You might want to pick up a book on programming to read up on this.
In a nutshell, a function should do something specific. It's good to use
functions when you do the same thing in different places in your code so
that you don't need to copy/paste your code over and over.
function foo()
{
$x = 1;
$y = 2;
return $x + $y;
}
$bar = foo();
print $bar;

A class/object is a collection of functions and variables that are
contained within their own scope. (vague description)
class foobar
{
var $x = 10;
var $y = NULL;
function foobar($y)
{
$this->y = $y;
}
function add()
{
return $this->x + $this->y;
}
function subtract()
{
return $this->x - $this->y;
}
}
$object =& new foobar(4);
print $object->add() . "\n";
print $object->subtract() . "\n";
# set y to a new number
$object->y = 2;
print $object->add() . "\n";
print $object->subtract() . "\n";

As it sounds like you're still new to this, I would pick up a book or
read some material online that will better show you when to use either
and play around with them both.
Have fun
