PHP is one of the most used server-side programming languages. Many popular CMS and frameworks such as WordPress, Laravel, and many more are built in PHP.

PHP 8.0 is not available in the default CentOS repositories, If you want to install PHP 8 enable the Remi and EPEL repository by running the following command as root or user with sudo privileges :

sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf install https://rpms.remirepo.net/enterprise/remi-release-8.rpm
sudo dnf install yum-utils

Once done, reset the module and enable PHP 8:

sudo dnf module reset php
sudo dnf module install php:remi-8.0

Then, install PHP and some of the most common PHP modules:

sudo dnf install php
sudo dnf install php-{cli,fpm,mysqlnd,zip,devel,gd,mbstring,curl,xml,pear,bcmath,json}

To install any additional PHP package use command syntax:
