What are Coding Standards in PHP

This talk will approach a theme that, for many of us, judge it unnecessary for our applications, but it has extreme importance to accelerate the code review process, focusing only on business logic. Will be shown what are Coding Standards, how to implement a tool to automate this process and promote the debate that good practices in programming can become Coding Standard rules.

1. What are Coding Standards in PHP? by Gabriel Caruso phpDay 2019
2. Who am I? • Backend Developer at Leroy Merlin • PHP enthusiastic • PHPSP member • OSS contributor • Refactor/Stickers/ELEPHANTS lover
3. What are Coding Standards?
4. Code - Organization - Writing - Visual
5. Team - Automation - Agile - Standards
6. Why should your team have a Coding Standards?
7. - Ensure patterns - Code focusing in business logic - Speed up Code Review
8. What are the differences between Coding Standards, Code Design and Code Style?
9. Coding Standards Ensure the standardization of common patterns in the code. doctrine/coding-standard
10. Code Design Is a pattern, that might affect some logics. Strict Programming
11. Code Style The design of the code.
12. PSRs and PHP-FIG
13. How to ensure these standards?
14. Code Standards tools - PHP-CS-Fixer - PHP_CodeSniffer
15. Differences PHP-CS-Fixer • Fixers • Only work fixing code • Array syntax to configure • Focus only in Coding Standards • Easy to create Fixers PHP_CodeSniffer • Linters • Can only alert without fixing • XML syntax to configure • Flexible for Code Design and Mess Detector • Harder to create Sniffs
16. Continuous Integration - A step in the CI tool to report any fail - Git hooks to avoid commits with fails
17. How this affects your Git history?
18. Git - Git blame can be overwritten - Git bisect reports false-positives - Creates unnecessary “fix cs” commits
19. How to implement a new Coding Standards in PHP?
20. Roadmap Coding Standards First step, not changing any logic Strict Programming Helps to define the strict code style PHP 7 Scalar Type Hints Review your codebase to avoid false-positives Strict types Last step, closing the circle
