When you load a website in ISPConfig, it loads a site-specific php.ini file in the client directory tree for that site. How often is this file updated? When the site is saved? Only when PHP version is changed in settings? I'm assuming it copies from the PHP installation location. Is there anyway to push changes back to the site-specific files? Is that even necessary? I guess what I'm asking for is a little insight into how php.ini files are handled by ISPConfig.
