过程化风格
numfmt_set_text_attribute(NumberFormatter$formatter, int $attribute, string $value): bool
Set 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.
-
value -
Text for the attribute value.
返回值
成功时返回 true， 或者在失败时返回 false。
范例
示例 #1 numfmt_set_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";
?>
以上例程会输出：
Prefix: - -1.234.567,891 Prefix: MINUS MINUS1.234.567,891
