCurrency(0, 'EUR');
// Output is €0.00 but it doesn't seem possible to remove the .00

我会为.00做一个str_replace，但这可能会有所不同，具体取决于区域设置，所以看起来并不那么容易。

Answer 1

您只能使用format()方法强制执行此操作：

$nf = new \NumberFormatter('en_US', \NumberFormatter::CURRENCY);
$nf->setTextAttribute(\NumberFormatter::CURRENCY_CODE, 'EUR');
$nf->setAttribute(\NumberFormatter::MAX_FRACTION_DIGITS, 0);
echo $nf->format(1);

Answer 2

试试这个：

$nf = new \NumberFormatter('en_US', \NumberFormatter::CURRENCY);
$nf->formatCurrency(0, 'EUR');
numfmt_set_attribute($nf, \NumberFormatter::MAX_FRACTION_DIGITS, 0);
echo numfmt_format($nf, 123.00)."\n";

Answer 3

如果您只想删除.00，并希望保留.00以外的其他内容，则可以尝试：

$formatter = new \NumberFormatter('en_US', \NumberFormatter::CURRENCY);
$money =  $formatter->formatCurrency($money, 'USD');
$money = rtrim($money,".00");

如果您希望将所有这些数字四舍五入到小数点后，则可以添加round：

$formatter = new \NumberFormatter('en_US', \NumberFormatter::CURRENCY);
$money =  $formatter->formatCurrency(round($money,0), 'USD');

如果您分别需要较低和较高的值，也可以使用floor和ceil代替回合。

<?php

declare(strict_types=1);

/**
 * Format a float value into a formatted number with currency,
 * depending on the locale and the currency code.
 */
function customCurrencyFormatter(float $value, ?string $locale = 'en_US', ?string $currencyCode = 'EUR'): string {
    // Init number formatter and its default settings.
    $nf = new \NumberFormatter($locale ?? Locale::getDefault(), \NumberFormatter::CURRENCY);
    $nf->setTextAttribute(\NumberFormatter::CURRENCY_CODE, $currencyCode);

    // Apply number rules. Here, we round it at the number of decimals 
    // we want to display on non-integer values. 
    // Examples.
    //   2 decimals: 1.949 -> 1.95
    //   3 decimals: 1.9485 -> 1.949
    $value = \round($value, $nf->getAttribute(\NumberFormatter::MIN_FRACTION_DIGITS));
    // Detect if the rounded result is an integer value.
    // If so, remove decimals from the formatting.
    if (\intval($value) == $value) {
      $nf->setAttribute(\NumberFormatter::MIN_FRACTION_DIGITS, 0);
    }

    // Convert non-breaking and narrow non-breaking spaces to normal ones.
    return \str_replace(["\xc2\xa0", "\xe2\x80\xaf"], ' ', $nf->format($value));
}


echo customCurrencyFormatter(2.999, 'de_DE', 'USD') . \PHP_EOL;
// 3 $
echo customCurrencyFormatter(2.949, 'de_DE', 'USD') . \PHP_EOL;
// 2,95 $

Answer 5

你不能用round（）来做吗？

echo round($nf, 0)
