PHPExcel export excel drop-down menu how to do excel2013 official download excel2007

// PHPExcel export steps:
// One: Introduce the official website download class library
// Two: Instantiate the PHPExcel class (create a new excel table)
// Three: createSheet() method, setActveSheetIndex method, getActiveSheel Method (create a built-in table in the sheet)
// Four: setCellValue() method (fill data)
// Five: PHPExcel_IOFactory::createWriter() method, save() method (save the file)
$dir =dirname(__FILE__); //Find the path where the current script is located
require $dir."/PHPExcel/PHPExcel.php";//Introduce the file
$objPHPExcel=new PHPExcel();//Instantiate the PHPExcel class, which is equivalent to creating a new excel table on the desktop
$objSheet=$objPHPExcel->getActiveSheet();//Get the operation object of the current active sheet
$objSheet->setTitle("demo");//Set a name for the current active sheet
/*$objSheet-> ;setCellValue("A1","Name")->setCellValue("B1","Score");//Fill data into the current active sheet
$objSheet->setCellValue("A2","Zhang San") ->setCellValue("B1","98");//Fill data into the current active sheet*/
//Array format
$array=array(
                                                                    using using use using using ‐           ‐       ‐                                                   - "score"),
array("","张三","98"),
array("","李思","59"),
);
$objSheet->fromArray($array ); // Directly load data blocks to fill
/*
* Tip: If the amount of data in this array is large, the fromArray() method will occupy too much memory and will report a memory error.
It is recommended to use the setCellValue method
*/
$objWriter=五：PHPExcel_IOFactory::createWriter($objPHPExcel,"Excel2007");//Generate excel file according to the specified format
$objWriter->save($dir."demo.xlsx");
?>
