27. HTTP server Handle client request PHP initialisation PHP runs, index.php executed Bootstrap Framework loads all required dependencies Request The server request is parsed producing a request object Routing The request is examined and matched to a registered route Application logic The matched controller action is invoked. The business logic of the request takes place here, including loading of models and views, gathering data and rendering the result. Framework execution Friday, 25 May 12
28. // If there is no cached user if ( ! $user = Cache::instance() ->load('sian12345')) { // Load an instance of sian // user using HMVC $user = Request::factory('user/sian') ->execute(); } Friday, 25 May 12
