to function() or to include()?

[Anon]

I have the concepts down pretty well, but I'm not sure of the pros and cons between seperating code out as a function or as an included file.

Can some of you give your oppinion on this one?

Thanks,

well, for one, including a file takes up time and resources to open the file, read it, parse it, and close it back up. having to include several files as opposed to calling several functions will take much more time to execute.

Thanks Chris.

One of the advantages I saw in creating an include() file, such as a 'create new user' or 'user log-in' was that I could call that same code in other, unrelated applications and avoid having to rewrite the code.

Am I missing the mark here? Is there a way to write a function so that I can call it in other apps (without writing it in to a class)?
