Step 2: Add the PHP Repository

To upgrade to PHP 8.2, you need to add the PHP repository to your system. Use the following commands in the terminal to add the repository:

sudo apt install software-properties-common
sudo add-apt-repository ppa:ondrej/php
sudo apt update

Step 4: Verify the PHP Update

After the installation is complete, run the following command to ensure PHP 8.2 is installed:

php -v

Step 5: Install PHP 8.2 Extensions

If your projects require specific PHP extensions, you can install them using the apt package manager. For example:

sudo apt install php8.2

Step 6: Restart the Web Server

If you’re using PHP with a web server like Apache or Nginx, you’ll need to restart the server for the changes to take effect:

sudo service apache2 restart # For Apache
sudo service nginx restart   # For Nginx

Note: If your system still shows an older PHP version, you can use the following command to select the new version from the available options:

sudo update-alternatives --config php

Afterward, recheck the PHP version your web server is using.
