			0 ignored issues – show Documentation Bug introduced 2017-07-04 09:10 UTC by Report Bug Copy Issue Report It seems like `$values` can be `null`. However, the property `$values` is declared as `array`. Maybe change the type of the property to `array\|null` or add a type check? Our type inference engine has found an assignment of a scalar value (like a string, an integer or null) to a property which is an array. Either this assignment is in error or the assigned type should be added to the documentation/type hint for that property. To type hint that a parameter can be either an array or null, you can set a type hint of array and a default value of null. The PHP interpreter will then accept both an array or null for that parameter. function aContainsB(array $needle = null, array $haystack) { if (!$needle) { return false; } return array_intersect($haystack, $needle) == $haystack; } The function can be called with either null or an array for the parameter `$needle` but will only accept an array as `$haystack`.
