The fhooe/router-skeleton Logo: Three containers arrows going in different directions: left, up, and right. fhooe/router-skeleton

An example application, a.k.a. skeleton for getting started with fhooe/router: the simple object-oriented router developed for PHP classes in the Media Technology and Design program at the University of Applied Sciences Upper Austria. This skeleton and the library behind it are primarily designed for educational purposes (learning the concept of routing and object-oriented principles). Use it for "public" applications at your own risk.

Creating a fhooe/router Application

Use Composer to create a new project containing the skeleton files:

composer create-project fhooe/fhooe-router-skeleton path/to/install

Composer will create a project in the specified path/to/install directory.

Basic Usage

The router invocation happens in public/index.php. This front controller file receives all the requests since the associated .htaccess file will redirect everything to it.

fhooe/router can be used in two ways:

Using a Router Object (recommended)

  1. Instantiate the Router class.

    $router = new Router();
  2. Define routes using the get() and post() methods. Supply a URI pattern to match against and a callback that is executed when the pattern and protocol match.

    $router->get("/", function() {
        // e.g., load a view
    });
  3. Set a 404 callback to load a view or trigger behavior when no route matches.

    $router->set404Callback(function() {
        // e.g., load a 404 view
    });
  4. Optional: define a base path if your application is not located in your server's document root.

    $router->setBasePath("/path/to/your/files");
  5. Run the router. This will fetch the current URI, match it against the defined routes, and execute them if a match is found.

    $router->run();

Using the Static Routing Method Router::getRoute()

  1. Invoke the static method. Provide a base path as an argument if your project is not located in your server's document root. The method returns the route as a string in the form of PROTOCOL /pattern , e.g., GET /, when a GET request was made to the root directory.

    $route = Router::getRoute("/path/to/your/files");
  2. Use a conditional expression to decide what to do with the matched route.

    switch($route) {
        case "GET /":
            // e.g., load a view
            break;
        default:
            // e.g., load the 404 view
            break;
    }

Displaying Output

Simple example view files in the form of HTML and PHP files are located in the views directory together with Twig examples for cleaner output.

Three Twig extensions have been added.

  • RouterExtension provides the functions url_for() and get_base_path() in templates for generating URLs and retrieving the base path from the Router object.
  • SessionExtension provides the function session(key) for retrieving entries in the $_SESSION superglobal.
  • DebugExtension provides the function dump() for dumping variables in templates (similar to var_dump()).

Browsing the Application

For taking a quick look, you can use the PHP built-in web server:

cd path/to/install
composer start

Navigate to http://localhost:8888/ in your browser to see the application in action.
