使用Spreadsheet_Excel_Reader php从excel文件读取空单元格

Question

我想读取一个空单元格，但无法从excel文件读取，这是我的代码

if(isset($_REQUEST['submitid']) && $_REQUEST['submitid']=='donor_file'){
global $con;

$userid = $_SESSION['Cont_ID'];
$company_id = $_SESSION['Company_ID'];
$cdate = date('Y-m-d h:i:s');
$status = 1;

//Donor File Attachment
$F_filePath="../../uploads/ds_information/donor/";
$_FILES['donor_attachment']['name'];
if ($_FILES['donor_attachment']['name']!=""){
$donor_attachment = date('dmyhis')."_".$userid."_".$company_id."_".$_FILES['donor_attachment']['name'];
move_uploaded_file($_FILES['donor_attachment']['tmp_name'], $F_filePath.$donor_attachment);

$filepath = "../../uploads/ds_information/donor/".$donor_attachment;

我希望在获取空单元格时将该单元格替换为空白以发送数据库值。当我回显此echo sizeof($DataArray);时，然后返回其大小为34的单元格，其中没有空单元格。有没有办法从excel文件中获取空单元格并替换blcnk以便将值发送到数据库。
