    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');

    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');

    $objActSheet->setCellValue( 'C9', PHPExcel_Shared_Date::PHPToExcel( $dateTimeNow)); 
    $objActSheet->getStyle( 'C9')->getNumberFormat()->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_DATE_YYYYMMDD2);

                 foreach ($cellIterator as $cell){  //遍历列
                       if (!is_null($cell)){  //如果列不给空就得到它的坐标和计算的值
                             echo '       Cell -' ,$cell->getCoordinate(), ' -' ,$cell->getCalculatedValue() , PHP_EOL;
                      }
                }
          }
    }
     
    吧数组插入的表中
    //插入的数据3行数据
    $data= array( array('title'      => 'Excel fordummies',
                   'price'      =>17.99,
                         'quantity'  =>2
                              ),
                        array('title'       => 'PHP fordummies',
                               'price'    => 15.99,
                               'quantity'  =>1
                              ),
                        array('title'      => 'InsideOOP',
                               'price'    => 12.95,
                               '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
