One Main php.ini For All Virtual Servers

Hello guys,

I would like to change Loaded Configuration File for all virtual servers, and /etc/php5/cgi/php.ini to become main php.ini for all virtual servers. Is this possible?

Currently phpinfo() showing like this:

Configuration File (php.ini) Path /etc/php5/cgi

Loaded Configuration File /home/domainname.com/etc/php5/php.ini

Thanks for helping in advance

If anybody would need in the future

Webmin -> Others -> PHP Configuration
