[webmin-l] Why so many php 5.6

[Kimberly <kim...@gm...>]

I set up a server with MariaDB 10.1 and php 5.6 and then install 
Virtualmin; I noticed that Virtualmin alone installed MariaDB 5.5 and I 
figured I would first set up MariaDB before installing Virtualmin.

After Virtualmin install and configuration I see the following:

The following PHP versions are available : 5.6.39 (/bin/php-cgi), 5.6.39 
(/bin/php56-cgi), 7.0.27 (/opt/rh/rh-php70/root/usr/bin/php-cgi), 5.6 
(mod_php)

Why are there so many different php 5.6 listed?
