title: When to use Smarty & when MVC frameworks
body: <p>I am doing a project , which was developed in <strong>smarty</strong>.<br>
  I have never used it before , but it looks good and clean also it have some shortcuts to do the things.<br>
  But I have always used <strong>MVC frameworks</strong> (codeignter) , it also carries its own templating system.Which also use php like smarty.
  So now I am confused between <strong>when to use Smarty &amp; when MVC frameworks</strong>.</p>
