There are 4 php terms in Kloxo-MR. One of them is 'php branch' and others are 'multiple php', 'secondary php' and 'php used'.
Because Kloxo-MR 7.0 can handle multiple php where every website using different php version. For this situation, we need to set 'default php'. For php-fpm, this 'default php' set via 'php used'. For non php-fpm (only possible in apache; like suphp), 'default php' is 'php branch'.
If we list php via 'yum list php*' we can see various php like php54, php56u and so on. This various php are 'php branch' and install to server via 'yum install'.
Difference with 'php branch', 'multiple php' installed via 'special' treatment (may different trick for each control panel). This 'multple php' (only under php-fpm; remember web servers except apache always use php-fpm) may possible use for every website with select via 'php selected' in 'web features' (in php-fpm) or via modified .htaccess file for apache (non php-fpm; aka php-cgi).
