Droplet console shows php 8.2 and phpinfo functions is showing php 8.0 in browser

I’m trying to run a sage theme on my Wordpress site which requires at least PHP version 8.1.0. When I check php version in droplet console, it shows php version 8.2.6. But when I run phpinfo() function, it shows php version as 8.0.22 in the browser. This is causing my site to break when I activate sage theme on my site. How should I go about making the Wordpress site to run on php 8.1 or above?

When I run phpinfo() function, the ‘Loaded Configuration File’ is ‘/etc/php/8.0/apache2/php.ini’

Now there are 2 other php ini files as well in this directory - ‘/etc/php/’. These are php 8.1 and php 8.2 ini files.

Now I’m not sure how should I go about loading php 8.1 ini file instead of php 8.0 ini file.

The droplet is using Ubuntu 22.04

Thanks in advance for any help on this.
