The main difference between install php8.x and install php8.x-fpm is the type of PHP installation and how it will be used in your web environment:
php8.x (CLI version)
This command installs the PHP CLI (Command Line Interface), the main usage is for running PHP scripts from the command line (e.g., running Artisan commands in Laravel or running PHP scripts in cron jobs). CLI is not directly used to serve web requests.
sudo apt-get install php8.x
php8.x-fpm (PHP-FPM version)
This command installs PHP-FPM (FastCGI Process Manager) for PHP v8.x
PHP-FPM is a PHP handler that processes requests in a web server environment like Nginx or Apache. It is designed to handle high loads request and is more efficient than the traditional CGI approach.
If you are serving your Laravel or other applications on a web server (such as Nginx or Apache), you need PHP-FPM to process the PHP requests. This is the method most commonly used in production environments.
Example:
sudo apt-get install php8.x-fpm
Key Differences
php8.x: Installs PHP for general-purpose use (mostly command-line and script execution).
php8.x-fpm: Installs PHP with FPM, which is specifically used for serving PHP applications via a web server (e.g., Nginx or Apache).
For example, on a typical Laravel server setup, you'd install both PHP-FPM and CLI to ensure your web server can handle requests and you can execute Laravel commands via CLI.
