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

I have recently been studying the Yii framework of PHP , 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 installation using composer

composer require "phpoffice/phpexcel": "*"

Copy after login

If you don’t have composer installed, you can refer to step 1.2 below

1. Introduce PHPExcel

You must first download phpexcel

You can introduce it directly in the entry file index.php, or before the controller class you define, 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->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

          ->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; )

        $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 )

    //$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.
