Migrating to php 8.2 - how to solve deprecated dynamics properties

Hi,
I am trying to upgrade to php 8.2, but running into the deprecated dynamic properties issues and I am not sure how to solve it.
In my BaseController, I prepare some elements I need within the views, but that generates the deprecated error. Here how it looks like:

PHP Code:

abstract class BaseController extends Controller
{

protected $request;

protected $helpers = [];

    public function initController(RequestInterface $request, ResponseInterface $response, LoggerInterface $logger)
    {
        // Do Not Edit This Line
        parent::initController($request, $response, $logger);

        // Preload any models, libraries, etc, here.
        helper('html');

        // E.g.: $this->session = \Config\Services::session();
        $this->viewData['locale'] = $request->getLocale();
        $this->viewData['supportedLocales'] = $request->config->supportedLocales;
        $this->viewData['currentMenu'] = '';
        $this->viewData['axeptioID'] = getenv('axeptioID');
        $this->viewData['axeptioCookiesVersion'] = getenv('axeptioCookiesVersion');

        $this->session = \Config\Services::session();
        $this->session->set('locale',$request->getLocale());


    }
} 


I tried adding as suggested here https://stitcher.io/blog/deprecated-dyna...-in-php-82 the built-in attribute, but without success.

PHP Code:

#[AllowDynamicProperties]
abstract class BaseController extends Controller
{
... 


{What is the best way to solve this? Thanks for your help

Try to add:

PHP Code:

use AllowDynamicProperties; 


But the best way is to define the properties you use.
Because dynamic properties are deprecated.

Try to add:

PHP Code:

use AllowDynamicProperties; 


But the best way is to define the properties you use.
Because dynamic properties are deprecated.

Use AllowDynamicProperties still does not work (or maybe I did not place it where it should for it to work. 

But I now understand what you meant by "define properties".  

PHP Code:

protected $viewData = [];
protected $session = []; 


solved my issue.

Thanks

After that, I got $_SESSION errors, do I need to update system folder something like change session.name to session.id?

What is the $_SESSION errors?
Can you show the exact error messages?

This worked for me as well.

Adding

PHP Code:

protected $session = []; 


to my base controller allowed the this statement to work in the base controller initController method:

PHP Code:

$this->session = \Config\Services::session(); 


Thanks so much to kcs for the question, and to kenjis for the solution.
