Yii2 + phpstan?

Question

I have a project (PHP 8.2.6, Yii2, PHPStan). After running phpstan command, I got a list of errors that should be fixed for successful checking. Example of errors:

Access to an undefined property yii\base\Application::$request.
Access to an undefined property yii\base\Application::$response.

This errors caused because of use such code: Yii::$app->request->post() or Yii::$app->response, etc.

The first solution is to add /** @phpstan-ignore-next-line */ everywhere in the code where, for example, Yii::$app->response-> will be used.

Question, is there any other proper way to get rid of such errors?

My PHPStan configuration:

parameters:
    level: 2
    bootstrapFiles:
        - vendor/yiisoft/yii2/Yii.php
    excludePaths:
        - 'runtime/*'
        - 'vendor/*'
        - 'tests/*'
    stubFiles:
        - stubs/ActiveRecord.stub
        - stubs/Yii.stub
        - stubs/YiiRbac.stub
        - stubs/YiiBase.stub
        - stubs/YiiWeb.stub
        - stubs/YiiConsole.stub
    universalObjectCratesClasses:
        - stdClass

When debugging problem like these, you should verify what type Yii::$app is. You can troubleshoot types:

\PHPStan\dumpType(Yii::$app);

Is it what you expect, the actual type yii\base\Application? If yes, what makes you believe that yii\base\Application::$request property exists? It's probably not declared in a native way on the class. Is it a magic property defined via __get? Is there a missing @property PHPDoc above the class?

See the helpful article on the topic: https://phpstan.org/blog/solving-phpstan-access-to-undefined-property

If you need to fix wrong 3rd party PHPDocs, you can write a stub file: https://phpstan.org/user-guide/stub-files
