PHP Design Pattern are sample solutions for structuring PHP Code.
They tell us when to use them and how participating actors (objects, functions, files, folders) playing together leads to solution.
Example MVC Pattern:
according to wikipedia article:
when to use: ... for GUI's
how to get the solution: separating application in components
in descriptions: how the actors playing together
We create three files: index.php, model.php, view.php
throughout adressbar in browser we decide (controll)
to make an addition if "index.php?add" is given
or a substraction without add "index.php"
It's a simple MVC Controller because it controlls from Navigation-Bar (User)
which model and view to choose. View shows data from Model and Model
stores data and delivers data to View
