public NumberFormatter::setSymbol(int $symbol, string $value): bool

过程化风格

numfmt_set_symbol(NumberFormatter $formatter, int $symbol, string $value): bool

Set a symbol associated with the formatter. The formatter uses symbols to represent the special locale-dependent characters in a number, for example the percent sign. This API is not supported for rule-based formatters.

参数

formatter: NumberFormatter object.
symbol: Symbol specifier, one of the format symbol constants.
value: Text for the symbol.

返回值

成功时返回 true，或者在失败时返回 false。

示例

示例 #1 numfmt_set_symbol() example

<?php
$fmt = numfmt_create( 'de_DE', NumberFormatter::DECIMAL );
echo "Sep: ".numfmt_get_symbol($fmt, NumberFormatter::GROUPING_SEPARATOR_SYMBOL)."\n";
echo numfmt_format($fmt, 1234567.891234567890000)."\n";
numfmt_set_symbol($fmt, NumberFormatter::GROUPING_SEPARATOR_SYMBOL, "*");
echo "Sep: ".numfmt_get_symbol($fmt, NumberFormatter::GROUPING_SEPARATOR_SYMBOL)."\n";
echo numfmt_format($fmt, 1234567.891234567890000)."\n";
?>

示例 #2 OO example

<?php
$fmt = new NumberFormatter( 'de_DE', NumberFormatter::DECIMAL );
echo "Sep: ".$fmt->getSymbol(NumberFormatter::GROUPING_SEPARATOR_SYMBOL)."\n";
echo $fmt->format(1234567.891234567890000)."\n";
$fmt->setSymbol(NumberFormatter::GROUPING_SEPARATOR_SYMBOL, "*");
echo "Sep: ".$fmt->getSymbol(NumberFormatter::GROUPING_SEPARATOR_SYMBOL)."\n";
echo $fmt->format(1234567.891234567890000)."\n";
?>

以上示例会输出：

Sep: .
1.234.567,891
Sep: *
1*234*567,891

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`)
