Step 1: Enable EPEL and Remi Repository on CentOS/RHEL
Right off the bat, you need to enable the EPEL repository on your system. EPEL, short for Extra Packages for Enterprise Linux, is an effort from the Fedora team that provides a set of additional packages that are not present by default on RHEL & CentOS.
Remi repository is a third-party repository that provides a wide range of PHP versions for RedHat Enterprise Linux. To install the Remi repository, run the command:
Step 2: Install PHP 8 on CentOS/RHEL
Once the installation is complete, proceed and list the available php module streams as shown:
Right at the bottom, be sure to notice the remi-8.0 php module.

Additionally, you can create a sample php file in the /var/www/html folder as shown:
Then add the following PHP code which will populate the version of PHP alongside installed modules.
Save and exit. Be sure to restart the Apache or Nginx web server as shown.
Next, head over to your browser and go to the address shown:
The webpage displays a wealth of information regarding the version of PHP installed such as build date, build system, Architecture, and a host of PHP extensions.
