I teach OOP thinking at the local college and haven't run into a
problem that doesn't fit. For example, in my last class I had a woman
who wanted to pick out a blue dress for her upcoming wedding
anniversary. The class worked out the problem with a OOP solution.

That's for certain -- but in time just about everyone can understand
the basic concepts of OOP.

I agree with that because part of OOP is understanding/defining the
problem through an object oriented perspective -- it's a paradigm
shift in thinking.

However, a programmer who is good in procedural also understands
problem solving. OOP and Procedural are just two different approaches
and each brings it's own set of tools/problems to the table.

While I teach OOP, I don't write any OOP for clients. My charge is to
do things quickly and OOP requires a considerable amount of analysis
before creating a solution. In most cases, I don't have the time.
Besides, I'm more of an agile programmer and that doesn't lend itself
well to OOP, IMO.

Also IMO, one can argue the advantages that OOP and Design Patterns
bring to the table over procedural, but after all is said and done,
if you know your stuff in procedural, OOP is not going to provide you
with much that you don't already have.

Cheers,

My viewpoint may be jaundiced from having programmed in C++, but the
polymorphism of PHP seems a little crippled by comparison.

I wholeheartedly agree, but I figured out how to work with it in PHP to
my advantage and the advantage of my team. It'll get better...

Certainly it is lacking compared to C++, but it's difficult to get that
kind of functionality from a loosely typed language.

Cheers,

You also have to consider that whilst PHP provides all the fancy
clever OOP facilities, it is written in C, not C++. So, as you say, if
you know your stuff ...
