As a simple example, let us say your controller has a list of book data that it wants to have rendered by a view. The controller script might look something like this:
// use a model to get the data for book authors and titles.
$data = array(
'author' => 'Hernando de Soto',
'title' => 'The Mystery of Capitalism'
'author' => 'Henry Hazlitt',
'title' => 'Economics in One Lesson'
'author' => 'Milton Friedman',
'title' => 'Free to Choose'
// now assign the book data to a Zend_View instance
$view = new Zend_View();
$view->books = $data;
// and render a view script called "booklist.php"
