Those member projects include codebases like Zend Framework, Symfony, Composer and Doctrine. Those standards are are a very accurate representation of the way the best, most popular open source PHP code is being written.The only controversy I'm aware of is those petty pull requests opened by people who didn't like that they chose spaces over tabs, which eventually drove one of the founders of the group to quit out of frustration.
