บกวนสอบถามหน่อยค่ะ พอดีจะต้องอ่านไฟล์ Excel แล้วเก็บข้อมูลลงฐานข้อมูล SQL Server 2008

if (file_exists($inputFileName)) { 
$inputFileType = PHPExcel_IOFactory::identify($inputFileName);  
$objReader = PHPExcel_IOFactory::createReader($inputFileType);  
$objReader->setReadDataOnly(true);  
$objPHPExcel = $objReader->load($inputFileName);  

$objWorksheet = $objPHPExcel->setActiveSheetIndex(0);
$highestRow = $objWorksheet->getHighestRow();
$highestColumn = $objWorksheet->getHighestColumn();

$headingsArray = $objWorksheet->rangeToArray('A3:'.$highestColumn.'3',null, true, true, true);
$headingsArray = $headingsArray[3];

$r = -3;

$namedDataArray = array();
for ($row = 5; $row <= $highestRow; ++$row) {
    $dataRow = $objWorksheet->rangeToArray('A'.$row.':'.$highestColumn.$row,null, true, true, true);
		  if (((isset($dataRow[$row]['B'])) && ($dataRow[$row]['B'] > '')) &&((isset($dataRow[$row]['C'])) && ($dataRow[$row]['C'] > '')) &&((isset($dataRow[$row]['D'])) && ($dataRow[$row]['D'] > '')) &&((isset($dataRow[$row]['E'])) && ($dataRow[$row]['E'] > ''))) { 
        ++$r;
        foreach($headingsArray as $columnKey => $columnHeading) {
            $namedDataArray[$r][$columnHeading] = $dataRow[$row][$columnKey];
        }
     }
  }
}
