Yii框架中使用PHPExcel导出Excel文件

最近在研究PHP的Yii框架，很喜欢，碰到导出Excel的问题，研究了一下，就有了下面的方法：

 

1、首先在config\main.php中添加对PHPExcel的引用，我的方式是这样：

 

  //  autoloading model and component classes
    'import'=> array(
         /* 'application.modules.srbac.controllers.SBaseController', */        
        'application.models.*',
        'application.components.*',
        'application.extensions.phpexcel.*',
        
    ),

 

另外也有人用components 这个配置，但是我的有问题，所以就用上面的方法。

 

2、按照下面的代码修改PHPExcel代码目录里的Autoloader.php文件：

 public static function Register() {

         /* if (function_exists('__autoload')) {
            //    Register any existing autoloader function with SPL, so we don't get any clashes
            spl_autoload_register('__autoload');
        }
        //    Register ourselves with SPL
        return spl_autoload_register(array('PHPExcel_Autoloader', 'Load')); */
         $functions = spl_autoload_functions();
             foreach (  $functions  as   $function)
                spl_autoload_unregister( $function);
             $functions =  array_merge( array( array('PHPExcel_Autoloader','Load')), $functions);
             foreach (  $functions  as  $function)
                 $x = spl_autoload_register( $function);
             return  $x;

    }     //     function Register()

上面的函数中，注释掉的是原有的代码。

 

3、下面的代码是输出Excel，以及一些常用的属性设置，在你的controller中：

     /*

    导出为Excel
     */
     public   function actionExport()
    {
         $objectPHPExcel =  new PHPExcel();
         $objectPHPExcel->setActiveSheetIndex(0);

         $page_size = 52;
         // 数据的取出
         $model = Yii::app()->session['printdata'];

         $dataProvider =  $model->search();

         $dataProvider->setPagination( false);
         $data =  $dataProvider->getData();
         $count =  $dataProvider->getTotalItemCount();
         // 总页数的算出
         $page_count = (int)( $count/ $page_size) +1;
         $current_page = 0;

         $n = 0;
         foreach (  $data  as  $product )
        {
             if (  $n %  $page_size === 0 )
            {
                 $current_page =  $current_page +1;

                 // 报表头的输出
                 $objectPHPExcel->getActiveSheet()->mergeCells('B1:G1');
                 $objectPHPExcel->getActiveSheet()->setCellValue('B1','产品信息表');

                 $objectPHPExcel->setActiveSheetIndex(0)->setCellValue('B2','产品信息表');
                 $objectPHPExcel->setActiveSheetIndex(0)->setCellValue('B2','产品信息表');
                 $objectPHPExcel->setActiveSheetIndex(0)->getStyle('B1')->getFont()->setSize(24);
                 $objectPHPExcel->setActiveSheetIndex(0)->getStyle('B1')
                    ->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);

                 $objectPHPExcel->setActiveSheetIndex(0)->setCellValue('B2','日期：'. date("Y年m月j日"));
                 $objectPHPExcel->setActiveSheetIndex(0)->setCellValue('G2','第'. $current_page.'/'. $page_count.'页');
                 $objectPHPExcel->setActiveSheetIndex(0)->getStyle('G2')
                    ->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);
                
                 // 表格头的输出
                 $objectPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(5);
                 $objectPHPExcel->setActiveSheetIndex(0)->setCellValue('B3','编号');
                 $objectPHPExcel->getActiveSheet()->getColumnDimension('B')->setWidth(6.5);
                 $objectPHPExcel->setActiveSheetIndex(0)->setCellValue('C3','名称');
                 $objectPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth(17);
                 $objectPHPExcel->setActiveSheetIndex(0)->setCellValue('D3','生产厂家');
                 $objectPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(22);
                 $objectPHPExcel->setActiveSheetIndex(0)->setCellValue('E3','单位');
                 $objectPHPExcel->getActiveSheet()->getColumnDimension('E')->setWidth(15);
                 $objectPHPExcel->setActiveSheetIndex(0)->setCellValue('F3','单价');
                 $objectPHPExcel->getActiveSheet()->getColumnDimension('F')->setWidth(15);
                 $objectPHPExcel->setActiveSheetIndex(0)->setCellValue('G3','在库数');
                 $objectPHPExcel->getActiveSheet()->getColumnDimension('G')->setWidth(15);
                
                 // 设置居中
                 $objectPHPExcel->getActiveSheet()->getStyle('B3:G3')
                    ->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);

                 // 设置边框
                 $objectPHPExcel->getActiveSheet()->getStyle('B3:G3' )
                    ->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
                 $objectPHPExcel->getActiveSheet()->getStyle('B3:G3' )
                    ->getBorders()->getLeft()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
                 $objectPHPExcel->getActiveSheet()->getStyle('B3:G3' )
                    ->getBorders()->getRight()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
                 $objectPHPExcel->getActiveSheet()->getStyle('B3:G3' )
                    ->getBorders()->getBottom()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
                 $objectPHPExcel->getActiveSheet()->getStyle('B3:G3' )
                    ->getBorders()->getVertical()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);

                 // 设置颜色
                 $objectPHPExcel->getActiveSheet()->getStyle('B3:G3')->getFill()
                    ->setFillType(PHPExcel_Style_Fill::FILL_SOLID)->getStartColor()->setARGB('FF66CCCC');
                
            }
             // 明细的输出
             $objectPHPExcel->getActiveSheet()->setCellValue('B'.( $n+4) , $product->id);
             $objectPHPExcel->getActiveSheet()->setCellValue('C'.( $n+4) , $product->product_name);
             $objectPHPExcel->getActiveSheet()->setCellValue('D'.( $n+4) , $product->product_agent->name);
             $objectPHPExcel->getActiveSheet()->setCellValue('E'.( $n+4) , $product->unit);
             $objectPHPExcel->getActiveSheet()->setCellValue('F'.( $n+4) , $product->unit_price);
             $objectPHPExcel->getActiveSheet()->setCellValue('G'.( $n+4) , $product->library_count);
             // 设置边框
             $currentRowNum =  $n+4;
             $objectPHPExcel->getActiveSheet()->getStyle('B'.( $n+4).':G'. $currentRowNum )
                    ->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
             $objectPHPExcel->getActiveSheet()->getStyle('B'.( $n+4).':G'. $currentRowNum )
                    ->getBorders()->getLeft()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
             $objectPHPExcel->getActiveSheet()->getStyle('B'.( $n+4).':G'. $currentRowNum )
                    ->getBorders()->getRight()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
             $objectPHPExcel->getActiveSheet()->getStyle('B'.( $n+4).':G'. $currentRowNum )
                    ->getBorders()->getBottom()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
             $objectPHPExcel->getActiveSheet()->getStyle('B'.( $n+4).':G'. $currentRowNum )
                    ->getBorders()->getVertical()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
             $n =  $n +1;    
        }

         // 设置分页显示
        //$objectPHPExcel->getActiveSheet()->setBreak( 'I55' , PHPExcel_Worksheet::BREAK_ROW );
        //$objectPHPExcel->getActiveSheet()->setBreak( 'I10' , PHPExcel_Worksheet::BREAK_COLUMN );
         $objectPHPExcel->getActiveSheet()->getPageSetup()->setHorizontalCentered( true);
         $objectPHPExcel->getActiveSheet()->getPageSetup()->setVerticalCentered( false);


         ob_end_clean();
         ob_start();

         header('Content-Type : application/vnd.ms-excel');
         header('Content-Disposition:attachment;filename="'.'产品信息表-'. date("Y年m月j日").'.xls"');
         $objWriter= PHPExcel_IOFactory::createWriter( $objectPHPExcel,'Excel5');
         $objWriter->save('php://output');

    } 

 

代码执行后，会直接生成Excel，并提示下载或打开。
