We then need to edit our view to output this variable. $this->view->current_date_and_time = date('M d, Y - H:i:s') Returning to our project, open IndexController.php in the controllers folder, and in the indexAction method, let's pass the current date and time to our view. $this->view->variable_name = "variable value" To send data to the view, we simply assign variables to the view object and give them values, like so: Access to this view object is done via the $this->view accessor. Each controller object is created, by default, to have a view object instantiate with it. It's relatively simple to pass data from a controller to its view. Step 5: Pass Data From a Controller to its View

Which is why we see the Welcome to Zend Framework page, since index.phtml contains the HTML code for this page. After the action has been executed in the controller, ZF then automatically renders the view file inside the views folder in the following format. Inside the controller file, it takes our action value and executes that method, which is indexAction. Zend Framework then takes the controller value and looks for it in the controllers folder, namely, our IndexController.php file.
Going back to our project, open the thenextsocial/application folder and you should see - you guessed it - models, views, and controllers folders. The good thing about using the ZF CLI tool is that it automatically sets up your application to make use of Zend Framework's MVC classes, which allows you to begin working on your projects more quickly. MVC in a Zend Framework-powered application The gist of it is this: models contain our business logic, views contain our HTML, and controllers keep everything in line and tell both the views and models what to do. Many developers have found this well-defined separation indispensable for keeping their code organized, especially when more than one developer is working on the same application. The end result is that your presentation code can be consolidated in one part of your application with your business logic in another and your data access code in yet another. The MVC pattern models this separation of concerns well. Most web application code falls under one of the following three categories: presentation, business logic, and data access.
So what exactly is this MVC pattern everyone keeps talking about, and why should you care? MVC is much more than just a three-letter acronym (TLA) that you can whip out anytime you want to sound smart it has become something of a standard in the design of modern web applications.

In this series of tutorials, we'll be diving into how Zend Framework works and learning how to use its different components. That being said, Zend does have a scaffolding tool and a recommended way of setting up your application structure, which we're going to discuss in this particular tutorial. The downside is that setting up the framework isn't very easy in the beginning since it's just a bunch of classes. This is a double-edged sword - for one, it makes it easier for developers to cherry-pick libraries if they only need some. Zend Framework is made up of many different libraries and classes.
