Could someone please explain the difference between classes and functions
and how to use a class. I write alot of PHP, but I never understood this at
all. I use an include statement in many of my pages and include a file with
a bunch of functions. For instance, I might have a function called stock();
In the page I am using I include the file that has this function and I call
it like this:


I am wondering if I am doing it the wrong way. So I need to better
understand classes. What is one, and why would you use it?

A class is the representation of an object, such as a person, place, or
A function is a group of commands that can be called for a specific purpose.

function addNumbers()

A function can be performed on an object, but an object (the logical
extension of class) cannot be performed on a function. Does that help?
