README

A lightweight and blazing fast router (see benchmarks) using a radix trie to store dynamic routes.

This router maps routes to user defined handlers and can do the reverse operation (reverse routing).

Installation

It's recommended that you use Composer to install Piko Router.

composer require piko/router

Usage

A basic example:

use Piko\Router;

$router = new Router();
$router->addRoute('/', 'homeView');
$router->addRoute('/user/:id', 'userView');

$match = $router->resolve('/');
echo $match->handler; // homeView

$match = $router->resolve('/user/10');
echo $match->handler; // userView
echo $match->params['id']; // 10

// Use of the $match->handler to dispatch an action
// ...

// Reverse routing
echo $router->getUrl('homeView'); // /
echo $router->getUrl('userView', ['id' => 3]); // /user/3

Dynamic handlers:

use Piko\Router;

$router = new Router();
$router->addRoute('/admin/:module/:action', ':module/admin/:action');

$match = $router->resolve('/admin/user/add');
echo $match->handler; // user/admin/add

echo $router->getUrl('blog/admin/index'); // /admin/blog/index

Advanced usage: See RouterTest.php
