To add to the below, object classes, can have their own set of functions, called
methods. These methods are specific to the function, and ALL functions within a class
treat any properties (variables) within the class as global.
So if you have a class "Car" with two properties ("Make" and "Model"), then those two
properties can be readily accessible to any method within the class. At least I think
that's how it works. I'm not all that knowledgeable on the subject :o)

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:
stock($Sym);
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
thing.
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?
