phalcon Routing and dispatching Dynamically set module routes

Example

$router = new \Phalcon\Mvc\Router(false);
$router->removeExtraSlashes(true);
$request = new \Phalcon\Http\Request();
$action = strtolower($request->getMethod()); // get, post, etc.
$modules = ['calendar', 'main', 'user']; // names of the modules you create

// you can define other static routes here

foreach ($modules as $module) {
    // must match what you register with the Loader service
    $namespace = 'App\\' . ucfirst($module) . '\Controllers'; 
    
    // make a group to avoid setting namespace and module for every route definition
    $moduleGroup = new \Phalcon\Mvc\Router\Group([
        'namespace' => $namespace,
        'module' => $module
    ]);
    
    // this will match a route like /calendar/index/save
    $moduleGroup->add("/{$module}/:controller/:action", [
        'controller' => 1,
        'action' => 2
    ]);
    
    // setting a prefix will apply it to all routes below
    $moduleGroup->setPrefix('/api');
    
    // this will match a route like /api/calendar/index/save
    $moduleGroup->add("/{$module}/([a-zA-Z_]+)/:action", [
        'controller' => 1,
        'action' => 2
    ]);

    // this will match a route like /api/calendar/123
    $moduleGroup->add("/{$module}/:int", [
        'moduleId' => 1,
        'controller' => 'index',
        'action' => $action // defined at the top of example
    ]);

    $router->mount($moduleGroup);
}

// you can define other static routes here

return $router;
