如何写出来的东西才叫mvc哦。小弟我艹艹艹艹熬

switch($action){
     case "add1":
        $smarty=new Smarty();
        $smarty->display("tianjiabumen.tpl");
         break;
     case "del":
          $id=$_GET['id'];
         $bm=new bumenmodel();
         $bm->id=$id;
         $bm->delete();
         header("location:bumenkongzhiqi.php?action=chaxun");
            break;

class factory(){
function __contruct(){
$this->models = array();
}
function & getModel($modelName) {
if(!isset($this->models[$modelName])){
require("{MODEL_BASEPATH}/{$modelName}");
$this->models[$modelName] = new $modelName();
}
return $this->model[$modelName];
}
}
