		0 ignored issues – show Unused Code introduced 2016-08-07 15:33 UTC by Report Bug Copy Issue Report `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.
