Class controllers

You may now use a controller class instance as a callback for your Slim app routes.

$app->get('/hello/:name', '\Greeting:sayHello');

In this example, when the app receives a request for "/hello/Josh", it will instantiate class \Greeting and pass the value "Josh" into its sayHello method.

Note that we separate the class name and the class method with a single ":" colon. This is a unique syntax used by Slim to implement this functionality. Do not confuse this with the "::" syntax used for static method calls.

Request parameter defaults

When fetching request data with the \Slim\Http\Request object's get(), post(), put(), patch(), or delete() methods, you can define the default value you want if the requested data is not available. For example:

$app->get('/books', function () use ($app) {
    $value = $app->request->get('genre', 'fiction');
});

In this example, we expect the HTTP request to have a URL query parameter genre. If this query parameter does not exist, we will use "fiction" as the default value.

View Template Data

You may now pass data into a view template with \Slim\View::display() and \Slim\View::fetch().

// Fetch a rendered template into a variable
$renderedTemplate = $app->view->fetch('my-template.php', ['foo' => 'bar']);

// Echo a rendered template to the output buffer
$app->view->display('my-template.php', ['foo' => 'bar']);

Other Changes
