多个表到单个 PHP 电子表格

Question

我正在填充许多表格，其中包含特定年份每月的车辆里程详细信息。我已经设法填充表格并在网页上输出结果，但我被困在如何将 HTML 网页上显示的确切表格转换为电子表格，对于我使用 PHPSpreadsheet 库的 excel 生成。

从数据库中填充数据的 HTML 表格如下所示，

HTML页面中显示的这个表格只是为了我的开发目的，但实际要求是生成excel表格报告。我如何通过一次将报告生成到一个 phpspreadsheet 中来实现这一点。

从数据库中取出数据并输出到表中的代码如下，

<?php
if (isset($_POST['btnreport'])) {
$querymain = "SELECT * FROM users";
$resultsmain = mysqli_query($connect,$querymain);
if ($resultsmain->num_rows>0) {
    while ($userid = mysqli_fetch_assoc($resultsmain)) {
        $approvedkm = $userid['approved_kmpl'];
        ?>
        <table class="table" class="mt-3 mb-3">
        <thead class="bg-dark text-light">
        <tr>
        <th colspan="3"><?php echo $userid['company']; ?></th>
        <th colspan="3"><?php echo $userid['name']; ?></th>
        <th colspan="3"><?php echo $userid['approved_kmpl'];?> KM</th>
        </tr>
        </thead>
        <thead>
        <tr>

您可以通过this library 轻松完成。

下载this class 并将其另存为php-export-data.class.php 在您拥有此导出脚本的同一文件夹中。

下面的脚本会直接下载文件。

<?php

// When executed in a browser, this script will prompt for download 
// of 'test.xls' which can then be opened by Excel or OpenOffice.

require 'php-export-data.class.php';

// 'browser' tells the library to stream the data directly to the browser.
// other options are 'file' or 'string'
// 'test.xls' is the filename that the browser will use when attempting to 
// save the download
$exporter = new ExportDataExcel('browser', 'test.xls');

$exporter->initialize(); // starts streaming data to web browser


$month = 'Month';
$mileage = 'Daily Mileage';
$usage = 'Usage For Month';
$required = 'Required Per Month';
$excess = 'Excess Used';
$percentage = '(%)';
$kmpl = 'KM/L';
$consumed = 'Consumed Liters';
$cost = 'Cost';

// Creating Heaer Row
$row = array( 
        $month,
        $mileage,
        $usage,
        $required,
        $excess,
        $percentage,
        $kmpl,
        $consumed,
        $cost
);

$exporter->addRow($row); 

// Inside your while loop ()
 
while(.....) {
     .......
     .......
    // Build a row from variables
    $row = array( 
        $month,
        $mileage,
        $usage,
        $required,
        $excess,
        $percentage,
        $kmpl,
        $consumed,
        $cost
    );
    $exporter->addRow($row); 
}



// pass addRow() an array and it converts it to Excel XML format and sends 
// it to the browser
$exporter->addRow($row); 
 

$exporter->finalize(); // writes the footer, flushes remaining data to browser.

exit(); // all done

?>
