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
