Karen is a simple PSR-7 micro framework with PHP7. This framework provide these names of blocks and simple Controller class:

• container
• middleware
• routes
• response
• run

You have only to write a code in your way with PSR-7 objects.

Karen uses blow components by default:

• PSR-7 Request, Response
  • zendframework/zend-diactoros
• middleware
  • relay/relay
• container
  • pimple/pimple
• aura/router
• twig/twig

• PHP 7.0 or later.

php -r "eval('?>'.file_get_contents('https://getcomposer.org/installer'));"
php composer.phar create-project brtriver/karen ./your_app

cd your_app
make server

and open http://localhost:8888/hello/karen_girls in your browser.

see web/index.php.

You have to write your logic of a controller with anonymous function:

$map->get('hello', '/hello/{name}', function($args, $controller) {
    $name = $args['name']?? 'karen';
    return $controller->render('Hello, ' . $name);
})->tokens(['name' => '.*']);

$args is arguments from routing path, and $controller is a instance of Karen\Controller class.

Karen\Controller has a render method. this is equal to $controller->response->getBody()->write($output).

For example, you want to render as simple plain:

$c['controller'] = function($c) {
	return new Controller($c['request'], $['response']);
};

And if you want to use a template engine like Twig, you have only to write with anonymous class and trait:

$c['controller'] = function($c) {
    $controller = new class($c['request'], $c['response']) extends Controller{
            use Templatable;
        };
    $controller->setTemplate($c['template']);

    return $controller;
};
