首先到phpexcel官网上下载最新的phpexcel类，下周解压缩一个classes文件夹，里面包含了PHPExcel.php和PHPExcel的文件夹，这个类文件和文件夹是我们需要的，把classes解压到你项目的一个目录中，重名名为phpexcel，开始喽，（代码都摘自自带实例）

程序部分

require_once './phpexcel/PHPExcel.php';

//首先创建一个新的对象 PHPExcelobject
$objPHPExcel = new PHPExcel();

//设置文件的一些属性，在xls文件——>属性——>详细信息里可以看到这些值，xml表格里是没有这些值的
$objPHPExcel
->getProperties() //获得文件属性对象，给下文提供设置资源
->setCreator( "MaartenBalliauw") //设置文件的创建者
->setLastModifiedBy( "MaartenBalliauw") //设置最后修改者
->setTitle( "Office2007 XLSX Test Document" ) //设置标题
->setSubject( "Office2007 XLSX Test Document" ) //设置主题
->setDescription( "Test document for Office2007 XLSX, generated using PHP classes.") //设置备注
->setKeywords( "office 2007 openxmlphp") //设置标记
->setCategory( "Test resultfile"); //设置类别
// 位置aaa *为下文代码位置提供锚
//给表格添加数据
$objPHPExcel->setActiveSheetIndex(0) //设置第一个内置表（一个xls文件里可以有多个表）为活动的
->setCellValue( 'A1', 'Hello' ) //给表的单元格设置数据
->setCellValue( 'B2', 'world!' ) //数据格式可以为字符串
->setCellValue( 'C1',12) //数字型
->setCellValue( 'D2',12) //
->setCellValue( 'D3', true ) //布尔型
->setCellValue( 'D4', '=SUM(C1:D2)' );//公式

//得到当前活动的表,注意下文教程中会经常用到$objActSheet
$objActSheet =$objPHPExcel->getActiveSheet();
// 位置bbb *为下文代码位置提供锚
//给当前活动的表设置名称
$objActSheet->setTitle('Simple2222');
代码还没有结束，可以复制下面的代码来决定我们将要做什么

我们将要做的是
1,直接生成一个文件
$objWriter =PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('myexchel.xlsx');

2、提示下载文件
excel 2003 .xls
//生成2003excel格式的xls文件
header('Content-Type:application/vnd.ms-excel');
header('Content-Disposition:attachment;filename="01simple.xls"');
header('Cache-Control:max-age=0');

$objWriter =PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');
exit;

excel 2007 .xlsx
//生成2007excel格式的xlsx文件
header('Content-Type:application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition:attachment;filename="01simple.xlsx"');
header('Cache-Control:max-age=0');

$objWriter =PHPExcel_IOFactory:: createWriter($objPHPExcel, 'Excel2007');
$objWriter->save( 'php://output');
exit;

pdf 文件
// 下载一个pdf文件
header('Content-Type:application/pdf');
header('Content-Disposition:attachment;filename="01simple.pdf"');
header('Cache-Control:max-age=0');

$objWriter =PHPExcel_IOFactory::createWriter($objPHPExcel, 'PDF');
$objWriter->save('php://output');
exit;
// 生成一个pdf文件
$objWriter =PHPExcel_IOFactory::createWriter($objPHPExcel, 'PDF');
$objWriter->save('a.pdf');

CSV文件
$objWriter =PHPExcel_IOFactory::createWriter($objPHPExcel, 'CSV')->setDelimiter(',' ) //设置分隔符
->setEnclosure('"' ) //设置包围符
->setLineEnding("\r\n" )//设置行分隔符
->setSheetIndex(0) //设置活动表
->save(str_replace('.php' , '.csv' ,__FILE__));

HTML文件
$objWriter =PHPExcel_IOFactory::createWriter($objPHPExcel, 'HTML'); //将$objPHPEcel对象转换成html格式的
$objWriter->setSheetIndex(0); //设置活动表
//$objWriter->setImagesRoot('http://www.example.com');

'quantity' =>1
)
);
$baseRow=5; //指定插入到第5行后
foreach($data as $r => $dataRow){
$row= $baseRow +$r; //$row是循环操作行的行号
$objPHPExcel->getActiveSheet()->insertNewRowBefore($row,1); //在操作行的号前加一空行，这空行的行号就变成了当前的行号
//对应的咧都附上数据和编号
$objPHPExcel->getActiveSheet()->setCellValue( 'A'.$row,$r+1);
$objPHPExcel->getActiveSheet()->setCellValue( 'B'.$row,$dataRow['title']);
$objPHPExcel->getActiveSheet()->setCellValue( 'C'.$row,$dataRow['price']);
$objPHPExcel->getActiveSheet()->setCellValue( 'D'.$row,$dataRow['quantity']);
$objPHPExcel->getActiveSheet()->setCellValue( 'E'.$row, '=C'.$row.'*D' .$row);
}
$objPHPExcel->getActiveSheet()->removeRow($baseRow-1,1); //最后删去第4行，这是示例需要，在此处为大家提供删除实例
