How to export Excel files from PHPExcel in Yii2 framework

This article mainly introduces the relevant information about using PHPExcel to export Excel files in the Yii2 framework. It has certain reference value. Interested friends can refer to it. I hope it can help everyone.

Recently I have been studying the Yii framework of PHP and I like it very much. When I encountered the problem of exporting Excel, I studied it and came up with the following method:

The simplest method Use composer to install

composer require "phpoffice/phpexcel": "*"

If composer is not installed, you can refer to step 1.2 below

1. Introduce PHPExcel

First you need to download the phpexcel address: https://github.com/PHPOffice/PHPExcel/archive/1.8.1.zip

You can introduce it directly into the entry file index.php , or it can be introduced before the controller class you defined, as long as it is introduced before you use it

require dirname(dirname(__FILE__)).'/excel/PHPExcel.php';

Or you can modify the corresponding namespace in the phpexcel class .

2. Modify the Autoloader.php file in the PHPExcel code directory according to the following code, and compare the source file to:

public static function Register() {
  $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;
}

above In the function, the original code is commented out.

3. The following code outputs Excel, as well as some commonly used property settings, in the controller:

##

public function actionExport()
{
    $objectPHPExcel = new PHPExcel();
    $objectPHPExcel->setActiveSheetIndex(0);
  
    $page_size = 52;
    $model = new NewsSearch();
    $dataProvider = $model->search();
    $dataProvider->setPagination(false);
    $data = $dataProvider->getData();
    $count = $dataProvider->getTotalItemCount();
    $page_count = (int)($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');

After the code is executed, Excel will be generated directly , and prompts to download or open.
