The document discusses coding standards and tools for PHP code quality and formatting. It recommends using PHP Mess Detector (PHPMD) for naming conventions, size, complexity and other structural issues. PHP Code Sniffer (PHPCS) is recommended for whitespace and other easily fixable issues. The document demonstrates how to install and configure both tools, including generating ruleset files and integrating them into continuous integration to enforce code standards.

5. WHY I AM HERE TODAY

6. SO WHAT IS THIS TALK ABOUT?

7. PHP!

8. CODING GUIDELINES!

9. THE TOOLS
PHP MESSDETECTOR
Complexity, long term maintainability, keeps you honest when
designing
PHP CODE SNIFFER
Code formatting, simple coding errors, helps you stay consistent in a
team

10. PURPOSE (IMHO)
PHPMD is for naming, size, complexity and all the hard to change
things
PHPCS is for whitespace and all the things that are easy to fix

11. HOW TO MAKE USE OF THEM
Configure rules that match the way you are working!
It's easier than it feels!

12. WHAT ABOUT STANDARDS?
PHPMD: Use all the rules, they are reasonable. Configure them later
PHPCS: Use PSR2. Replace things if they don't work for your team

13. INSTALLING
{
"require": {
"squizlabs/php_codesniffer": "*",
"phpmd/phpmd": "*"
},
"config": {
"bin-dir": "/usr/local/bin/"
}
}

14. DEMO
Let's create ruleset files for both of the tools :)
http://edorian.github.io/php-coding-standard-generator/#phpmd

15. COMMANDS USED
Use most of PHPMDs rules:
Use your custom ruleset:
Use PSR2 with PHPCS:
Use your own PHPCS rules:
phpmd source text codesize,unusedcode,naming,design
phpmd source text phpmd.xml
phpcs --standard=PSR2 source/
phpcs --standard=phpcs.xml source/

16. CONTINUOUS INTEGRATION
Real world usage along a projects lifecylce
Pretty graphs in Jenkins!
Fail your travis ci build on phpcs errors?
Fail your travis ci build on phpmd errors???

17. THANK YOU!
