How can I change the PHP version used in console on Ubuntu 20.04? I have all versions in the /etc/php folder, but I don't know where the configuration for the command line version is.

command-line

  1. You can do this with update-alternatives. If you would like to do this interactively, you can do this:

    sudo update-alternatives --config php

    If you like to specifically choose the PHP version (via an alias or whatnot), you can do this:

    sudo update-alternatives --set php /usr/bin/php7.4

    Of course, be sure to change php7.4 to the actual version you want to switch between.

  4. alias setphp="sudo update-alternatives --config php;sudo update-alternatives --config phar; update-alternatives --config phar.phar; a2dismod php*.*;systemctl restart apache2"

    Put the above alias in ~/.bashrc:

    sudo nano ~/.bashrc

    Then just run this command:

    a2enmod php<Your Desired Version> # like, a2enmod php7.4

    Now you can run the command setphp from your terminal.
