Hello! I wonder if it is possible to use the same php.ini for all versions of PHP and also PHP-FPM, Fast CGI, CGI, Mod-PHP and SuPHP ... I find it annoying to change all the php.ini in every new change. Thank you very much for your help!
FPM, CGI, Fast-CGI should use the same php.ini already (/etc/php5/cgi/php.ini). I myself use some different settings for the php versions, but if you are sure you don't need that, you could try to replace the /etc/php5/apache2/php.ini with a symlink to the cgi one.
