Answer 1

I think you should try this

From php5.6 to php7.1

sudo a2dismod php5.6
sudo a2enmod php7.1
sudo service apache2 restart

sudo update-alternatives --set php /usr/bin/php7.1
sudo update-alternatives --set phar /usr/bin/phar7.1
sudo update-alternatives --set phar.phar /usr/bin/phar.phar7.1

From php7.1 to php5.6

sudo a2dismod php7.1
sudo a2enmod php5.6
sudo service apache2 restart

sudo update-alternatives --set php /usr/bin/php5.6
sudo update-alternatives --set phar /usr/bin/phar5.6
sudo update-alternatives --set phar.phar /usr/bin/phar.phar5.6
