As is mentioned in this new post to PHPMaster.com, the PHP standards group is officially in the voting process on two new standards (PSR-0 being the first) setting up some standard development practices for PHP applications - PSR-1 and PSR-2.

They initially started out as one proposal but the initial round of voting didn’t yield a majority in favor. Participants did however see merit in various requirements the decision was made to split it into 2 proposals - one for mandatory interoperability and one for suggested style.

The PSR-1 standard proposes some basic coding standards (like namespacing structure and class/method naming definitions) and the PSR-2 standard covers similar things, but more in-depth with more recommendations.

If you want to find out how your application stacks up against this new standard, you can try out PHP-CS-Fixer (from Fabien Potencier) to see how many things need an update.
