Repositories configuration:

On Fedora, standards repositories are enough, on Enterprise Linux (RHEL, CentOS) the Extra Packages for Enterprise Linux (EPEL) and Code Ready Builder (CRB) repositories must be configured.

Fedora 40

dnf install https://rpms.remirepo.net/fedora/remi-release-40.rpm

Fedora 39

dnf install https://rpms.remirepo.net/fedora/remi-release-39.rpm

RHEL version 9.4

dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
dnf install https://rpms.remirepo.net/enterprise/remi-release-9.rpm
subscription-manager repos --enable codeready-builder-for-rhel-9-x86_64-rpms

RHEL version 8.9

dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
dnf install https://rpms.remirepo.net/enterprise/remi-release-8.rpm
subscription-manager repos --enable codeready-builder-for-rhel-8-x86_64-rpms

Alma, CentOS Stream, Rocky version 9

dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
dnf install https://rpms.remirepo.net/enterprise/remi-release-9.rpm
crb install

Alma, CentOS Stream, Rocky version 8

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

 

php module usage

 

With Fedora and EL ≥ 8, you can simply use the remi-8.3 stream of the php module

dnf module reset php
dnf module install php:remi-8.3

 

PHP upgrade

 

By choice, the packages have the same name as in the distribution, so a simple update is enough:

yum update

That's all :)

$ php -v
PHP 8.3.7 (cli) (built: May  7 2024 16:35:26) (NTS gcc x86_64)
Copyright (c) The PHP Group
Zend Engine v4.3.7, Copyright (c) Zend Technologies
    with Zend OPcache v8.3.7, Copyright (c), by Zend Technologies

 

Known issues

The upgrade can fail (by design) when some installed extensions are not yet compatible with  PHP 8.3.

See the compatibility tracking list: PECL extensions RPM status

If these extensions are not mandatory, you can remove them before the upgrade, otherwise, you must be patient.

Warning: some extensions are still under development, but it seems useful to provide them to upgrade more people and allow users to give feedback to the authors.

 

More information

If you prefer to install PHP 8.3 beside the default PHP version, this can be achieved using the php83 prefixed packages, see the PHP 8.3 as Software Collection post.

You can also try the configuration wizard.

The packages available in the repository were used as sources for Fedora 40.

By providing a full feature PHP stack, with about 130 available extensions, 10 PHP versions, as base and SCL packages, for Fedora and Enterprise Linux, and with 300 000 downloads per day, the remi repository became in the last 18 years a reference for PHP users on RPM based distributions, maintained by an active contributor to the projects (Fedora, PHP, PECL...).
