quimcalpe/router

, _(*1)

Regexp based Router, easy to use and with a rich feature set. It includes various built-in dispatchers, and we also provide an interface to develop fully customized dispatchers for your project., _(*2)

Install

Via Composer, _(*3)

``` bash $ composer require quimcalpe/router, <sub>(*4)</sub>

## Requirements

The following versions of PHP are supported by this version.

* PHP 8.1

## Basic Usage

```php
// Require composer autoloader
require __DIR__ . '/vendor/autoload.php';

use QuimCalpe\Router\Router;
use QuimCalpe\Router\Dispatcher\SimpleDispatcher;

// Create Router instance
$router = new Router();

// Define routes, last parameter defining route name is optional
$router->addRoute('GET', '/users', 'Quimi\Controllers\UserController', 'user_list');
$router->addRoute('GET', '/users/edit/{id:number}', 'Quimi\Controllers\UserController::edit', 'user_edit');
$router->addRoute(['POST', 'DELETE'], '/users/remove/{id:number}', 'Quimi\Controllers\UserController::remove', 'user_delete');

// Sugar methods for common verbs are also available (GET, POST, PUT, DELETE...)
$router->addGet('/user/{id}', 'Quimi\Controllers\UserController::show', 'user_show');

// You can also create a QuimCalpe\Router\Route\Route value object and add directly to router's `->add()`
$route = new Route('GET', '/', 'Quimi\Controllers\HomeController', 'home');
$router->add($route);

try {
    // Match routes
    $route = $router->parse($_SERVER['REQUEST_METHOD'], $_SERVER['REQUEST_URI']);
    // Dispatch route
    $dispatcher = new SimpleDispatcher();
    $response = $dispatcher->handle($route);
} catch (QuimCalpe\Router\Exception\MethodNotAllowedException $e) {
    header('HTTP/1.0 405 Method Not Allowed');
    // exception message contains allowed methods
    header('Allow: '.$e->getMessage());
} catch (QuimCalpe\Router\Exception\RouteNotFoundException $e) {
    header('HTTP/1.0 404 Not Found');
    // not found....
}

Constructor optional Route[] parameter

You can alternatively pass an array of Route objects to Router's constructor, and routes will be created;, <sub>(*5)</sub>

use QuimCalpe\Router\Router;
use QuimCalpe\Router\Route\Route;

$routes = [
    new Route('GET', '/users', 'Quimi\Controllers\UserController', 'user_list'),
    new Route('GET', '/users/edit/{id:number}', 'Quimi\Controllers\UserController::edit', 'user_edit'),
    new Route(['POST', 'DELETE'], '/users/remove/{id:number}', 'Quimi\Controllers\UserController::remove', 'user_delete'),
]

$router = new Router($routes);

This array can be included from another file, enabling config separation in a simple way., <sub>(*6)</sub>

Route Providers

If you want to import a bunch of Routes from a specific package/namespace/bundle and you want to keep routes organized, you can use Route providers, define your provider like this:, <sub>(*7)</sub>

namespace My\Package;

use QuimCalpe\Router\Route\Route;
use QuimCalpe\Router\Route\RouteProvider;

class MyPackageRoutes implements RouteProvider
{
    public function routes(): array
    {
        return [
            new Route('GET', '/users', 'Quimi\Controllers\UserController', 'user_list'),
            new Route('GET', '/users/edit/{id:number}', 'Quimi\Controllers\UserController::edit', 'user_edit'),
            new Route(['POST', 'DELETE'], '/users/remove/{id:number}', 'Quimi\Controllers\UserController::remove', 'user_delete'),
        ];
    }
}

And then initialize the Router with:, <sub>(*8)</sub>

$router = new Router();
$router->addRouteProvider(new \My\Package\MyPackageRoutes());

Route Patterns

Basic regexp patterns are supported, some are already included:, <sub>(*9)</sub>

• [^/]+ as default
• 'word' => \w+
• 'number' => \d+
• 'slug' => [A-Za-z0-9_-]+

Patterns can be used this way:, <sub>(*10)</sub>

$router->addRoute('GET', '/users/edit/{id:number}', 'Controller::action');
$router->addRoute('GET', '/users/{name:word}', 'Controller::action');

You can define your own patterns:, <sub>(*11)</sub>

$router->addPattern("phone", "[0-9]-[0-9]{3}-[[0-9]{3}-[0-9]{4}"); // #-###-###-####
$router->addRoute("GET", "/customer/{phone:phone}", "Vendor\Package\Controller");
$parsedRoute = $router->parse("GET", "/customer/1-222-333-4444");

Wildcards

Wildcards in routes can be used with WildcardDispatcher:, <sub>(*12)</sub>

$router->addRoute('GET', '/test/{controller}/{action}/{id}', 'Vendor\Package\{controller}::{action}');
$parsedRoute = $router->parse("GET", "/test/user/edit");
$dispatcher = new WildcardDispatcher;
$response = $dispatcher->handle($parsedRoute); // => Vendor\Package\User::edit($id)

Request Response

Standard Request - Response workflow with Symfony HttpFoundation components is supported with RequestResponseDispatcher:, <sub>(*13)</sub>

use Symfony\Component\HttpFoundation\Request;
use QuimCalpe\Router\Router;
use QuimCalpe\Router\Dispatcher\RequestResponseDispatcher;

$router = new Router();
$router->addRoute('GET', '/users', 'Quimi\Controllers\UserController::index');

$request = Request::createFromGlobals();
$route = $router->parse($request->getMethod(), $request->getPathInfo());

// You can optionally modify the request object here before dispatching:
$request->attributes->set('foo', 'bar');

$dispatcher = new RequestResponseDispatcher($request);
$response = $dispatcher->handle($route);
$response->send();

PSR-7 HTTP Message

A built-in PSR7Dispatcher is available to work with PHP-FIG's PSR-7 HTTP Message standard implementations, an example using Zend Diactoros and a simple PSR-7 Response Sender would look like this:, <sub>(*14)</sub>

use QuimCalpe\Router\Router;
use QuimCalpe\Router\Route\Route;
use QuimCalpe\Router\Dispatcher\PSR7Dispatcher;
use function QuimCalpe\ResponseSender\send AS send_response;
use Zend\Diactoros\ServerRequestFactory;
use Zend\Diactoros\Response;

$router = new Router();
$router->add(new Route("GET", "/test", "ControllerFoo"));

$request = ServerRequestFactory::fromGlobals();
$route = $router->parse($request->getMethod(), $request->getUri()->getPath());

$dispatcher = new PSR7Dispatcher($request, new Response());
$response = $dispatcher->handle($route);
send_response($response);

Custom Dispatcher

You can create your custom Dispatcher, implementing DispatcherInterface:, <sub>(*15)</sub>

interface DispatcherInterface
{
    public function handle(ParsedRoute $route): mixed;
}

QuimCalpe\Router\Route\ParsedRoute is a small Value Object with controller() and params() methods already parsed by Router::parse., <sub>(*16)</sub>

Trailing slash

Default behaviour is to honour distinction between routes with and wothout trailing slashes:, <sub>(*17)</sub>

$router = new Router();
$router->addRoute('GET', '/users', 'Controller');
$router->parse('GET', '/users'); // => OK!
$router->parse('GET', '/users/'); // => NOT FOUND

You can disable this behaviour with disableTrailingSlashCheck method:, <sub>(*18)</sub>

$router = new Router();
$router->addRoute('GET', '/users', 'Controller');
$router->disableTrailingSlashCheck();
$router->parse('GET', '/users'); // => OK!
$router->parse('GET', '/users/'); // => OK!
