NumberFormatter::getTextAttribute -- numfmt_get_text_attribute — Get a text attribute

### 说明

面向对象风格

public NumberFormatter::getTextAttribute(int `$attribute`): string|false

过程化风格

numfmt_get_text_attribute(NumberFormatter `$formatter`, int `$attribute`): string|false

Get a text attribute associated with the formatter. An example of a text attribute is the suffix for positive numbers. If the formatter does not understand the attribute, `U_UNSUPPORTED_ERROR` error is produced. Rule-based formatters only understand `NumberFormatter::DEFAULT_RULESET` and `NumberFormatter::PUBLIC_RULESETS`.

### 参数

`formatter`

  NumberFormatter object.

`attribute`

  Attribute specifier - one of the text attribute constants.

### 返回值

Return attribute value on success, or `false` on error.

### 示例

示例 #1 numfmt_get_text_attribute() example

`<?php
$fmt = numfmt_create( 'de_DE', NumberFormatter::DECIMAL );
echo "Prefix: ".numfmt_get_text_attribute($fmt, NumberFormatter::NEGATIVE_PREFIX)."\n";
echo numfmt_format($fmt, -1234567.891234567890000)."\n";
numfmt_set_text_attribute($fmt, NumberFormatter::NEGATIVE_PREFIX, "MINUS");
echo "Prefix: ".numfmt_get_text_attribute($fmt, NumberFormatter::NEGATIVE_PREFIX)."\n";
echo numfmt_format($fmt, -1234567.891234567890000)."\n";
?>`

示例 #2 OO example

`<?php
$fmt = new NumberFormatter( 'de_DE', NumberFormatter::DECIMAL );
echo "Prefix: ".$fmt->getTextAttribute(NumberFormatter::NEGATIVE_PREFIX)."\n";
echo $fmt->format(-1234567.891234567890000)."\n";
$fmt->setTextAttribute(NumberFormatter::NEGATIVE_PREFIX, "MINUS");
echo "Prefix: ".$fmt->getTextAttribute(NumberFormatter::NEGATIVE_PREFIX)."\n";
echo $fmt->format(-1234567.891234567890000)."\n";
?>`

以上示例会输出：

    Prefix: -
    -1.234.567,891
    Prefix: MINUS
    MINUS1.234.567,891
