		0 ignored issues – show Coding Style Compatibility introduced 2016-06-30 14:29 UTC by Report Bug Copy Issue Report Each trait must be in a namespace of at least one level (a top-level vendor name) You can fix this by adding a namespace to your class: namespace YourVendor; class YourClass { } When choosing a vendor namespace, try to pick something that is not too generic to avoid conflicts with other libraries.

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...
