如何解決此問題，我找不到任何答案

Answer 1

我有同樣的錯誤。 我使用會話數組對其進行了更正

Answer 2

foreach ($output['tab_displayId'] as $id_display => $id_param){
                $test = new ClParaWidget($id_param, $id_display);
                $output[$id_display] = $test->toString($id_display);
                if (Yii::app()->session['S' . $id_display] != $output[$id_display])
                    Yii::app()->session['S' . $id_display] = $output[$id_display];
            } 

Answer 3

我給更多的解釋。 如果我想在會話值中保存一個數組：

Yii::app()->session['data'] = $array_data;

有時，此代碼返回錯誤：

Fatal error: Uncaught exception 'Exception' with message 'Serialization of 'SimpleXMLElement' is not allowed' in C:\xampp\htdocs\t9l_loyaltyprogram\common\lib\Yii\web\CHttpSession.php:138 Stack trace:

為此，我建議使用如下所示的會話數組：

foreach ($array_data as $id => $data)       
  Yii::app()->session['S_' . $id] = $data;
