I'm not trying to offend you, but maybe you misunderstand my question.
I can surely use _get to get access to function and variable of CI_Controller. I have known that quite before.
But my question actually is, since I have experimented before, why can I use $this->cache->redis in a model, in which $this should refer to the Model Class, not the CI_Controller?

No offense taken, but you're contradicting yourself ...

If you knew how __get() works (that's two underscores, not one), then you wouldn't be asking this question. And if you don't understand it - you didn't really follow through that first link, which explains it:

Code:

$this->cache

Is interpreted by PHP (given the current state of your class) as:

Code:

[current class instance] -> [inaccessible or non-existent property]

And gets executed as:

Code:

[current class instance] -> __get([name of the inaccessible or non-existent property])

That's what __get() is made for, you don't use it as $this->__get($something) ... that'd be silly.
