staticMethod.internalInterface

Code example

<?php declare(strict_types = 1);

namespace Vendor {
	/** @internal */
	interface Factory {
		public static function create(): static;
	}
}

namespace App {
	function test(): void {
		\Vendor\Factory::create(); // error: Call to static method create() of internal interface Vendor\Factory from outside its root namespace Vendor.
	}
}

Why is it reported?

A static method is being called on an interface that is marked as @internal. Internal interfaces are not part of the public API of the package that defines them. They may change or be removed in any version without prior notice.

How to fix it

Use the public API of the package instead of calling static methods on internal interfaces:

 namespace App {
 	function test(): void {
-		\Vendor\Factory::create();
+		\Vendor\PublicFactory::create();
 	}
 }

If the interface is internal to your own project and you are calling it from the same root namespace, the error will not be reported.
