PHP挂钩设置通过不同的类调用

Question

I'm going to structure this as best I can. Basically I have a Hook class that works by adding supplied hooks.

An example of this would be:

$this->registry->hook->add('HOOK_NAME', 'CLASS_NAME||METHOD_NAME')

The hook adding, calling, removing functions work great, now the issue resides when I set the hook in a separate method in a completely different class.

An example of this would be when a user logs in.

The path they take is User Controller -> Form Class -> Login Process Function

Now within this login process function, I'd like to set a hook to be called later to end the session. (Would be added as stated above)

The issue seems to be that it gets set but doesn't stay persistently, if that makes sense?

If anyone is interested, this is what the hook add function looks like:

function add($hook, $callback, $params = '') {
        //make sure the hook is defined
        if (!isset($this->hooks[$hook])) {
            $this->hooks[$hook] = array();
        }
        //add the callback to the hook
        $this->hooks[$hook]['callback'] = $callback;
        // add the params if supplied
        if (!empty($params)) {
            $this->hooks[$hook]['params'] = $params;
        }
    }

Should I be using magic methods __set() and __get() ?

Any help would be appreciated! :)
