Ubuntu – How to switch from php v8.0 to v8.1

I am using an ubuntu digitalocean droplet as a web application server. I have 2 active applications that require php8.0 and above but I want to deploy a third application that requires php8.1.

I have installed php8.1 and edited my nginx configuration for each application to usephp8.1. Ran php -v command and the active version is still php8.0

How can I switch to php8.1?

    Your default PHP 8.0:

    php -v

    Run installed PHP 8.1:

    /usr/bin/php8.1 -v

    You can switch active version by:

    sudo update-alternatives --config php

    Output

    There are 2 choices for the alternative php (providing /usr/bin/php).

  Selection    Path             Priority   Status
------------------------------------------------------------
  0            /usr/bin/php8.0   80        auto mode
  1            /usr/bin/php8.1   70        manual mode
* 2            /usr/bin/php8.0   80        manual mode

Press <enter> to keep the current choice[*], or type selection number: 1
update-alternatives: using /usr/bin/php8.1 to provide /usr/bin/php (php) in manual mode
