How to clean your PHP code

This course refers to the software engineer's principles from Robert C. Martin's Clean Code book and applies to PHP. This is not a style guide. This is a guide to developing readable, reusable, and reconfigurable PHP software. Not all of the principles here must be followed, and few are even universally accepted. Although these are just guidelines, they are all summarized by the Clean Code authors over the years.

Notes

Although many developers are still using PHP5, the running environment of most of the examples in this article requires PHP 7.1.
