NumberFormatter::PUBLIC_RULESETS
.

Attribute specifier - one of the text attribute constants.
Return attribute value on success, or false

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";
?>
以上例程会输出:
Prefix: - -1.234.567,891 Prefix: MINUS MINUS1.234.567,891
