PHPExcel 是用来操作Office Excel 文档的一个PHP类库，它基于微软的OpenXML标准和PHP语言。可以使用它来读取、写入不同格式的电子表格。整体来说是一个不错的Excel操作类。
下面是这个类的一些操作说明。

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();
// 输出Excel表格到浏览器下载
header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="abc.xls"');
header('Cache-Control: max-age=0');
// If you're serving to IE 9, then the following may be needed
header('Cache-Control: max-age=1');
// If you're serving to IE over SSL, then the following may be needed
header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
header('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT'); // always modified
header('Cache-Control: cache, must-revalidate'); // HTTP/1.1
header('Pragma: public'); // HTTP/1.0
$objWriter = new PHPExcel_Writer_Excel5($objPHPExcel);
$objWriter->save('php://output');

设置excel的属性：

//创建人
$objPHPExcel->getProperties()->setCreator("Maarten Balliauw");
//最后修改人
$objPHPExcel->getProperties()->setLastModifiedBy("Maarten Balliauw");
//标题
$objPHPExcel->getProperties()->setTitle("Office 2007 XLSX Test Document");
//题目
$objPHPExcel->getProperties()->setSubject("Office 2007 XLSX Test Document");
//描述
$objPHPExcel->getProperties()->setDescription("Test document for Office 2007 XLSX, generated using PHP classes.");
//关键字
$objPHPExcel->getProperties()->setKeywords("office 2007 openxml php");
//种类
$objPHPExcel->getProperties()->setCategory("Test result file");
