Step by Step: Upgrade to PHP8.2 on Ubuntu 20
Upgrading to PHP 8.2 on Ubuntu 20.04 can be done in a few simple steps. Here’s a step-by-step guide to getting you started:
- First, you’ll need to make sure that you have all the necessary dependencies installed on your Ubuntu system. You can do this by running the following command:
sudo apt-get update && sudo apt-get install software-properties-common
This will update the list of available packages and install the software-properties-common package, which is needed to add the PPA for PHP 8.2.
- Next, you’ll need to add the PPA for PHP 8.2 by running the following command:
sudo add-apt-repository ppa:ondrej/php
This will add the PPA for PHP 8.2 to your system.
- Once the PPA has been added, you’ll need to update the package list again by running the following command:
sudo apt-get update
- Now you can install PHP 8.2 by running the following command:
sudo apt-get install php8.2
This will install the PHP 8.2 packages and any necessary dependencies.
- After the installation is complete, you’ll need to verify that PHP 8.2 is now the active version on your system by running the following command:
php -v
This will display the version of PHP that’s currently active on your system.
- If you want to make sure that the Apache web server is using the new version of PHP you need to run:
sudo a2enmod php8.2
sudo service apache2 restart
- Finally, you’ll want to check if all your PHP extensions are compatible with the new version of PHP and install any missing extensions that you need by running
sudo apt-get install php8.2-{extension-name}
Now you should have successfully upgraded to PHP 8.2 on your Ubuntu 20.04 system. It’s highly recommended to thoroughly test your application for compatibility before going live.
Note: This guide assumes you have an Apache web server installed on your system, if you have Nginx, you should use nginx specific commands for enabling PHP and restart the server.
