示例 #1 numfmt_set_attribute() example
<?php
$fmt = numfmt_create( 'de_DE', NumberFormatter::DECIMAL );
echo "Digits: ".numfmt_get_attribute($fmt, NumberFormatter::MAX_FRACTION_DIGITS)."\n";
echo numfmt_format($fmt, 1234567.891234567890000)."\n";
numfmt_set_attribute($fmt, NumberFormatter::MAX_FRACTION_DIGITS, 2);
echo "Digits: ".numfmt_get_attribute($fmt, NumberFormatter::MAX_FRACTION_DIGITS)."\n";
echo numfmt_format($fmt, 1234567.891234567890000)."\n";
?>示例 #2 OO example
<?php
$fmt = new NumberFormatter( 'de_DE', NumberFormatter::DECIMAL );
echo "Digits: ".$fmt->getAttribute(NumberFormatter::MAX_FRACTION_DIGITS)."\n";
echo $fmt->format(1234567.891234567890000)."\n";
$fmt->setAttribute(NumberFormatter::MAX_FRACTION_DIGITS, 2);
echo "Digits: ".$fmt->getAttribute(NumberFormatter::MAX_FRACTION_DIGITS)."\n";
echo $fmt->format(1234567.891234567890000)."\n";
?>以上示例会输出：
