How do I remove PHP 7 Completely?

• systemctl restart apache2.service
• systemctl status apache2.service

To remove php7.0 use

• sudo apt-get purge php7.0-common

This will remove all php7 version, be it php 7.0 or php 7.1 etc..

• sudo apt-get purge php7.*
• apt-get autoremove php7.0
• sudo apt-get purge `dpkg -l | grep php7.2| awk '{print $2}' |tr "\n" " "`
• sudo apt-get purge php7.*

to remove all versions of php7, you still need to run some extra steps to completely and utterly remove php7:

• sudo apt-get autoremove --purge
• whereis php

and then remove all directories in the output of the last command, E.G.:

sudo rm -rf /etc/php
