Learning programming is not an easy and long process. Learning the syntax of the language is the easiest and shortest part of the journey, but you can’t start without it. This course is dedicated to the basics of writing programs in PHP.
Information can be placed in special “storages” – variables. This allows you to reuse existing data and not to duplicate it in different parts of the code. In this module, we will learn how to change variables and name them so that reading your code will be understandable for any developer.
