PHP 8.2 is a version of the PHP programming language released near the end of year 2022. This is a major release of PHP that contains many new features, including readonly classes, null, false, and true as stand-alone types, deprecated dynamic properties, performance improvements and more. PHP 8.2 also includes bug fixes and performance improvements over previous versions like 8.1. We recommend you test your codebase with PHP 8.2 before upgrading in a production setup, just to ensure that everything works as expected.
In this article we shall cover steps that are used in the installation of PHP 8.2 on Ubuntu 22.04|20.04|18.04. The default version of PHP available on OS repositories is usually older than PHP official latest releases. PPA (Personal Package Archive) software repositories for PHP allows you to install newer releases of PHP on your Ubuntu system that are not available in the official repositories of a Linux distribution.

Step 1: Update Ubuntu System
Check for updates and install them before performing any other action.
sudo apt update && sudo apt -y upgradeClean APT cache after the upgrade.
sudo apt autoremoveCheck if a reboot is required and act accordingly.
[ -f /var/run/reboot-required ] && sudo reboot -fOS release details can be checked using the commands given here.
$ cat /etc/os-release

Step 2: Add Surý PHP APT repository
To get PHP 8.2 packages installed on Ubuntu we’ll use Ondřej Surý’s PHP PPA which provides the latest stable versions of PHP for Ubuntu and Debian systems.
For Ubuntu 18.04 this repository doesn’t contain PHP 8.2 packages. Checkout our guide on building from source:
Install few dependency packages before adding the repo.
sudo apt update
sudo apt install -y lsb-release gnupg2 ca-certificates apt-transport-https software-properties-commonRun the following commands in your terminal to add Surý PPA to your system.
sudo add-apt-repository ppa:ondrej/php
Expected successful command execution.
PPA publishes dbgsym, you may need to include 'main/debug' component
Repository: 'deb https://ppa.launchpadcontent.net/ondrej/php/ubuntu/ jammy main'
Description:
Co-installable PHP versions: PHP 5.6, PHP 7.x and most requested extensions are included. Only Supported Versions of PHP (http://php.net/supported-versions.php) for Supported Ubuntu Releases (https://wiki.ubuntu.com/Releases) are provided. Don't ask for end-of-life PHP versions or Ubuntu release, they won't be provided.
Debian oldstable and stable packages are provided as well: https://deb.sury.org/#debian-dpa
You can get more information about the packages at https://deb.sury.org
IMPORTANT: The <foo>-backports is now required on older Ubuntu releases.
BUGS&FEATURES: This PPA now has a issue tracker:
https://deb.sury.org/#bug-reporting
CAVEATS:
1. If you are using php-gearman, you need to add ppa:ondrej/pkg-gearman
2. If you are using apache2, you are advised to add ppa:ondrej/apache2
3. If you are using nginx, you are advised to add ppa:ondrej/nginx-mainline
or ppa:ondrej/nginx

Zend OPcacheStep 5: Using PHP with Nginx / Apache
We will consider both Nginx and Apache web server configurations to host your PHP application.
Hosting PHP application with Nginx web server
With Nginx, PHP code is typically executed by a separate process, such as PHP-FPM (FastCGI Process Manager). PHP-FPM is a daemon that listens for incoming PHP requests and runs them in a separate process. Nginx just forwards incoming requests to PHP-FPM where they are executed.
Install Nginx web server and FPM extension.
sudo apt install nginx php8.2-fpmOpen your Nginx server configuration and add the following block inside the http block to configure PHP requests to be forwarded for execution by PHP-FPM:
$ sudo vim /etc/nginx/nginx.conf
server {
listen 80;
server_name mysite.example.com;
root /var/www/mysite;
index index.php index.html;
location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php8.2-fpm.sock;
}
}Validate Nginx configuration is ok.
$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successfulHosting PHP application with Apache web server
In Apache we can use a built-in module called mod_php to process PHP code directly within the Apache process.
But first you need to install Apache web server package, PHP, and Apache PHP extension:
sudo apt install apache2 libapache2-mod-php8.2 Enable mod_php module:
sudo a2enmod php8.2Restart Apache web server after the configuration.
sudo systemctl restart apache2Wrapping up
In conclusion, the installation of PHP 8.2 on Ubuntu 22.04/20.04/18.04 Linux system is a straightforward process. We started with the addition of the Ondřej Surý’s PHP PPA to the system’s package sources, which enabled us to install PHP 8.2 and other modules. Adding third-party PPA to production server can introduce stability and security risks, and they should always be used with caution. If performing PHP upgrade, consider backing up important files before updating your system, just in case something goes wrong during the update process.
