While I know that php 8 is the default PHP choice on Ubuntu 22.04, I still use php 7 for my project. When installing packages related to PHP, the dependancies always pick php-common, php-*, etc.. and end up installing php 8 on the server.

Currently I have trouble installing Composer via apt install composer

So how do I tell the system that php-* is always mapped to php7.4-* and force libraries to always pick this given php version?

PHP7 is no longer available in the core repository of Ubuntu 22.04, but you can install it using the PPA documented at https://launchpad.net/~ondrej/+archive/ubuntu/php/

To add support for older php version to be installed:

add-apt-repository ppa:ondrej/php && apt update -y

AFter you install the php7.4 packages you need, the following command will prompt you to select the default php version:

sudo update-alternatives --config php
