Synopsis

A simple and fast router, nothing more. The tree-building mechanism is used to quickly find the route.

Code Example

$switcher = new \vivace\router\Switcher([
    //To check the URL path in a template, the rule must begin with a slash, for example /foo/bar
    '/hello/:message' => function (\Psr\Http\Message\ServerRequestInterface $request, \Psr\Http\Message\ResponseInterface $response) {
        return 'Hello ' . $request->getAttribute('message');
    },
    '/' => function (\Psr\Http\Message\ServerRequestInterface $request, \Psr\Http\Message\ResponseInterface $response) {
        return 'Index Page';
    },
    'POST/user' => function (\Psr\Http\Message\ServerRequestInterface $request, \Psr\Http\Message\ResponseInterface $response) {
        return 'Create user';
    },
    'GET//:app.mysite.com/user/:id ' => function (\Psr\Http\Message\ServerRequestInterface $request, \Psr\Http\Message\ResponseInterface $response) {
        $app = $request->getAttribute('app');
        $id = $request->getAttribute('id');
        return "Request to $app for getting user by id=$id";
    },
    //domain rules should started with double slashes `//`
    '//admin.mysite.com' => function (\Psr\Http\Message\ServerRequestInterface $request, \Psr\Http\Message\ResponseInterface $response) {
        return 'Admin page';
    },
    //It supports nested in one another
    '/api' => new \vivace\router\Switcher([
        '/v1' => function () {
            return 'Nested switcher';
        },
        '/v2' => new \vivace\router\Switcher([
            '/' => function () {
                return 'Deep nested switcher';
            }
        ])
    ]),
    'OPTIONS' => function(){
        return 'Request with OPTIONS method.';
    }
]);

//$request and $response is objects, which implementation of psr-7, this library not contain implementation psr-7, you should use third-party libraries, which do it.
$response = $switcher->switch($request, $response);
echo $response->getBody()->getContents();

Motivation

The goal was to create a fast router with support for routing over the host, capturing variables, embedding. Compatibility with PSR-7 was also required.
