How do I remove PHP 7 Completely?

I have upgraded PHP old version to latest php7 but unable to start its services.

systemctl restart apache2.service
Job for apache2.service failed. See "systemctl status apache2.service" and "journalctl -xe" for details.

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

sudo apt-get purge php7.*

As I have answered your question Unable to locate package php7.0 and you have accepted my answer and because you explicitly ask for a removal of the package:

sudo apt-get install ppa-purge
sudo ppa-purge ppa:ondrej/php-7.0

If you run Abhishek's it will remove other packages. On mine it was going to remove these too

The following packages will be REMOVED

libapache2-mod-php5.5* libapache2-mod-php5.6* php-common* php-gettext* php-igbinary* php-memcached* php-msgpack* php-pear* php-xdebug* php5-cli*
php5-common* php5-dev* php5-json* php5-memcache* php5-memcached*
php5-readline* php5-redis* php5-xdebug* php5.5-cli* php5.5-common*
php5.5-curl* php5.5-json* php5.5-mysql* php5.5-opcache* php5.5-readline* php5.5-xml* php5.6* php5.6-cli* php5.6-common* php5.6-curl* php5.6-fpm* php5.6-json* php5.6-mbstring* php5.6-mysql* php5.6-opcache* php5.6-readline* php5.6-xml* pkg-php-tools*

So you're better off with

sudo apt-get purge php7.*

The way to remove PHP and dependencies is:

apt-get autoremove php7.0

to remove php7.x simpely use

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

After doing a:

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

Then do a:

whereis php

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

sudo rm -rf /etc/php
