In this guide we will learn how to install PHP on Ubuntu 22.04 Linux operating system. PHP is known scripting language, which was designed for building websites. PHP language can be used on many platforms such Linux, Windows, Mac OS, and Unix. On this tutorial, we will use the latest version of PHP (version 8.1). This version serves as an extension of PHP version 8.0. PHP version 8.1 presenet with many features which were not present in the previous one such as enums, read-only properties, never return type, fibers, etc.
Installing PHP 8.1 On Ubuntu 22.04 LTS
In this tutorial we will use the Ondrej PPA for installing PHP on Ubuntu 22.04 LTS system, this tutorial is also compatible with Ubuntu 20.04 LTS, and 18.04 LTS.
Prerequisite
As mentioned above, we will install the latest version of PHP (version 8.1.3, at least at the time this tutorial was written). Before we start to install PHP 8.1 on Ubuntu 22.o4 LTS operating system, there are several prerequisites that must be met so that the installation process can be running smoothly. We will need to prepare any requirements as mention below :
1. an Ubuntu 22.04 server system
ramans@infodiginet:~$ hostnamectl Static hostname: infodiginet Icon name: computer-vm Chassis: vm Machine ID: c05bdac4b09048309a26b6024adee484 Boot ID: ba10ca2fa4c348bc816932582a0222ad Virtualization: vmware Operating System: Ubuntu 22.04.1 LTS Kernel: Linux 6.0.0-060000-generic Architecture: x86-64
2. non-root user with sudo privileges
3. sufficient disk and good internet access
PHP 8.1 Installation Process
To install PHP on Ubuntu systems, we only need to add the required PPA and we can install any PHP version. The PHP 8.1 installation process will be explained in this tutorial are as follows :
- Update System
- Install dependency packages
- Add Ondrej PPA
- Install PHP
- Switch Default PHP version
Explanation of each step will be mentioned in the following sub-chapters.
1. Update System
The first step to be taken in PHP installation is to update local packages repository. This task will cut down the installation time and it also helps prevent zero-day exploits against outdated software, for this purpose we will submit the command line :
$ sudo apt update $ sudo apt upgrade
2. Install Dependencies Packages
To install PHP, we need a dependencies packages on our system, for this purpose we will submit following command line :
$ sudo apt install software-properties-common apt-transport-https -y
Output :
ramans@infodiginet:~$ sudo apt install software-properties-common apt-transport-https -y Reading package lists... Done Building dependency tree... Done Reading state information... Done apt-transport-https is already the newest version (2.4.8). The following additional packages will be installed: python3-software-properties software-properties-gtk The following packages will be upgraded: python3-software-properties software-properties-common software-properties-gtk 3 upgraded, 0 newly installed, 0 to remove and 54 not upgraded.

3. Add the Ondrej PPA
In this step we will add Ondrej PPA which contains all versions of PHP packages for the Ubuntu systems. This task will be performed by submitting ommand line :
$ sudo add-apt-repository ppa:ondrej/php -y
Output :
ramans@infodiginet:~$ sudo add-apt-repository ppa:ondrej/php -y 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.

4. Installing PHP
In this step we will install PHP on Ubuntu 22.04 system, before it we will update our Ubuntu 22.04 system by submitting command line :
$ sudo apt update
4.1. Install PHP 8.1
In this step, we will install PHP on our system. In this tutorial we will install PHP version 8.1, so we will submit the following command line :
$ sudo apt -y install php8.1
Output :
ramans@infodiginet:~$ sudo apt -y install php8.1 Reading package lists... Done Building dependency tree... Done Reading state information... Done The following additional packages will be installed: libapache2-mod-php8.1 php8.1-cli php8.1-common php8.1-opcache php8.1-readline Suggested packages: php-pear The following NEW packages will be installed: libapache2-mod-php8.1 php8.1 php8.1-cli php8.1-common php8.1-opcache php8.1-readline 0 upgraded, 6 newly installed, 0 to remove and 58 not upgraded.

Then we will verify by querying its version, by submitting command line :
$ php --version
Output :

4.2. Install PHP 7.4
PHP version 7.4 is still widely used and is the most popular among other PHP 7 versions. To install PHP 7.4, we use the command line:
$ sudo apt -y install php7.4
Output :
ramans@infodiginet:~$ sudo apt -y install php7.4 Reading package lists... Done Building dependency tree... Done Reading state information... Done The following additional packages will be installed: libapache2-mod-php7.4 php-common php7.4-cli php7.4-common php7.4-json php7.4-opcache php7.4-readline Suggested packages: php-pear The following NEW packages will be installed: libapache2-mod-php7.4 php-common php7.4 php7.4-cli php7.4-common php7.4-json php7.4-opcache php7.4-readline 0 upgraded, 8 newly installed, 0 to remove and 58 not upgraded.

Then we will verify it by submitting command line :
$ php --version
Output :
ramans@infodiginet:~$ php --version PHP 7.4.33 (cli) (built: Jan 6 2023 16:10:54) ( NTS ) Copyright (c) The PHP Group Zend Engine v3.4.0, Copyright (c) Zend Technologies with Zend OPcache v7.4.33, Copyright (c), by Zend Technologies
5. Switch Default PHP Version
In this step we will try to switch PHP version for CLI and Apache. We will show you how to switch among PHP version by using command line :
$ sudo update-alternatives --config php
Output :
ramans@infodiginet:~$ sudo update-alternatives --config php There are 2 choices for the alternative php (providing /usr/bin/php). Selection Path Priority Status ------------------------------------------------------------ * 0 /usr/bin/php8.1 81 auto mode 1 /usr/bin/php7.4 74 manual mode 2 /usr/bin/php8.1 81 manual mode Press <enter> to keep the current choice[*], or type selection number: 1 update-alternatives: using /usr/bin/php7.4 to provide /usr/bin/php (php) in manual mode ramans@infodiginet:~$ sudo update-alternatives --config php There are 2 choices for the alternative php (providing /usr/bin/php). Selection Path Priority Status ------------------------------------------------------------ 0 /usr/bin/php8.1 81 auto mode * 1 /usr/bin/php7.4 74 manual mode 2 /usr/bin/php8.1 81 manual mode
Conclusion
In this tutorial we have learned about the instructions to install PHP on Ubuntu 22.04. Using of Ondrej PPA allows us to quickly install PHP on Ubuntu systems install multiple PHP versions on a single system. We can switch between PHP version as default anytime with the update-alternative utility.
