It seems like $value can also be of type object; however, Graviton\DocumentBundle\...:arrayFilterRecursive() does only seem to accept array, maybe add an additional type check?
If a method or function can return multiple different values and unless you are
sure that you only can receive a single value in this context, we recommend
to add an additional type check:
/** * @return array|string */functionreturnsDifferentValues($x){if($x){return'foo';}returnarray();}$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.
