我正在使用 PHPExcel 通过 CI 和grocery_CRUD 从 MySQL 中的 Excel 上传数据。这是我的方式：

parent::__construct();
}

//load our new Lib Excel library as object excel
$this->load->library('Lib_excel', null, 'excel');
// load excel file
$objPHPExcel = $this->excel->load($excelFileName);
// get active sheets
$objWorksheet = $objPHPExcel->getActiveSheet();
// get highest row column

for ($i = $startRow; $i < $lastRow; $i++) {
$colB = $objPHPExcel->getActiveSheet()->getCell($columnName . $i)->getValue();
if ($colB == NULL || $colB == '') {

}

// get excel data with range e.g. (B2:B56)
$cellValues = $objPHPExcel->getActiveSheet()->rangeToArray("$columnName$startRow:$columnName$lastRow");
