How to fix namespace not being determined in new folders project?

Question

I upgraded from phpstorm7 to phpstorm8. Now, whenever I create a new PHP class in an existing folder, the namespace is inserted correctly. Yet when I create an empty folder and create in there a new class, the namespace is empty and I would have to manually add it.

In pictures:

1. Existing folder has the namespace:
   
2. New folder in the same project lacks the namespace.

How can I tell phpstorm to always autogenerate the current namespace?

Sometimes PhpStorm doesn't correctly detect the appropriate namespace for your source directories.

You could try to fix this by going into Settings > Project: xxx > Directories, clicking the little 'P' next to your src/ directory and setting a root namespace for your project.

(you may not have as much directories listed in the right panel, depending on the complexity of your project)
