How to export Excel files from PHPExcel in Yii2 framework-PHP Tutorial-php.cn

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": "*"

Copy after login

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__)).&#39;/excel/PHPExcel.php&#39;;

Copy after login

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);
    $functions = array_merge(array(array(&#39;PHPExcel_Autoloader&#39;,&#39;Load&#39;)),$functions);
  foreach ( $functions as $function)
    $x = spl_autoload_register($function);
    return $x;
}

Copy after login

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(&#39;B1:G1&#39;);
        $objectPHPExcel->getActiveSheet()->setCellValue(&#39;B1&#39;,&#39;产品信息表&#39;);
  
        $objectPHPExcel->setActiveSheetIndex(0)->setCellValue(&#39;B2&#39;,&#39;产品信息表&#39;);
        $objectPHPExcel->setActiveSheetIndex(0)->setCellValue(&#39;B2&#39;,&#39;产品信息表&#39;);
        $objectPHPExcel->setActiveSheetIndex(0)->getStyle(&#39;B1&#39;)->getFont()->setSize(24);
        $objectPHPExcel->setActiveSheetIndex(0)->getStyle(&#39;B1&#39;)
          ->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
  
        $objectPHPExcel->setActiveSheetIndex(0)->setCellValue(&#39;B2&#39;,&#39;日期：&#39;.date("Y年m月j日"));
        $objectPHPExcel->setActiveSheetIndex(0)->setCellValue(&#39;G2&#39;,&#39;第&#39;.$current_page.&#39;/&#39;.$page_count.&#39;页&#39;);
        $objectPHPExcel->setActiveSheetIndex(0)->getStyle(&#39;G2&#39;)
          ->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_RIGHT);
          
        //表格头的输出
        $objectPHPExcel->getActiveSheet()->getColumnDimension(&#39;A&#39;)->setWidth(5);
        $objectPHPExcel->setActiveSheetIndex(0)->setCellValue(&#39;B3&#39;,&#39;编号&#39;);
        $objectPHPExcel->getActiveSheet()->getColumnDimension(&#39;B&#39;)->setWidth(6.5);
        $objectPHPExcel->setActiveSheetIndex(0)->setCellValue(&#39;C3&#39;,&#39;名称&#39;);
        $objectPHPExcel->getActiveSheet()->getColumnDimension(&#39;C&#39;)->setWidth(17);
        $objectPHPExcel->setActiveSheetIndex(0)->setCellValue(&#39;D3&#39;,&#39;生产厂家&#39;);
        $objectPHPExcel->getActiveSheet()->getColumnDimension(&#39;D&#39;)->setWidth(22);
        $objectPHPExcel->setActiveSheetIndex(0)->setCellValue(&#39;E3&#39;,&#39;单位&#39;);
        $objectPHPExcel->getActiveSheet()->getColumnDimension(&#39;E&#39;)->setWidth(15);
        $objectPHPExcel->setActiveSheetIndex(0)->setCellValue(&#39;F3&#39;,&#39;单价&#39;);
        $objectPHPExcel->getActiveSheet()->getColumnDimension(&#39;F&#39;)->setWidth(15);
        $objectPHPExcel->setActiveSheetIndex(0)->setCellValue(&#39;G3&#39;,&#39;在库数&#39;);
        $objectPHPExcel->getActiveSheet()->getColumnDimension(&#39;G&#39;)->setWidth(15);
          
        //设置居中
        $objectPHPExcel->getActiveSheet()->getStyle(&#39;B3:G3&#39;)
          ->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
  
        //设置边框
        $objectPHPExcel->getActiveSheet()->getStyle(&#39;B3:G3&#39; )
          ->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
        $objectPHPExcel->getActiveSheet()->getStyle(&#39;B3:G3&#39; )
          ->getBorders()->getLeft()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
        $objectPHPExcel->getActiveSheet()->getStyle(&#39;B3:G3&#39; )
          ->getBorders()->getRight()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
        $objectPHPExcel->getActiveSheet()->getStyle(&#39;B3:G3&#39; )
          ->getBorders()->getBottom()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
        $objectPHPExcel->getActiveSheet()->getStyle(&#39;B3:G3&#39; )
          ->getBorders()->getVertical()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
  
        //设置颜色
        $objectPHPExcel->getActiveSheet()->getStyle(&#39;B3:G3&#39;)->getFill()
          ->setFillType(PHPExcel_Style_Fill::FILL_SOLID)->getStartColor()->setARGB(&#39;FF66CCCC&#39;);
          
      }
      //明细的输出
      $objectPHPExcel->getActiveSheet()->setCellValue(&#39;B&#39;.($n+4) ,$product->id);
      $objectPHPExcel->getActiveSheet()->setCellValue(&#39;C&#39;.($n+4) ,$product->product_name);
      $objectPHPExcel->getActiveSheet()->setCellValue(&#39;D&#39;.($n+4) ,$product->product_agent->name);
      $objectPHPExcel->getActiveSheet()->setCellValue(&#39;E&#39;.($n+4) ,$product->unit);
      $objectPHPExcel->getActiveSheet()->setCellValue(&#39;F&#39;.($n+4) ,$product->unit_price);
      $objectPHPExcel->getActiveSheet()->setCellValue(&#39;G&#39;.($n+4) ,$product->library_count);
      //设置边框
      $currentRowNum = $n+4;
      $objectPHPExcel->getActiveSheet()->getStyle(&#39;B&#39;.($n+4).&#39;:G&#39;.$currentRowNum )
          ->getBorders()->getTop()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
      $objectPHPExcel->getActiveSheet()->getStyle(&#39;B&#39;.($n+4).&#39;:G&#39;.$currentRowNum )
          ->getBorders()->getLeft()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
      $objectPHPExcel->getActiveSheet()->getStyle(&#39;B&#39;.($n+4).&#39;:G&#39;.$currentRowNum )
          ->getBorders()->getRight()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);
      $objectPHPExcel->getActiveSheet()->getStyle(&#39;B&#39;.($n+4).&#39;:G&#39;.$currentRowNum )
          ->getBorders()->getBottom()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);

      $n = $n +1;  
    }
  
    //设置分页显示
    //$objectPHPExcel->getActiveSheet()->setBreak( &#39;I55&#39; , PHPExcel_Worksheet::BREAK_ROW );
    //$objectPHPExcel->getActiveSheet()->setBreak( &#39;I10&#39; , PHPExcel_Worksheet::BREAK_COLUMN );
    $objectPHPExcel->getActiveSheet()->getPageSetup()->setHorizontalCentered(true);
    $objectPHPExcel->getActiveSheet()->getPageSetup()->setVerticalCentered(false);
  
  
    ob_end_clean();
    ob_start();
  
    header(&#39;Content-Type : application/vnd.ms-excel&#39;);
    header(&#39;Content-Disposition:attachment;filename="&#39;.&#39;产品信息表-&#39;.date("Y年m月j日").&#39;.xls"&#39;);
    $objWriter= PHPExcel_IOFactory::createWriter($objectPHPExcel,&#39;Excel5&#39;);
    $objWriter->save(&#39;php://output&#39;);

Copy after login

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