How to fix   Complexity   

Long Method

Small methods make your code easier to understand, in particular if combined with a good name. Besides, if your method is small, finding a good name is usually much easier.

For example, if you find yourself adding comments to a method's body, this is usually a good sign to extract the commented part to a new method, and use the comment as a starting point when coming up with a good name for this new method.

break is not strictly necessary here and could be removed.

The break statement is not necessary if it is preceded for example by a return statement:

switch ($x) {
    case 1:
        return 'foo';
        break; // This break is not necessary and can be left off.
}

If you would like to keep this construct to be consistent with other case statements, you can safely mark this issue as a false-positive.

Duplication introduced by
This method seems to be duplicated in your project.

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.

You can also find more detailed suggestions in the “Code” section of your repository.
