Yii从excel文件导入数据

Question

我无法从excel文件导入数据。 Yii也没有显示任何相关错误。每当我尝试从excel导入数据时，数据都会被导入并显示在我指定的列中但我无法更新数据库。 当我尝试检查日志文件中的错误时，没有关于数据库更新的错误。我不知道哪里出错了。

public function importStuData($model)
    {

    $dispResults = []; 
    $totalSuccess = 0;

    $objPHPExcel = PHPExcel_IOFactory::load($model->importFilePath.$model->importFile);
    $sheetData = $objPHPExcel->getActiveSheet()->toArray(null, true, true, true);

    //print_r($sheetData); exit;
    unset($sheetData[1]);

    //start import student row by row
    foreach($sheetData as $k => $line){
        //print_r($line); exit;
