锂PHP框架如何在PHP页面中生成$ this上下文？
[英]How does the lithium PHP framework generate a $this context in a PHP page?
问题描述
I've been investigating the Lithium PHP Framework and I don't understand how it sets $this->context; 
我一直在研究Lithium PHP Framework ，我不明白它是如何设置$this->context; ( particularly in this layout .) （ 特别是在这种布局中 。）
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 $this outside a class definition. 既然你不能简单地重新分配$this这个布局会在某些时候被包含在内，更令我困惑的是他们在类定义之外使用$this 。
I haven't coded PHP in a while so please help me out here. 我有一段时间没有编写PHP，所以请在这里帮助我。

The first idea that strikes me is that this templating page is called from a method. 让我印象深刻的第一个想法是，从一个方法调用这个模板页面。
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 $template can access any method of Viewer's class 从这一点来说，包含的$template可以访问Viewer类的任何方法

Simply: By calling include/require inside of an method in a class. 简单地说：通过调用类中的方法中的include / require。
File A.php: 文件A.php：
<?php
class A {
public $test = 'Hello';
public function xyz() {
include 'B.php';
}
}
File B.php: 文件B.php：
<html>
<body><?php echo $this->test; ?></body>
</html>
