Most frameworks in PHP follow some sort of MVC structure. The theory is simple:

The user interfaces with the view, which passes information to a controller. The controller then passes that information to a model (layer), and the model passes information back to the controller. The controller effectively stands between the view and the model. (Brandon James Savage)

Not commenting your code when you are a programmer should be illegal - @RiaCorpeno

PHPdoc is intended for documenting your code. The intention is that you always add comments to your parameters and return types in docblocks that describe what they do. There is software that can read in your code and produce documentation in pdf or HTML format that describes all your classes and functions as well as what they do and how to use them. It is a system for inline documentation as the name indicates.
