Deleting all files in order to restart the project with Symfony framework. I've found just dissapointment with Silex, not because the framework, but the time implementing something too basic.
Replacing old Silex project with this new working Symfony project.
Adding WhisperAuthBundle (but actually it should be named WhisperUserBundle).
Until now the application is able to return a list of users (json or xml) in /api/users with semantic navigation standards.
