Why an empty array?

Question

PHP

Can you tell me why the array can be empty? those. when you click on the button named save, the record is safely added to the associated table. but when you try to get this $_SESSION['logged_user']->ownPapkyList method - the array is empty. Is there a gross error in this entry? because I'm learning php for a couple of days. It's just that if there was an error somewhere else, the record would not be added, right?

<?php 
    $data = $_POST;
    if (isset($data['save'])) {

      $papka = R::dispense('papki');
      $papka->imya = $data['papkaname'];
      
      $_SESSION['logged_user']->ownPapkyList[] = $papka;	
      R::store($_SESSION['logged_user']);
    } 

    print_r($_SESSION['logged_user']->ownPapkyList);
    
  ?>

decided.
the solution was in the error of writing ownPapkyList over the place of ownPapkiList. because the linked page was called exactly with the ending in i as you can see from the line $papka = R::dispense('papki'); lose everything works
