示例

示例 #1 numfmt_format() example

<?php
$fmt = numfmt_create( 'de_DE', NumberFormatter::DECIMAL );
$data = numfmt_format($fmt, 1234567.891234567890000);
var_dump($data);
?>

示例 #2 OO example

注释

注意:

Formats achievable by this method of formatting cannot fully use the possibilities of underlying ICU library, such as to format currency with narrow currency symbol.

To fully utilize them use msgfmt_format_message().
