PHP is a popular server scripting language known for creating dynamic and interactive web pages. Getting up and running with your language of choice is the first step in learning to program.
PHP is a general-purpose scripting language suitable for web development. Most websites out there are programmed using PHP language because it is:
- Fast – PHP is fast because it runs on its own memory space. Also, PHP has a Zend engine that parses PHP code and turns it into opcodes which are then interpreted.
- Flexible – PHP is flexible because it allows for almost all databases. MySQL is the de-facto database to connect to because it is open source.
- Free and open source
- PHP is forgiving – Why do we say PHP is forgiving? It is forgiving meaning its learning is not so hard and therefore suitable for almost all programmers starting out.
- PHP supports major communication protocols i.e LDAP, IMAP, and POP3.
Below is a summarised list of the new key features witnessed in the PHP 8.2 release:
nullas Standalone Types
- Disjunctive Normal Form (DNF) Types
- Redact Sensitive Parameters in Back Traces
- Allow Constants in Traits
- New Random Extension
- and Many More
This tutorial will guide you through installing PHP 8.2 on Ubuntu and setting up a local programming environment via the command line.
Install PHP 8.2 on Ubuntu 22.04
1. Run system updates
The first thing to do in a new system is to update our repositories in order to make them up to date. Run upgrade command also.
sudo apt update && apt upgrade -y
2. Add Ondrej sury PPA repository
To run PHP 8.2 on Ubuntu 22.04, we need to add Ondrej sury PPA into our system. This is the maintainer of the PHP repository at the moment. This PPA is not currently checked so installing from it will not be guaranteed 100% results.
To add this PPA use the following command on our terminal.
sudo add-apt-repository ppa:ondrej/php
After installation is complete we need to update the repositories again for the changes to take effect.

sudo apt-get install -y php8.2-cli php8.2-common php8.2-fpm php8.2-mysql php8.2-zip php8.2-gd php8.2-mbstring php8.2-curl php8.2-xml php8.2-bcmath
This command will install the following modules:
php8.2-cli- command interpreter, useful for testing PHP scripts from a shell or performing general shell scripting tasks
php8.2-common- documentation, examples, and common modules for PHP
php8.2-mysql- for working with MySQL databases
php8.2-zip- for working with compressed files
php8.2-gd- for working with images
php8.2-mbstring- used to manage non-ASCII strings
php8.2-curl- lets you make HTTP requests in PHP

PHP configurations related to Apache are stored in
/etc/php/8.2/apache2/php.ini. You can list all loaded PHP modules with the following command:
You have installed PHP and verified the version you have running. You also installed any required PHP modules and were able to list the modules that you have loaded.
