sub functions in class

[eluser]Guntars[/eluser]
Just an Idea is, In my CMS website have a plugins facility, and I want to live these separately from root code. In general everything it's fine, but some times I need some extra function. I can solve this If I use &get;_instance. and all data loads fine, but I not really like this method.

I'm not sure if you understand what I mean, but the main question is, if it's possible to get function from function with $this method.

I know this need very few times.
