Duplication introduced by
This code seems to be duplicated across your project.

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.

Bug introduced by
The variable $dataTransfer does not exist. Did you mean $backupDataTransfer?

This check looks for variables that are accessed but have not been defined. It raises an issue if it finds another variable that has a similar name.

The variable may have been renamed without also renaming all references.
