From my understanding of Plesk, it is possible to change the global php.ini for the system. But the recommended method is to utilize the vhosts.conf file, because I believe that it's been said that if you edit the global php.ini for the system and then update Plesk that your php.ini file will be overwritten with the default for Plesk. The situation I have is that we have a customer that wants to install ioncube within the php.ini for speed and the fact that it would then work for all domains on the same VPS container. But if it's just going to get wiped out from a Plesk update down the road, this probably wouldn't be a good plan. I know that you can place information in the vhosts.conf file, but that only works on a per domain basis. How do we make changes to the php.ini file so that it affects the global installation without the chances of being overwritten in the future.
