How to fix   Duplicated Code   

Duplicated Code

Duplicated code is one of the most pungent code smells. If you need to duplicate
the same code in three or more different places, we strongly encourage you to
look into extracting the code into a single class or operation.

It seems like choice() must be provided by classes using this trait. How about adding it as abstract method to this trait?
                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
This check looks for methods that are used by a trait but not required by it.


To illustrate, let’s look at the following code example


trait Idable {
    public function equalIds(Idable $other) {
        return $this->getId() === $other->getId();
    }
}





The trait Idable provides a method equalsId that in turn relies on the
method getId(). If this method does not exist on a class mixing in this
trait, the method will fail.


Adding the getId() as an abstract method to the trait will make sure it
is available.
