如果使用 Excel5 ，输出的内容应该是GBK编码

下面就是php导出excel的程序

<?php
ini_set("display_errors",1);//是否显示报错信息
set_include_path(get_include_path() . PATH_SEPARATOR . '1.6.6/Classes/');//设置此页面包含路径
include "PHPExcel/Writer/Excel5.php"; // 用于其他低版本xls 
//创建一个excel
$objPHPExcel = new PHPExcel();
?>

<?    
//设置PHPExcel类库的include path    
set_include_path('.'. PATH_SEPARATOR .    
                 'i:\Zeal\PHP_LIBS' . PATH_SEPARATOR .    
                  get_include_path());
