# Once we have PHP 5.6 (or 5.5) and 7.0 installed, we can easily switch between them from the shell using these commands. To enable PHP 5.6 (and disable PHP 7.0) use this command:
sudo a2dismod php7.0 ; sudo a2enmod php5.6 ; sudo service apache2 restart ; echo 1 | sudo update-alternatives --config php
# Similarly, to switch from PHP 5.6 to PHP 7.0, use this command:
sudo a2dismod php5.6 ; sudo a2enmod php7.0 ; sudo service apache2 restart ; echo 2 | sudo update-alternatives --config php
# Or, better yet, why not set up a couple of simple Bash aliases in your .bashrc to take care of this for you:
alias phpv5='sudo a2dismod php7.0 ; sudo a2enmod php5.6 ; sudo service apache2 restart ; echo 1 | sudo update-alternatives --config php'
alias phpv7='sudo a2dismod php5.6 ; sudo a2enmod php7.0 ; sudo service apache2 restart ; echo 2 | sudo update-alternatives --config php'
