I want to use Moodle, but I get an error during the installation process:

> 
> php\_extension->intl->should be installed and enabled for best results.
> 
> 
> Intl extension is used to improve internationalization support, such as locale aware sorting.
> 
> 
> 

When I click on the link, I get the error message above: `http://docs.moodle.org/24/en/admin/environment/php_extension/intl`

I followed that link, but I still get the same error. If anyone has any ideas, please help me out.
