How to Install PHP 8.3 on Ubuntu 22.04(Easy Steps)

In this tutorial, I am going to explain how you can install PHP 8.3 on Ubuntu 22.04. PHP(Hypertext Preprocessor) is the most popular server-side markup language. PHP is the most frequently updated programming language. If you execute the command to install PHP, it may not install the required PHP version. Sometimes we may need to install specific PHP versions, to smoothly run any script or framework.

Step 1: Update Ubuntu Repository

Before installation, update your package manager with the latest release packages from the Ubuntu repository. To update your Ubuntu packages, run the following command.

sudo apt update
sudo apt upgrade

(If you using root access, then you don’t need to add ‘sudo’ before the commands)

Step 2: Add PHP repository to Ubuntu’s repository

By default, PHP 8.3 package files are not available in Ubuntu’s repository. So we need to add Ondrej Sury PPA (PHP all versions packages) into the system. Run the following command first.

sudo apt install ca-certificates apt-transport-https software-properties-common

Once all the packages are installed, add the PPA using the following command.

sudo add-apt-repository ppa:ondrej/php

On successful addition of PPA, again update the repository by following command

sudo apt update

Step 3: Install PHP 8.3 on Ubuntu 22.04

Now, run the following command to install PHP 8.3 on the Ubuntu system.

sudo apt install php8.3

When you run this command, it will first ask you for permission. Enter ‘Y’ to continue the installation. Once installation is completed, you can check the PHP version by running the following command.

php -v

The output should look like

PHP 8.3.3-1+ubuntu22.04.1+deb.sury.org+1 (cli) (built: Feb 15 2024 18:38:52) (NTS)
