I have managed to set up multiple versions of PHP (5.x and 7.0) on a test server (Ub. 12.04) under V.min with latest W.min V5.0 update. I have symlinked the PHPBrew PHP installation folders to appropriate subfolders in /opt/rh/. V.min then recognises the various versions of PHP and permits switching virtual servers between those versions of PHP, as proven by the ouput from phpinfo().
However there appears to be no obvious method for managing separate php.ini files for each virtual server as the "non-native" versions of PHP load the version of php.ini found within their own phpbrew folder, irrespective of what V.min reports as being the active php.ini file for the server in Services > PHP 5 Configuration.
What is the best practice when it comes to managing PHP config files in this situation?
