阻止从URL调用函数但允许在内部调用

Question

I have a controller which have a function test(). I want to make this function inaccessible when access by the URL and I can't make private or protected because I want the same function to used by other controllers.

How can I achieve this, any suggestions?

Answer 1

If the function file is brought in by include or require functions to the controller file then you could have something like this at the start of your function file:

defined("CONTROLLER") or die();

Then, before the include function calls the function file in, use:

define("CONTROLLER", true);

That way, the function file is killed by the die() command when accessed directly but runs as normal on any page you specifically included it in.
