# Update domain's PHP values

This function allows WHM's
MultiPHP Manager
interface (WHM >> Home >> Software >> MultiPHP Manager) to change the values of a domain.

Important:

When you disable the
Web Server role,
the system disables this function.

Warning:

We strongly recommend that you only activate Apache PHP-FPM if your server has at
least 2 GB of RAM available, or at least 30 MB of RAM per domain. If you enable PHP-FPM
on a server with less than the required RAM, your server may experience severe
performance issues.
