从 formatCurrency 中删除货币符号

Question

我正在尝试格式化从数据库中获取的收入总额，并使用 php 的 NumberFormatter class 和 formatCurrency 方法。

但是，我不想用它打印出实际的 € / 欧元符号。我只想要纯数字，带逗号和小数点。

示例； 1234.56 应格式化为 1,234.56 当前输出为 1,234.56 欧元。

我使用的代码：

$array['total_revenue'] = $this
    ->db
    ->query($sql)
    ->row_array()['SUM( booking_total )'];

$formatter = new NumberFormatter('en_GB',  NumberFormatter::CURRENCY);

echo $formatter->formatCurrency($array['total_revenue'], 'EUR') . PHP_EOL;

谁能告诉我如何解决这个问题以删除欧元符号？

Answer 1

一个简单的正则表达式可以快速解决您的问题。尝试；

$actual = $formatter->formatCurrency($array['total_revenue'], 'EUR') . PHP_EOL;
$output = preg_replace( '/[^0-9,"."]/', '', $actual );
echo $output;

希望对您有所帮助

Answer 2

您应该使用 setSymbol() 函数：

$formatter = new NumberFormatter('en_GB',  NumberFormatter::CURRENCY);
$formatter->setSymbol(NumberFormatter::CURRENCY_SYMBOL, '');
echo $formatter->formatCurrency($array['total_revenue'], 'EUR') . PHP_EOL;

Answer 3

我来这里是因为出于某种原因，$formatter->setSymbol(NumberFormatter::CURRENCY_SYMBOL, ''); 被 $formatter->formatCurrency($array['total_revenue'], 'USD');

忽略了

为了解决这个问题，我在这里找到了解决方案。 https://www.php.net/manual/en/numberformatter.setsymbol.php#124153

this could be obvious to some, but setSymbol(NumberFormatter::CURRENCY_SYMBOL, '') doesn't work for formatCurrency - it will simply be ignored...

use NumberFormatter::CURRENCY and $fmt->format(123); to get a currency value with the symbol specified as CURRENCY_SYMBOL (or INTL_CURRENCY_SYMBOL)

即

    $fmt = new NumberFormatter('de_DE', NumberFormatter::CURRENCY);
    $fmt->setSymbol(NumberFormatter::CURRENCY_SYMBOL, '');
    $fmt->setAttribute(NumberFormatter::FRACTION_DIGITS, 2);
    echo $fmt->format(56868993064.7985);
    //Output: 56.868.993.064,80
