PHP is a popular scripting language for web development originally created by Rasmus Lerdorf, a Danish-Canadian programmer in 1994. PHP scripts created can be executed on Linux, macOS, Windows and many other Unix systems provided PHP has been installed.

In this article we will explain the installation of PHP 8.0 on Ubuntu 20.04|Ubuntu 18.04 Linux system. In our previous guide we captured the installation of PHP 8.0 on CentOS 8/7. There are many other guides available in our website on how to install and use other versions of PHP on Ubuntu Linux machine.

The official release of PHP 8 will be on November 26, 2020. It is a new major version with many new features and performance improvements. You should also expect new breaking changes which means some modifications in your code may be needed to get it running on PHP 8. Some of the nice set of new features coming with PHP 8 are the JIT compiler, named arguments, union types, attributes, and many more.

Step 1: System Update

Update all system packages to the latest by running the commands below.

sudo apt update
sudo apt -y upgrade

A reboot is important after any upgrade.

sudo systemctl reboot

Step 2: Add Ondřej Surý PPA repository

The latest PHP packages are available in the Ondřej Surý PPA repository. Run the commands shared below to add this repository to your Ubuntu system.

sudo apt update
sudo apt install lsb-release ca-certificates apt-transport-https software-properties-common -y
sudo add-apt-repository ppa:ondrej/php

Hit enter key when prompted to add the repository:

Debian oldstable and stable packages are provided as well:

You can get more information about the packages at

IMPORTANT: The <foo>-backports is now required on older Ubuntu releases.

BUGS&FEATURES: This PPA now has a issue tracker:

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
