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.

Did you forget a USE statement, or did you not list all dependencies? This error could be the result of: 1. Missing dependencies PHP Analyzer uses your `composer.json` file (if available) to determine the dependencies of your project and to determine all the available classes and functions. It expects the `composer.json` to be in the root folder of your repository. Are you sure this class is defined by one of your dependencies, or did you maybe not list a dependency in either the `require` or `require-dev` section? 2. Missing use statement PHP does not complain about undefined classes in `ìnstanceof` checks. For example, the following PHP code will work perfectly fine: if ($x instanceof DoesNotExist) { // Do something. } If you have not tested against this specific condition, such errors might go unnoticed.
