Check your code follows PSR-2 and check it's got a good design on the command line

Need to check your code follows PSR-2, but it's not supported in your editor of choice? Here's a quick bit of code to check. It uses PHPCS.

$ composer require --dev "squizlabs/php_codesniffer=*"
$ vendor/bin/phpcs --standard=PSR2 your-code-path/
vendor/bin/phpcs --standard=PSR2 app/

You only need to run the composer require once.

As you can see you'll get a nice summary as to your compliance with PSR-2, and what you need to fix.

What's more you can also use this code to fix most of the style violations too!

If you want to run some fancy analytics on your code to see if your design is looking okay, use PHPMD.

$ composer require --dev "phpmd/phpmd=@stable"
$ vendor/bin/phpmd your-code/ text cleancode,codesize,design,naming,unusedcode
/home/vagrant/Code/search/php-app/app/Http/Controllers/SearchController.php:29  The class SearchController has a coupling between objects value of 13. Consider to reduce the number of dependencies under 13.

This will check against a whole bunch of rules from naming guidelines to, cyclomatic complexity, to checking for unused code. Check the PHPMD website for more details.

This will help you write lots of lovely clean code.
