			0 ignored issues – show Bug introduced 2016-06-22 12:47 UTC by Report Bug Copy Issue Report It seems like `$object` can also be of type `array`; however, `Rafrsr\LibArray2Object\Array2Object::parseValue()` does only seem to accept `object`, maybe add an additional type check? If a method or function can return multiple different values and unless you are sure that you only can receive a single value in this context, we recommend to add an additional type check: /** * @return array\|string */ function returnsDifferentValues($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.
