The Intl (Internationalization) extension in PHP provides localization-related functions

The Intl (Internationalization) extension in PHP provides localization-related functions, such as formatting dates, numbers, and currencies according to locale. This extension is included by default but needs to be enabled in the `php.ini` file. Uncomment the line `;extension=intl`, then restart your web server to use Intl functions.

Already included with PHP.
