**klein.php** is a fast & flexible router for PHP

- Flexible regular expression routing (inspired by [Sinatra](http://www.sinatrarb.com/))
- A set of [boilerplate methods](#api) for rapidly building web apps
- Almost no overhead => [Benchmarks](BENCHMARKS.md)
    - Benchmark framework:

Overview
--------

[](#overview)

This repository is a fork of the original project, created to restore active maintenance and modernize the codebase. We use this library in production and have committed to keeping it up to date and compatible with current PHP versions. The primary goal of this fork is to enable and support PHP 8.3 while preserving the original project's spirit and API where possible.

Getting started
---------------

[](#getting-started)

1. PHP >= 8.3 is required
2. Install Klein using [Composer](#composer-installation) (recommended) or manually
3. Setup [URL rewriting](https://gist.github.com/874000) so that all requests are handled by **index.php**
4. (Optional) Throw in some [APC](http://pecl.php.net/package/APC) for good measure

Composer Installation
---------------------

[](#composer-installation)

1. Get [Composer](http://getcomposer.org/)
2. Require Klein with `php composer.phar require klein/klein`
3. Add the following to your application's main PHP file: `require 'vendor/autoload.php';`

Example
-------

[](#example)

*Hello World* - Obligatory hello world example

```
