How does the lithium PHP framework generate a $this context in a PHP page?
Question
I've been investigating the Lithium PHP Framework and I don't understand how it sets $this->context; ( particularly in this layout .)
Since you cannot simply re-assign $this obviously this layout will get included at some point and what confuses me even more is the fact that they use $this outside a class definition.
I haven't coded PHP in a while so please help me out here.

The first idea that strikes me is that this templating page is called from a method.
class Viewer
{
public $html;
private $title;
private $content;
public function __construct()
{
$this->html = new \Utilities\HTMLBag();
}
public function loadView($template)
{
ob_start();
include 'path/to/views/'.$template.'.php';
$this->content = ob_get_clean();
}
public function title()
{
return $this->title;
}
}
From this point, the included $template can access any method of Viewer's class

Simply: By calling include/require inside of an method in a class.
File A.php:
<?php
class A {
public $test = 'Hello';
public function xyz() {
include 'B.php';
}
}
File B.php:
<html>
<body><?php echo $this->test; ?></body>
</html>
