Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

Same issue here
there is an issue with PHP empty strings test
PHPUnit_Framework_Exception: Argument #2 (No Value) of PHPUnit_Framework_Assert::assertCount() must be a countable or traversable
What?
no need for all this,
My code only has 21 lines and I can shorten it to less than 10 lines :).

we should write a similar function to the built-in function that do the same idea.
