Then how do you account for the fact that the only reason I added that
featue into my framework is because someone actually asked for it?

Yes, but my method will allow the customer to change the rules on a screen
instead of asking me to change some code.

You are missing the point AGAIN! Using your method you actually have to
write a line of code for each field that needs to be validated. With my
method you don't have to write any code at all as the framework
automatically calls the validation object to validate eveything in the input
array at a single stroke.

Different groups of developers have different sets of arbitrary "rules" or
"standards" which exist on top of basic programming principles. There is no
single set of rules which is universally adopted by *ALL* programmers. The
"rules" that I follow are not necessarily the same rules that you follow,
but so what? Who says that *YOUR* rules are he only rules that are allowed
to exist?

As for my understanding of the principles of OO programming, I simply stick
to the basic principles of encapsulation, inheritance and polymorphism as
documented in http://www.tonymarston.net/php-mysql/what-is-oop.html Anything
other than the basic principles is an optional extra, is totally
superfluous, and can safely be ignored.

I can't learn from you for the simple reason that you can't teach me
anything of value.

The definition of encapsulation is "The act of placing data and the
operations that perform on that data in the same class. The class then
becomes the 'capsule' or container for the data and operations." There is
nowhere in that definition which says anything about hiding the data by
setting access to "private", or even setting operations to "private".

Access is controlled by changing a property from "public" to "private". If
it is "public" then it can be accessed directly without using a getter or a
setter. If it is "private" then it cannot be accessed directly and therefore
can *ONLY* be accessed using a getter or a setter.

Therefore the use of getters and setters is directly related to the hiding
of data by changing its access from "public" to "private".

Encapsulation does *NOT* mean information hiding, therefore I do *NOT* have
to make all my properties private, therefore I do *NOT* have to use geters
and setters.

There is *NO* universal agreement on what OO is and is not. Take a look at
http://c2.com/cgi/wiki?NobodyAgreesOnWhatOoIs if you don't believe me.

Oh I see! Only those books or articles which support your twisted view are
the ones worth considering! How arrogant you are!

There are thousands of books and articles which have been written about
programming in general and OO programming in particular, yet there is no
single set of "rules" which have been accepted by everyone. It is impossible
to follow every set of rules that has ever been published, so I choose to
follow only those rules which seem sensible to me.

> Which of those are your articles, BTW?

None. They were written by others who are also not impressed with some of
the rubbish ideas that have somehow been turned into "rules".

There are plenty of "experts" out there who agree on different sets of
rules. There is no single set of rules which is universally followed by
*all* experts.

I just happen to follow a different set of rules which are favoured by a
different set of experts.

Of course you are so arrogant you will no doubt say that the experts that I
follow are wrong while the experts that you follow are the only experts
worth listening to.
