Lesson 26 - TypeHinting and documentation in PHP

PHP OOP TypeHinting and documentation in PHP

In the "previous tutorial, Namespaces in PHP, we learned how to use namespaces and how to use them to split bigger projects into modules. Today marks the end of our object-oriented course. We're going to show you all about TypeHinting, and show you how to document code properly.
