			0 ignored issues – show Unused Code introduced 2018-08-28 00:18 UTC by Report Bug Copy Issue Report This `foreach` statement is empty and can be removed. This check looks for `foreach` loops that have no statements or where all statements have been commented out. This may be the result of changes for debugging or the code may simply be obsolete. Consider removing the loop. Loading history...

			0 ignored issues – show Unused Code Comprehensibility introduced 2018-08-28 00:18 UTC by Report Bug Copy Issue Report `84%` of this comment could be valid code. Did you maybe forget this after debugging? Sometimes obsolete code just ends up commented out instead of removed. In this case it is better to remove the code once you have checked you do not need it. The code might also have been commented out for debugging purposes. In this case it is vital that someone uncomments it again or your project may behave in very unexpected ways in production. This check looks for comments that seem to be mostly valid code and reports them. Loading history...

			0 ignored issues – show Unused Code introduced 2018-08-28 00:18 UTC by Report Bug Copy Issue Report `if ($result instanceof \...{ return $result; }` does not seem to be reachable. This check looks for unreachable code. It uses sophisticated control flow analysis techniques to find statements which will never be executed. Unreachable code is most often the result of `return`, `die` or `exit` statements that have been added for debug purposes. function fx() { try { doSomething(); return true; } catch (\Exception $e) { return false; } return false; } In the above example, the last `return false` will never be executed, because a return statement has already been met in every possible execution path.
