Ah, well Chapter 6, page 144-145 have helped clear-up a little bit of my
confusion:
"
...<snip>...
Here's a simple class definition of the Person class that shows the
$this variable in action:
class Person {
var $name;
function get_name() {
return $this->name;
}
function set_name($new_name) {
$this->name = $new_name;
}
}
As you can see, the get_name() and set_name() methods use $this to
access and set the $name property of the current object.

Declaring Properties
In the previous definition of the Person class, we explicityly declared
the $name property. Property declaration are optional and are simply a
courtesy to whoever maintains your program. It's good PHP style to
declare your properties, but you can add new properties at any time.
...<snip>...
You can assign default values to properties, but those default values
must be simple constants:
var $name = 'J Doe'; // Works
var $age = 0; // Works
var $day = 60*60*60; // Doesn't work.
...<snip>...
"
So, I think I was getting a bit confused with the var variables... But
now it looks like it is not bad practice to get and set object
"properties", and it almost sounds like it is good practice (though, not
required) to declare these properties (var variables) for other
eyeballs/programmers.
Man, I love programming in PHP. I just wish I were better at it! :D
K, gonna go practice some on these new techniques.
Cheers,
Micky
