What is Flight?

Flight is a fast, simple, extensible framework for PHP. Flight enables you to quickly and easily build RESTful web applications.

Basic Usage

// if installed with composer
require 'vendor/autoload.php';
// or if installed manually by zip file
// require 'flight/Flight.php';

Flight::route('/', function () {
  echo 'hello world!';
});

Flight::start();

Skeleton App

You can also install a skeleton app. Go to flightphp/skeleton for instructions on how to get started!

Documentation

We have our own documentation website that is built with Flight (naturally). Learn more about the framework at docs.flightphp.com.

Upgrading From v2

If you have a current project on v2, you should be able to upgrade to v2 with no issues depending on how your project was built. If there are any issues with upgrade, they are documented in the migrating to v3 documentation page. It is the intention of Flight to maintain longterm stability of the project and to not add rewrites with major version changes.

Requirements

Important

Flight requires PHP 7.4 or greater.

Note: PHP 7.4 is supported because at the current time of writing (2024) PHP 7.4 is the default version for some LTS Linux distributions. Forcing a move to PHP >8 would cause a lot of heartburn for those users.

The framework also supports PHP >8.
