BasicApplication

To create an application is to superclass the Tessera class. An extremely simple application could be built like this:

require 'tessera.php';

class BasicApp extends Tessera {
    function index() {
        echo "Deep down, deep down, dadi dadu dadu dadi dada";
    }
}

$basic = new BasicApp(array(
    '/' => 'index'
));

For the rest of this writeup, assume that this file is saved as basic.php on your domain, tesseratic.com.

The BasicApp class superclasses the Tessera class, and in its constructor it provides routes that map to methods inside the BasicApp class. In the code, the / route maps to the BasicApp::index method. When that route is matched by a request, the method is called. Its output (if any) is buffered, and so are any associated views and layouts.
