I'll start with I haven't checked out v2 yet. Here's the first things that come
immediately to mind:
namespaces - sure, call somefunc(). Oops, that's already a function.
- $title - is that the page title, or the book for sale?
I can't buy the typing $this-> all the time. You type it once, then forget about
it. I have classes that I haven't changed the code for in over 2 years.
encapsulation - Am I on my development machine with v4.1.3 or 3.0.8 hosted?
- And why should I have to change my code because of it?
- Was that a :80 that WebTV added to the hostname?
inheritance - Don't see any reason to have to explain :)
- Ok fine. It's XML to a file, not browser. Write it again.
I certainly haven't tested the overhead of using PHP classes to any significant
degree. I can tell you that using OOP principles works in any language, it's just how
much that language makes it easier or not.
Sure private would be nice, but it can complicate coding. I certainly don't see
that as a reason not to use it.
My .22 cents,
John
