			0 ignored issues – show Bug introduced 2016-02-12 10:17 UTC by Report Bug Copy Issue Report It seems like `$outputParser` defined by `\Alchemy\Zippy\Parser\Pa...eate(static::getName())` on line `163` can also be of type `null`; however, `Alchemy\Zippy\Adapter\Ab...yAdapter::__construct()` does only seem to accept `object<Alchemy\Zippy\Parser\ParserInterface>`, maybe add an additional type check? If a method or function can return multiple different values and unless you are sure that you only can receive a single value in this context, we recommend to add an additional type check: /** * @return array\|string */ function returnsDifferentValues($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.
