Production environment

1 - set a variable in the config to specify production / deveploment

'application' => [
        'siteUrl'        => 'https://something.net',
        'controllersDir' => APP_PATH . '/app/controllers/',
        'modelsDir'      => APP_PATH . '/app/models/',
        'viewsDir'       => APP_PATH . '/app/views/',
        'baseUri'        => '/',
        'production'     => false,

2 - When now use this variable in the service.php to configure the controller . If its in production 404 if not, phalcon debug mode will be on on the index.php

$di->set('dispatcher', function() use ($di, $config) {

        $dispatcher = new PhDispatcher();
        $dispatcher->setDefaultNamespace('Naruhodo\Controllers');

        //in production
        if($config->application->production)
        {
             //set event for 404
            $evManager = $di->getShared('eventsManager');

            $evManager->attach(
                'dispatch:beforeException',
                function($event, $dispatcher, $exception)
                {
                    switch ($exception->getCode()) {
                        case PhDispatcher::EXCEPTION_HANDLER_NOT_FOUND:
                        case PhDispatcher::EXCEPTION_ACTION_NOT_FOUND:
                        default:
                            $dispatcher->forward(
                                array(
                                    'controller' => 'error',
                                    'action'     => 'show404'
                                )
                            );

                        return false;
                    }
                }
            );

            $dispatcher->setEventsManager($evManager);
        }

        return $dispatcher;
    },
    true
);
