phpexcel导出excel，保存本地乱码，而在服务端不是乱码问题解决方案

遇到一个奇怪的问题，phpexcel导出excel，保存本地乱码，而在服务端不是乱码问题。
 http://127.0.0.1:30983/index.php?m=report  这个是apache下的路径，可以正常保存打开excel,
 http://localhost:8080/project/index.php?m=report  这个是本地路径，不可以正常打开excel,
 其实都是在我本机上，费了一番周折，解决方案如下：

header("Content-type: text/html;charset=utf-8");
require_once 'Classes/PHPExcel.php';
require_once 'Classes/PhpExcel/Writer/Excel2007.php';
require_once 'Classes/PhpExcel/Writer/Excel5.php';
include_once 'Classes/PhpExcel/IOFactory.php'; 
//创建一个处理对象实例（此对象对于2003 2007是相同的）
$objExcel = new PHPExcel(); 
//设置属性 (这段代码无关紧要，其中的内容可以替换为你需要的)
$objExcel->getProperties()->setCreator("andy");
$objExcel->getProperties()->setLastModifiedBy("andy");
$objExcel->getProperties()->setTitle("Office 2003 XLS Test Document");
$objExcel->getProperties()->setSubject("Office 2003 XLS Test Document");
$objExcel->getProperties()->setDescription("Test document for Office 2003 XLS, generated using PHP classes.");
$objExcel->getProperties()->setKeywords("office 2003 openxml php");
$objExcel->getProperties()->setCategory("Test result file");
