You can install multiple PHP versions and then work with the one you need.

You have to switch the version

Remember to check if php8 necessary packages is already installed:

sudo apt-get install php8.0 php8.0-common php8.0-cli php8.0-fpm php8.0-mysql php8.0-curl php8.0-gd php8.0-bcmath php8.0-mbstring php8.0-zip

And to switch the version you can try the following commands:

sudo apt-get remove php8.1
sudo update-alternatives --set php /usr/bin/php8.0
sudo service apache2 restart
