PHP is a widely used scripting language along with an interpreter. We all know that the latest version of PHP is always faster and better than its previous version. When you install PHP on your Rocky Linux server, you will get PHP 8.0 version but, the latest stable version is PHP 8.3. That is better in terms of performance than PHP 8.0. In this guide let’s see how to install PHP 8.3 in Rocky Linux 9.

Step 1 – Adding EPEL and REMI repository

Before proceeding with PHP 8.3 installation we will add EPEL and REMI repositories. To add these repositories, execute the following commands one by one

    # sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

    # sudo dnf -y install https://rpms.remirepo.net/enterprise/remi-release-9.2.rpm

Step 2 – Reset the old PHP Module and Install PHP 8.3

Next, let’s reset the default PHP version and install PHP 8.3 module by executing the commands below

    # sudo dnf module reset php

    # sudo dnf module install php:remi-8.3

The output should look like this

[root@linux ~]# dnf module install php:remi-8.3
