The PHP Object Model
PHP's object model has a number of quirks that one should be aware
of: a lack of private/protected variables or methods, no multiple
inheritance, no interfaces, etc. I call them quirks because while
the object model isn't a match for Java, PHP isn't Java - and
that's a strength, as well as a perceived weakness.
The things you can do with PHP - easy string manipulation,
variable variables, variable functions, variable classes, variable
method names, to name just a relevant few - are both the reasons
you should be using PHP, and the things that can make the object
model, "impure" as it is, wonderfully elegant to work with.
Actually using PHP's OO features is beyond the scope - and to some
extent, the point - of this presentation, but if you're unfamiliar
with it, you'll probably pick up most of it through examples by
the time we're done.
