Us developers can be quite picky and have certain ways of working and writing code, spaces vs tabs for example! But if you're working in a team or across multiple projects it's always good to have consistency. If code is formatted all the same it's much easier to get to the gritty details of how & what the code is doing.

Getting a tool to do this automatically so you don't have to think about it is where PHP-CS-Fixer comes in. Installation is easy:

composer global require friendsofphp/php-cs-fixer

Running it for PSR-2 is simple and you can use the --dry-run flag to output any fixes before it runs and finally fixing all violations with:

php-cs-fixer fix --rules=@PSR2 --verbose --diff app

There are quite a lot of different rules you can apply so instead of appending them all to the command you can create a per project .php_cs.dist file which will then be used when running php-cs-fixer fix, an example here uses PSR-2 and the array_syntax rule which has an option:


$finder = PhpCsFixer\Finder::create()

return PhpCsFixer\Config::create()
        '@PSR2' => true,

Bitbucket Pipelines

Running the fixer automatically in a pipeline is quite straight forward, first require the package in your app as a dev dependency:

composer require friendsofphp/php-cs-fixer --dev

Then add the fix command to your pipeline scripts, note it's using the --stop-onviolation & --using-cache=no flags. A complete bitbucket-pipelines.yml file I've got on a project looks like this to check for fixes and finally run the test suite.
