PHP 8.4 is a major update and release of the PHP programming language of the 8.x series. PHP is a widely used programming language in development of websites and Web applications.

- Union Types
- Named Arguments
- Match Expressions

- Just In Time Compilation
- And much much more…
In this short article we will be performing installation of PHP 8.4 on Rocky Linux 8 | AlmaLinux 8. PHP 8.4 packages are not available in OS AppStream repositories. We’ll need to add Remi RPM repositories to our AlmaLinux / Rocky OS which contains the packages that we need to install.
