How to Install PHP 8.3 in AlmaLinux 9?

Most web applications use PHP as a script language and interpreter. By default, when you install you will get the PHP 8.0 version but we all know that with each version, PHP gets faster so we must install PHP 8.3 to get the maximum performance. In this guide, we will see how to install PHP 8.3 in AlmaLinux 9

Step 1 – Add EPEL and REMI Repository

Before installing PHP, the first step is to add EPEL and REMI repositories that contain PHP 8.3 packages. So to add EPEL and REMI repository 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 PHP default module and install the PHP 8.3 module

Next, we will reset the default PHP module and install the PHP 8.3 module so that whatever PHP module we install later on it will install the modules from the PHP 8.3 version repository only. To do so, run the following commands one by one

    # sudo dnf module reset php

    # sudo dnf module install php:remi-8.3

Output you will get as

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