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.
