Issues with NumberFormatter

Good day every one, am currently testing a full blown system build on codeigniter 4, i got the error on NumberFormatter i contacted the host, and they said the lib is no longer maintained, so they disabled it. is the an alternative to this lib NumberFormatter

The NumberFormatter is part of the internationalization extension (intl) ... http://php.net/manual/en/class.numberformatter.php

Some hosts don't have it enabled, but they should once prompted.

I could not find any suggestions online that it might be no longer maintained

OK thanks
