Here is a quick howto upgrade default PHP version provided on Fedora, RHEL, CentOS, AlmaLinux, Rocky Linux or other clones with latest version 8.4.
You can also follow the Wizard instructions.
Architectures:
The repository is available for x86_64 (Intel/AMD) and aarch64 (ARM).
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.

PHP module usage
With Fedora and EL, you can simply use the remi-8.4 stream of the php module
With Fedora 41 (dnf5 has partial module support)
dnf module reset php
dnf module enable php:remi-8.4
dnf install php-cli php-fpm php-mbstring php-xml
Other distributions (dnf4)
dnf module switch-to php:remi-8.4/common
PHP upgrade
By choice, the packages have the same name as in the distribution, so a simple update is enough:
dnf update
That's all :)
$ php -v
PHP 8.4.2 (cli) (built: Dec 17 2024 15:31:31) (NTS gcc x86_64)
Copyright (c) The PHP Group
Built by Remi's RPM repository #StandWithUkraine
Zend Engine v4.4.2, Copyright (c) Zend Technologies
with Zend OPcache v8.4.2, Copyright (c), by Zend Technologies
Known issues
The upgrade can fail (by design) when some installed extensions are not yet compatible with PHP 8.4.
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 8.4 beside the default PHP version, this can be achieved using the php84 prefixed packages, see the PHP 8.4 as Software Collection post.
You can also try the configuration wizard.
The packages available in the repository were used as sources for Fedora 42.
By providing a full feature PHP stack, with about 150 available extensions, 11 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 19 years a reference for PHP users on RPM based distributions, maintained by an active contributor to the projects (Fedora, PHP, PECL...).
