In the general topics section on views it gives this example:

Let’s try it with your controller file. Open it add this code:

Code:
<?php

class Blog extends CI_Controller {

       public function index()

       {

               $data['title'] = "My Real Title";

               $data['heading'] = "My Real Heading";

               $this->load->view('blogview', $data);

       }

}

Now open your view file and change the text to variables that correspond to the array keys in your data:

Code:
<html>

<head>

       <title><?php echo $title;?></title>

</head>

<body>

       <h1><?php echo $heading;?></h1>

</body>

</html>

I'm confused how the view file can access the variable $title without accessing the array that it is in. I would expect it to be something like

Code:
<html>

<head>

       <title><?php echo $data['title']; ?></title>

</head>

<body>

       <h1><?php echo $data['heading']; ?></h1>

</body>

</html>

Are all of the array elements converted into stand alone variables?
Thank you.

The array $data is extracted by the loader class (library) and each array element is accessible as individual variables inside the view.

The original array ($data) is NOT passed, so it cannot be referenced in your view code.

Scroll down to the view method definition.

If you want a better understanding, the read the PHP documentation on the extract function. That function is called when views are "loaded".
