title: how to create model in symfony 3?
body: <p>I'm new in symfony. I came from codeigniter. I'm trying to study symfony but I'm confuse about using the model. Unlike codeigniter, there is a model folder added when I download it. How can add model in symfony? I try to search it to google and I found this <a href="http://symfony.com/legacy/doc/book/1_0/en/08-Inside-the-Model-Layer" rel="nofollow noreferrer">link</a>. I don't know if this is the right one.</p>
