How to remove php 5.6
I just went ahead and added PHP7 to my server following a guide by using ondej's PPA. Now I want to remove the old php so obviously I did sudo apt-get remove --purge php5 and ti seemed like everything went fine except it is not uninstalled. If I do php -v I get version 7 but I can still do php5 -v and get 5.6 or php5.6 -v and get the same thing. When I do sudo apt-get remove php5 (or php5.6) now I get that the package is not installed, but apparently is since I can execute the command.
x@x-server:~$ php -v

How can I completely remove php5?
And just because I know someone would ask - I want to remove it because I see that there are some processes running because of it that I don't want to have.

Package named php5 or php5.6 is just a meta-package that pulls one of the available web SAPIs (apache2, fpm or cgi). The easiest way how to remove full stack of packages is to remove php5-common and/or php5.6-common package as everything else depends on it, e.g.:
apt-get purge php5-common
The other option would be to use wildcard support in apt-get and do:
apt-get purge 'php5*'
