by the way i loop my route collection array and build Micro/Collection

    //set routes collection
    public function setRoutes($req) {

        $reqUri = $req;

        $getreqPrefix = explode('/', $reqUri);

        $collections = array();

        $collectionFiles = scandir($this->appDir . '/resources/routes');

        foreach($collectionFiles as $collectionFile){
            $pathinfo = pathinfo($collectionFile);

            if($pathinfo['extension'] === 'php'){

                $getcollection = include($this->appDir.'/resources/routes/'.$collectionFile);
                $prefixrplc =  str_replace('/', '',$getcollection['prefix']);

                if($prefixrplc == $getreqPrefix[1]){
                    $collections[] = $this->buildcollection($getcollection);
                }

            }
        }

        foreach($collections as $collection){
            $this->mount($collection);
        }

    }
    //end of setRoutes

    //build route collection
    private function buildcollection($route){

        $cltn = new Collection();

        $cltn->setPrefix($route['prefix'])
        ->setHandler($route['handler'])
        ->setLazy($route['lazy']);

        foreach($route['collection'] as $obj){

            if($obj['authentication']===false){

                $method = strtolower($obj['method']);

                if (!isset($this->_routeAllowed[$method])) {
                    $this->_routeAllowed[$method] = array();
                }
                $this->_routeAllowed[$method][] = $route['prefix'].$obj['route'];

            }

            $cltn->{$obj['method']}($obj['route'], $obj['function']);

        }

        return $cltn;

    }
    //end of buildcollection
