Code Inspection: 'switch' with common parts

Reports the 'switch' statements with duplicated common parts.

In the following example, all branches of the switch statement contain the common echo $message statement. After the quick-fix is applied, this statement extracted from the switch statement.

                switch ($a) {
                    case 1:
                        echo $message;
                        doSmth();
                        break;
                    case 2:
                        echo $message;
                        echo $error;
                        break;
                    default:
                        echo $message;
                        doSmthElse();
                        break;
                }
            

                echo $message;
                switch ($a) {
                    case 1:
                        doSmth();
                        break;
                    case 2:
                        echo $error;
                        break;
                    default:
                        doSmthElse();
                        break;
                }
