Coding Style introduced 2018-03-30 15:48 UTC by Report Bug Copy Issue Report It is generally advisable to only define one property per statement.

			0 ignored issues – show Unused Code introduced 2018-03-30 15:48 UTC by Report Bug Copy Issue Report `$this->disregardThrowable();` 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.
