		0 ignored issues – show Bug Best Practice introduced 2019-04-06 23:10 UTC by Report Bug Copy Issue Report The expression `$middlewares` of type `array<integer,Tarantool\...\Middleware\Middleware>` is implicitly converted to a boolean; are you sure this is intended? If so, consider using `! empty($expr)` instead to make it clear that you intend to check for an array without elements. This check marks implicit conversions of arrays to boolean values in a comparison. While in PHP an empty array is considered to be equal (but not identical) to false, this is not always apparent. Consider making the comparison explicit by using `empty(..)` or `! empty(...)` instead. Loading history...
