Rule-based formatters only understand NumberFormatter::DEFAULT_RULESET and NumberFormatter::PUBLIC_RULESETS.

范例

示例 #1 numfmt_set_text_attribute() example

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