include "" vs $this->load->library()

[eluser]Dave Stewart[/eluser]
Hello,

New to the ways of CI, I'm aiming to adopt best practices and attain a high belt in CI-fu!

From what I can tell from the documentation, include is now effectively redundant because any classes or functions are loaded dynamically using $this->load->class/library/helper/etc().

But are there any situations where you would use include? For example your own external functions, or should I look at converting all my classes and functions to CI Libraries and Helpers?

Would I still use includes in views (as I saw someone else do), or should I let the controller handle everything, and only have plain old vanilla HTML in the view files?

Thanks for reading,
Dave
