PHP is an open-source programming language that is embedded in HTML. It is mainly used for creating dynamic web sites such as blogs, e-commerce sites, etc. Rasmus Lerdorf created it in 1994.
CentOS 8 / RHEL 8 comes with PHP v7.2 by default.
In this post, we will see how to install PHP 8.0 on CentOS 8 / RHEL 8.
Add Remi Repository
Remi, a third-party repository that offers multiple PHP versions (8.0 / 7.4 / 7.3 / 7.2) for Red Hat Enterprise Linux.
Remi repository requires EPEL repository be enabled on the system. So, install the latest EPEL repository auto-configuration rpm on the system to enable the EPEL repository.
dnf install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
Then, install the Remi repository auto-configuration package using the below command.
dnf install -y https://rpms.remirepo.net/enterprise/remi-release-8.rpm
Output:

Once you install the Remi repository rpm, list the available PHP module streams.
dnf module list php
You should see the below output.
CentOS-8 - AppStream Name Stream Profiles Summary php 7.2 [d] common [d], devel, minimal PHP scripting language php 7.3 common [d], devel, minimal PHP scripting language Remi's Modular repository for Enterprise Linux 8 - x86_64 Name Stream Profiles Summary php remi-7.2 common [d], devel, minimal PHP scripting language php remi-7.3 common [d], devel, minimal PHP scripting language php remi-7.4 common [d], devel, minimal PHP scripting language php remi-8.0 common [d], devel, minimal PHP scripting language Hint: [d]efault, [e]nabled, [x]disabled, [i]nstalled
Install PHP 8.0 on CentOS 8 / RHEL 8
Enable php:remi-8.0 module to install PHP 8.0.
dnf module enable php:remi-8.0 -y
Output:
Dependencies resolved. =================================================================================================================== Package Arch Version Repository Size =================================================================================================================== Enabling module streams: php remi-8.0 Transaction Summary =================================================================================================================== Complete! Switching module streams does not alter installed packages (see 'module enable' in dnf(8) for details)
Install PHP 8.0 on CentOS 8 / RHEL 8 with the dnf command.
dnf install -y php php-cli php-common
Install PHP 7.x on CentOS 8 / RHEL 8
Enable php:remi-7.x module to install PHP 7.x on the system as shown in this article.
Install PHP-FPM
If you are setting up the LEMP stack on RHEL 8, you might want to install php-fpm.
dnf install -y php-fpm
Install PHP Extensions
PHP extensions are compiled libraries that enable specific support for your code.
To have MySQL support on your code, you can install the php-mysqlnd package.
dnf install -y php-mysqlnd
The below command would now list the installed MySQL extension.
php -m | grep -i mysql
Output:
mysqli
mysqlnd
pdo_mysql
