php - 我用于将 MySQL 模式导出到 .xls 的 PHP 脚本转储 HTML 工件

Question

如标题所述 - 我编写了一个小脚本，可以将包含数据的 SQL 生成表导出到 Excel 可读的 .xls 文件中。但是，当我导出数据时，出于某种原因，页脚和页眉也被转储到包含图像和所有内容的 .xls 文件中。

这是我导出 MySQL 数据的脚本:

if(isset($_POST['download']))
    { 
        $q = "SELECT * FROM completed_tasks ORDER BY PRIORITY DESC";
        $result = mysqli_query($conn, $q);

        if(mysqli_num_rows($result) > 0)
        {
            $output .= "<table class='sqltable'>
                        <tr class='sqltable'> 
                            <th class='sqltable'>From:</th>
                            <th class='sqltable'>Department:</th>
                            <th class='sqltable'>Name of the task:</th>                                                                             
                            <th class='sqltable'>Description:</th>          
                            <th class='sqltable'>Priority:</th>
                            <th class='sqltable'>Time elapsed:</th>      
                            <th class='sqltable'>Completed by:</th>                                       
                            <th class='sqltable'>Notes:</th>        
                        </tr>";

            // output data of each row
            while($row = $result->fetch_assoc()) 
            {
                $output .= "<tr class='sqltable'>"; 
                $output .=   "<td class='sqlcell'>".$row["FROM"]."</td>"; 
                $output .=   "<td class='sqlcell'>".$row["DEPT"]." </td>" 
                $output .=   "<td class='sqlcell'>".$row["TASK_NAME"]."</td>";
                $output .=   "<td class='sqlcell'>".$row["TASK"]."</td>";
                $output .=   "<td class='sqlcell'>". $row["PRIORITY"]."</td>";  
                $output .=   "<td class='sqlcell'>".$row["TIME_COMPLETED"]."</td>";
                $output .=   "<td class='sqlcell'>".$row["COMPLETED_BY"]."</td>";                           
                $output .=   "<td class='sqlcell'>".$row["TASK_RESOLVE"]."</td>";
                $output .=   "</tr>";
            } 
            $output .= "</table>"; 

            header('Content-Type: application/xls');
            header('Content-Disposition: attachment; filename=download.xls');
            echo $output;
        }

编辑:我刚刚意识到我生成的 .xls 文件也在寻找 .css 样式配置。

在 php 中使用 PHPSpreadsheet 构建 excell

PHPSpreadSheet is a library for Excell An open source project Build support Microsoft Excell 2007

这是链接 PHPSpreadSheet 从 composer 安装在命令行上

composer require phpoffice/phpexcel

你的代码应该是这样的

require 'vendor/autoload.php';

use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\Writer\Xls;

$spreadsheet = new Spreadsheet();
$sheet = $spreadsheet->getActiveSheet();
$range = range(65,90);

if(mysqli_num_rows($result) > 0)
{
   $sheet->setCellValue('A1', 'From');
   $sheet->setCellValue('B1', 'Department');
   $sheet->setCellValue('C1', 'Name of the task');
   $sheet->setCellValue('D1', 'Description');
   $sheet->setCellValue('E1', 'Priority:');
   $sheet->setCellValue('F1', 'Time elapsed');
   $sheet->setCellValue('G1', 'Notes:');

   // output data of each row
   while($row = $result->fetch_assoc()) 
   {
     // Do somme logic to store data to excell
   } 

   header('Content-Type: application/xls');
   header('Content-Disposition: attachment; filename=download.xls');
   $writer = new Xls($spreadsheet);
   $writer->save('php://stdout');
