示例

示例 #1 numfmt_parse() example

<?php
$fmt = numfmt_create( 'de_DE', NumberFormatter::DECIMAL );
$num = "1.234.567,891";
echo numfmt_parse($fmt, $num)."\n";
echo numfmt_parse($fmt, $num, NumberFormatter::TYPE_INT32)."\n";
?>

示例 #2 OO example

<?php
$fmt = new NumberFormatter( 'de_DE', NumberFormatter::DECIMAL );
$num = "1.234.567,891";
echo $fmt->parse($num)."\n";
echo $fmt->parse($num, NumberFormatter::TYPE_INT32)."\n";
?>

以上示例会输出：

1234567.891
1234567
