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.
