Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation. You can also find more detailed suggestions in the “Code” section of your repository. Loading history...

			0 ignored issues – show Documentation introduced 2016-03-01 03:50 UTC by Report Bug Copy Issue Report Should the type for parameter `$values` not be `array\|\Traversable\|null`? Also, consider making the array more specific, something like `array<String>`, or `String[]`. This check looks for `@param` annotations where the type inferred by our type inference engine differs from the declared type. It makes a suggestion as to what type it considers more descriptive. In addition it looks for parameters that have the generic type `array` and suggests a stricter type like `array<String>`. Most often this is a case of a parameter that can be null in addition to its declared types. Loading history...
