How to Upgrade PHP 8.2 to 8.3 in Ubuntu

Step 1: Verify Your Current PHP Version

Before proceeding with the upgrade, it’s important to confirm that the PHP version has been installed and is running on your system. Open the terminal and execute the following command:

php -v

This command will display the version of PHP currently active on your system. If the output indicates PHP 8.2, you’re ready to begin the upgrade process. Verifying your current PHP version helps ensure compatibility with existing configurations and installed extensions.

Step 2: Add the PHP PPA Repository

PHP 8.3 packages are available through the Ondřej Surý PPA, a trusted repository frequently used by developers for accessing updated PHP versions. Adding this repository will give you access to the latest PHP packages. Run the following commands sequentially:

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

The software-properties-common package is required for managing PPAs, and the add-apt-repository command integrates the Ondřej Surý repository into your system. Once the repository is added, you’ll have access to PHP 8.3 and its related packages.

Step 3: Update the Package List

After adding the PHP PPA repository, it’s necessary to refresh your system’s package list to ensure the latest package details are fetched. Execute the following command:

sudo apt update

This step ensures your system is aware of the new repository and its available packages. Skipping this step may result in outdated package lists, which can lead to installation issues.

Step 4: Install PHP 8.3

With the package list updated, you can proceed to install PHP 8.3. Run the following command to install the core PHP package:

sudo apt install -y php8.3

This command installs the main PHP 8.3 package on your system. The -y flag automatically confirms installation prompts, streamlining the process. Once installed, PHP 8.3 is ready for use.

Step 5: Install PHP 8.3 Extensions

Web applications often depend on specific PHP extensions for functionality. To ensure compatibility with your projects, install the necessary extensions for PHP 8.3 by executing the following command:

sudo apt install php8.3-common php8.3-mysql php8.3-xml php8.3-xmlrpc php8.3-curl php8.3-gd php8.3-imagick php8.3-cli php8.3-dev php8.3-imap php8.3-mbstring php8.3-opcache php8.3-soap php8.3-zip php8.3-intl -y

This command includes common extensions such as php8.3-mysql for database interactions, php8.3-xml for XML parsing, and php8.3-curl for handling HTTP requests. Ensure you install only the extensions relevant to your projects to avoid unnecessary clutter on your system.

Step 6: Switch to PHP 8.3

Once PHP 8.3 is installed, you need to make it the default version on your system. Use the update-alternatives command to switch to PHP 8.3:

sudo update-alternatives --set php /usr/bin/php8.3

This command updates the default PHP binary path to point to PHP 8.3. To confirm the change, run the following command:

php -v

The output should now display PHP 8.3 as the active version. This step is crucial for ensuring your system and applications use the upgraded PHP version by default.

Step 7: Restart Your Web Server

After upgrading PHP, it’s important to restart your web server to apply the changes. The command to restart depends on your web server setup:

For Apache:

sudo systemctl restart apache2

For PHP-FPM (if you’re using Nginx):

sudo systemctl restart php8.3-fpm

Restarting your web server ensures that it recognizes and utilizes the newly installed PHP version. Skipping this step might result in your server continuing to use the old PHP version.

Step 8: Remove Older PHP Versions (Optional)

If you no longer need PHP 8.2, you can remove it from your system to free up disk space and avoid potential conflicts. Execute the following commands to uninstall PHP 8.2 and its associated packages:

sudo apt remove -y php8.2
sudo apt autoremove -y

The autoremove command removes unused dependencies installed with PHP 8.2. This step is optional but recommended to keep your system organized and efficient.

Additional Tips for Managing PHP Versions

1. Backup Your Configuration Files: Before making significant changes, backup critical PHP configuration files like php.ini to avoid losing custom settings.
2. Test Your Applications: After upgrading, thoroughly test your applications to ensure they work seamlessly with PHP 8.3.
3. Monitor Performance: Take note of performance improvements or any unexpected behavior after the upgrade.
