Can someone please explain to me when is a class useful over a set of
functions?
Almost always. Object oriented programming offers many many advantages
(that I cannot get into depth on here). There are a few exceptions
where you would not use classes, such as utility functions like max()
and mi
Thank you for your 2 cents I am just learning and appreciate your comments.

There is no simple answer here. I have started using classes where I find
I am writing a lot of related functions that share similar
parameters. Database connection and queries are a good
example. Authentication is another.
I have another class that builds forms, because I just hate the tedium o

Well, that's a 1 billion $$ question. I don't think one can fully grasp
that difference by reading an email. I strongly suggest you to buy

I am just wondering if I should make classes instead of functions? What
would be the benefit of that? Do you know?

You should keep classes and functions seperate in your thought process, they
are not the same and not meant to do or be the same thin

It helps a little bit, thank you. Could you provide some code as to what a
