Overview of this book

PHP is a beginner-friendly language, but also one that is rife with complaints of bad code,;yet no clean code books are specific to PHP. Enter Clean Code in PHP. This book is a one-stop guide to learning the theory and best practices of clean code specific to real-world PHP app development environments. This PHP book is cleanly split to help you navigate through coding practices and theories to understand and adopt the nuances of the clean code paradigm. In addition to covering best practices, tooling for code quality, and PHP design patterns, this book also presents tips and techniques for working on large-scale PHP apps with a team and writing effective documentation for your PHP projects. By the end of this book, you’ll be able to write human-friendly PHP code, which will fuel your PHP career growth and set you apart from the competition.

Understanding code

Let’s first ask ourselves about the importance of code. What really is its importance for us developers in our daily lives? For that, let’s go back in time.

A bit of history

Computer programming is, in fact, a transistor through which an electric current passes or does not pass. So, we end up with a binary system, with a value of 0 if the electric current does not pass through the transistor, and 1 if the electric current does pass. If you multiply this number of transistors by several billion, you end up with today’s processors. It works very well, and our world has been governed by this system for decades. However, there is a clear limitation: it is not humanly possible to understand and create applications with only 0s and 1s. So, we had to find a new way of writing these programs so that they became humanly possible and manageable.

We then move to the first human-readable source code: the assembly language (often abbreviated ASM...
