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";
?>
以上例程会输出：
Pattern: #,##0.### 1.234.567,891 Pattern: #0.# kg 1234567,9 kg
