php操作txt，用fopen或者file_get_content可以实现，但是操作excel数据文件呢？
好在这个问题早有人想到过了，PHPExcel开源类可以帮我们无缝解决这个问题，以下是PHPExcel官方下载：http://phpexcel.codeplex.com/ 备份下载
下载代码包后，包含几个文件夹，只有Classes这个文件夹是代码，其他主要是示例、说明文档什么的，可自行参看。
博主写了一个简单函数，用于将mysql数据用php导出到excel文件中，也许可以作为速成材料：
<?php
function to_excel($sql,$excel_name)//含参数为SQL语句、导出的excel文件名
{
include_once('PHPExcel/Classes/PHPExcel.php');//包含类文件
include_once('PHPExcel/Classes/PHPExcel/Writer/Excel2007.php');//包含类文件
$objPHPExcel=new PHPExcel();//新建一个excel文件类
$re=mysql_query($sql);//执行SQL得到数据集
$i=1;
while($list=mysql_fetch_row($re))//循环一行行获取数据
{
$objPHPExcel->getActiveSheet()->setCellValue('A'.$i,$list[0]);//excel的第A列第i行写入$list[0]
$objPHPExcel->getActiveSheet()->setCellValue('B'.$i,$list[1]);//依次类推
$objPHPExcel->getActiveSheet()->setCellValue('C'.$i,$list[2]);
$objPHPExcel->getActiveSheet()->setCellValue('D'.$i,$list[3]);
$objPHPExcel->getActiveSheet()->setCellValue('E'.$i,$list[4]);
$objPHPExcel->getActiveSheet()->setCellValue('F'.$i,$list[5]);
$objPHPExcel->getActiveSheet()->setCellValue('G'.$i,$list[6]);
$objPHPExcel->getActiveSheet()->setCellValue('H'.$i,$list[7]);
$objPHPExcel->getActiveSheet()->setCellValue('I'.$i,$list[8]);
$i++;
}
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);//将excel数据对象实例化为excel文件对象
$objWriter->save($excel_name.".xlsx");//导出并写入当前目录，按照$excel_name命名
echo "OK!已导出为".$excel_name;
}
?>
附PHPExcel类详细使用说明：
/**————————基础操作—————————————**/
//包含类文件
include ‘PHPExcel.php’;
include ‘PHPExcel/Writer/Excel2007.php’;//或者include ‘PHPExcel/Writer/Excel5.php’; 用于输出.xls的
//创建一个excel
$objPHPExcel = new PHPExcel();
//保存excel—2007格式
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);//或者$objWriter = new PHPExcel_Writer_Excel5($objPHPExcel); 非2007格式
$objWriter->save(”xxx.xlsx”);
//直接输出到浏览器
$objWriter = new PHPExcel_Writer_Excel5($objPHPExcel);
header(”Pragma: public”);
header(”Expires: 0″);
