我正在尝试使用此创建文件我想在提交表单时将所有数据存储到.CVS文件中。我只获得前4个标签值，而我正在尝试使用添加更多并提供数据并在那时提交仅存储名称为school_1和university_1但未将数据存入.CVS文件的列名称。

$PAGENAME = basename(__FILE__);
If(isset($_POST['Submit']))

$today_date = date('m-d-Y', time());
include("processdata.php");
exportMysqlToCsv($today_date);
header('Location:save.php');
exit;
}
