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().

on Linux you may need to install icu-data-full package for NumberFormatter to work properly with non-english locales.备份地址：http://www.lvesu.com/blog/php/numberformatter.format.php
