Kohana 全局变量被清除了吗？

我之前写了一个问题，试图绕过在 Kohana 中使用控制器，但我放弃并重写了该文件。现在，我在 Kohana 控制器中有这个 php 脚本。控制器正在呈现的视图“需要”一个 php 文件，以便我可以执行一些第三方功能。我遇到了一个重大问题并开始调试。问题似乎是包含文件内的函数无法从同一文件内访问函数外部的变量。看来 Kohana 正在以某种方式清除全局？？？

例如：

//controller.php
require_once("ccfunctions.php");

//ccfunctions.php
$test = 'something';
function test(){
  global $test;
  echo $test;
}
test();
//This does not produce anything

对此有什么想法吗？

编辑：实际上，即使在我正在渲染的视图文件中，上面的示例也不起作用。忘记包含的文件。我意识到 Kohana 试图强制执行 MVC 模型，但这很荒谬。为什么我不能创建函数并从视图文件中调用全局变量？

I wrote a question earlier trying to get around using a controller in Kohana, but I gave in and rewrote the file. So now, the I have this php script inside a Kohana controller. The view that the controller is rendering is 'requiring' a php file so I can perform some third-party functions. I was having a major issues with it and got to debugging. The problem seems that functions inside the included file cannot access variables outside the function from within that same file. It seems that Kohana is clearing the globals somehow???

example:

//controller.php
require_once("ccfunctions.php");

//ccfunctions.php
$test = 'something';
function test(){
  global $test;
  echo $test;
}
test();
//This does not produce anything

Any thoughts on this one?

EDIT:
Actually, the above example doesn't work even from my view file that is being rendered. Forget the included file. I realize Kohana tries to enforce the MVC model, but this is ridiculous. Why cannot I not create a function and call a global variable from within my view file?

在这两种情况下，您都需要为变量指定 global ：

//controller.php
require_once("ccfunctions.php");

//ccfunctions.php
global $test;
$test = 'something';
function test(){
  global $test;
  echo $test;
}
test();
//This does not produce anything

顺便说一句，这确实是很奇怪的做法，我相信在不使用 global 的情况下，任何情况都有解决方法

You need to specify global for variable in both cases:

//controller.php
require_once("ccfunctions.php");

//ccfunctions.php
global $test;
$test = 'something';
function test(){
  global $test;
  echo $test;
}
test();
//This does not produce anything

Btw, it is really weird practice and I believe there are workarounds for any case without using global
