@v.m.p you might find the back and forth on the object operator ‘->’ interesting, especially given your question about $this, here is the discussion on Robert Gonzalez’s website:

http://www.robert-gonzalez.com/2009/03/04/php-operators-double-and-single-arrow/

I loved it that rasmus even chimed in at one point.

The $this operator is a ‘special variable’ used to “refer to the currently instantiated object.” ‘$this->name’ where name is a variable defined in the class template that creates the object.

What I find particularly special about $this-> is without it, how would an ‘object’ refer to itself?

Well, I’m not sure, but $this in OOP always refers to the current object. So in a Model definition it refers to the current instance of that Model. In a Controller definition, it refers to the current instance of that Controller. In a View definition, it refers to the current instance of that View.

maybe i’ve overlooked it…so forgive me…but did you ever get around to covering: “…and what in the world $this means at any particular point!”??

Thanks!

Yes it does make more sense now. Thank you!

Good question. To clarify, Controllers do actions in terms of responses to users: click a link, do this; submit a form, do that; etc. So Controller actions are in a broader sense. Models are the data, and something like a calculation based upon part of a Model is therefore tied to the Model, not to a Controller or a View. By doing it this way, the same information could be used in lots of Views. And again, think of Controllers as controlling user actions. Does that make more sense?

I am confused that you state “but the actual calculation should take place in the Model, not the View (or the Controller).”

I thought the controller does the actual thinking and calculations?
