Though it's still early to guarantee that the PSRs will be widely adopted as the de facto standard for writing serious PHP applications, it is interesting to note that a code sniffer and fixer that looks for code deviations was developed by nobody less than Fabien Potencier, the creator of the Symfony framework. (Et bien, ils ne sont pas fous, ces franšais!) In the rest of the article we shall find out what his PHP-CS-Fixer does and how can it be integrated with a CI tool like Jenkins.
He shows how to install a tool that can help you keep your source in compliance - the "fixer" (created by Fabien Potencier) to help correct the problems found in your code. He includes the command line calls you'll need to run the tool on your code and how to add the step to your build.
