The 'use' keyword has a bunch of different meanings in PHP. It can be be used in namespaces, traits, or binding variables to anonymous functions.

In this case, your code is trying to use a trait. It looks to me like maybe those are not supposed to be traits, but namespace declarations instead. If that's the case, move them out of the class definition and to the top of your file, before executing any other code.
