示例

示例 #1 numfmt_set_pattern() example

<?php
$fmt = numfmt_create( 'de_DE', NumberFormatter::DECIMAL );
echo "Pattern: ".numfmt_get_pattern($fmt)."\n";
echo numfmt_format($fmt, 1234567.891234567890000)."\n";
numfmt_set_pattern($fmt, "#0.# kg");
echo "Pattern: ".numfmt_get_pattern($fmt)."\n";
echo numfmt_format($fmt, 1234567.891234567890000)."\n";
?>

示例 #2 OO example

<?php
$fmt = new NumberFormatter( 'de_DE', NumberFormatter::DECIMAL );
echo "Pattern: ".$fmt->getPattern()."\n";
echo $fmt->format(1234567.891234567890000)."\n";
$fmt->setPattern("#0.# kg");
echo "Pattern: ".$fmt->getPattern()."\n";
echo $fmt->format(1234567.891234567890000)."\n";

setPattern appears to influence only the behavior of the format method, not the parse method of the NumberFormatter object. 

$pattern = '#,##0';
$frmtr = NumberFormatter::create('en-US', NumberFormatter::DECIMAL);
$frmtr->setPattern($pattern);
echo $frmtr->parse('12.345');

// returns 12
