php - arrayObject の通知エラー

Question

こんにちは、多次元配列とそれらの設定に関して、このクラスに問題があり、なぜこのように動作するのか理解できません...修正を手伝ってくれる人はいますか?

いくつかの使用例:

echo $config->session->gcDivisor;
echo $config['session']['gcDivisor'];
$config['logged'] = '1';
$config->logged = '1';
$config['user']['logged'] = '1';
$config->user->logged = '1';

各行のエラー
