关于导出Excel

导出Excel，是我作为程序员来做比较无头绪的功能，还好有我的小付哥，当我还是个小菜鸟（现在还是小菜鸟），他用超强的学习能力，做功能，带我做功能
不说废话了

1.PHP-Excel，，在调用时要引入Excel5.php，和PHPExcel.php两个文件。

2.直接上代码行不行（这个代码是别人的，俺自己也写不来）

require_once '../../PHPExcel-1.7.6/PHPExcel.php';
    require_once '../../PHPExcel-1.7.6/Excel5.php';

phpexcel默认的中文处理是utf-8 因此在填充单元格时，必须转码

mb_convert_encoding('货品编码', "utf-8", "GB2312")
