Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation. You can also find more detailed suggestions in the “Code” section of your repository. Loading history...

		0 ignored issues – show Bug introduced 2018-08-24 00:23 UTC by Report Bug Copy Issue Report It seems like `$current` defined by `$context->create()` on line `37` can also be of type `object<Railt\SDL\Frontend\IR\JoinableOpcode>`; however, `Railt\SDL\Frontend\IR\Op...chOpcode::__construct()` does only seem to accept `null`, maybe add an additional type check? If a method or function can return multiple different values and unless you are sure that you only can receive a single value in this context, we recommend to add an additional type check: /** * @return array\|string */ function returnsDifferentValues($x) { if ($x) { return 'foo'; } return array(); } $x = returnsDifferentValues($y); if (is_array($x)) { // $x is an array. } If this a common case that PHP Analyzer should handle natively, please let us know by opening an issue.
