it's not just that, it's also a different way of thinking about your

in procedural code you would store the properties of the user in an
array or whatever, and have an include file with functions to manipulate
the user. so why not group those two together in a class?
<very simplifying example>
procedural code:
include('user_functions.php');
$user = load_user_data($userid);
$user = set_user_name($user, 'tedd');
oop code:
include('user.class.php');
$user = new User($userid);
$user->setName('tedd');
</very simplifying example>
see, same number of lines, so no added complexity. however the second
one has some advantages:
- you don't have to pass around the data since it is grouped together
with the method you call
- you don't have to worry about some ignorant developer calling
set_user_name with, say, a product array - User->setName will always be
called on a user object
- the second one looks soo better ;) (ok, you said, new paint :) )
I can understand your oop code very well -- but
your procedural code example is lacking.
First, if I were to have information tied to a
user, then I would use MySQL and establish a
record with all the fields I needed for that
user. My code simply would be:
include('user_functions.php');
$user = set_user_name($user, 'tedd');
And thus, two lines instead of three.
But in fairness, the user_functions.php would
establish a connection to the database and the
function "set_user_name($user, 'tedd')" would
simply use 'tedd' with respect to whatever
"$user" is.
The number of lines of code really doesn't apply
with respect to organization value -- after all,
the best organization is to document your code
which certainly adds lines of "code". Sure, one
can argue that remarks are not code, but code
without them would be different, so in my mind
it's all code.
I don't think that you can show me an oop example
that I can't duplicate procedurally and that's my
point. Oop provides a different organization
method.
