public NumberFormatter::getSymbol(int `$symbol`): string|false

过程化风格

numfmt_get_symbol(NumberFormatter `$formatter`, int `$symbol`): string|false

### 参数

`formatter`

  NumberFormatter object.

`symbol`

  Symbol specifier, one of the format symbol constants.

### 返回值

The symbol string or `false` on error.

### 示例

示例 #1 numfmt_get_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
