By default, when a virtual server runs PHP scripts as the server's owner, Virtualmin will copy the system's global PHP configuration file (usually `/etc/php.ini`) to the domain's `~/etc` directory. This allows PHP options to be set differently on a per-server basis.

This setting can be used to enter a different path for the base PHP configuration file to copy. In addition, you can use Virtualmin substitutions like ${DOM} in this template file, which will be replaced when it is copied. Other useful substitutions available include :

`${DOM}` | The domain name, such as `foo.com`
`${USER}` | The server's administration login, such as `foo`
`${HOME}` | The server's home directory, like `/home/foo`
`${EMAILTO}` | The virtual server's contact email address

In addition, conditional blocks like ${IF-MAIL}...${ENDIF-MAIL} and ${IF-WEB}...${ELSE-WEB}...{$ENDIF-WEB} may be used.
