excel無法在瀏覽器輸出。

這是我的程式碼

<?php

$dir=dirname(_FILE_);

require $dir."/PHPExcel/PHPExcel.php" ;

$objPHPExcel=new PHPExcel();

$objSheet=$objPHPExcel->getActiveSheet();

$objSheet->setTitle("demo") ;

//$objSheet->setCellValue("A1","可可")->setCellValue("b1","蛋蛋");

#$array=array(

array("姓名","年齡"),

array("大可","58")

);

$objSheet ->fromArray($array);

$objWriter=PHPExcel_IOFactory::createWriter($objPHPExcel,"Excel5");

##$objWriter = new PHPExcel_Writer_ccel$objWriter = new PHPExcel_Writer_ccel);

header('Content-Type: application/vnd.ms-excel');

header('Content-Disposition: attachment;filename="ch3.xls"') ;

header('Cache-Control: max-age=0');

#$objWriter->save("php://output");

#?> 但是產生的xls檔案確實這個東西：
