Reports the usages of the entities that are marked as @internal and are located in different source roots. The usages located in the same source root are not reported.

In most cases, the reported usages should be removed or replaced with other constructs.

The folders configuration that you define for your project regulates whether an entity is treated as internal or not by PhpStorm:

• In a project without any Sources folders configured, no @internal classes' usages are marked.

• If an @internal class is located inside a configured Sources folder, the usages within the same sources folder are not marked. Usages outside this sources folder are marked.

• If an @internal class is located inside a library, all its usages outside libraries are marked.

• Inside the Test Sources folder, no @internal classes' usages are marked.
