Readable code 🔍

🎯 Objectives

To be able to make decisions about when and how to refactor less readable code.
To be able to adhere to known PHP code standards like PSR12.
To be able to think critically about code principles and not follow them blindly.

Have a look at this code and try to understand what it does.
Read the following article Jason McCreary on writing clean code
Have the code follow a consistent writing standard. For now, we'll roll with the widely used PSR12.
Rewrite the file in a way that would improve readability for you.
Don't install PHP codesniffer (yet).
When you are done, discuss your solution in groups of two.

Don't aim for perfect all the time, aim for good enough / continuous improvement.
When refactoring, focus on one section (or one thing) first (e.g. a specific function or clear naming).
Work in small steps. Write these as separate to-do's if you like. Test after every step and use small commits when you're sure everything still works.
When in doubt what approach is better, think "what would help me to understand this quickly if I see it again a year from now".
Be critical: if you think a certain tip isn't beneficial to your code, ignore or tweak it.
When getting used to a standard, don't jump to auto-rewrites immediately. Get used to write code following the standard yourself first.
