Question

我正在尝试使用PHPExcel将数据从我的数据库导出到Excel。我使用了this question中的代码。编辑mysql到mysqli并将扩展名更改为xlsx格式。但是，当我想打开文件时，我收到以下错误（我将其翻译成英文，如果不对，我很抱歉我的英文不好）

无法打开文件rapportage 29-05-2017.xlsx，因为文件格式或文件扩展名无效。检查文件是否已损坏，以及文件扩展名是否与文件格式匹配。

这是我复制和更改的代码：

<?php
require 'database.php';
require '../Classes/PHPExcel.php';

if (isset($_POST['exporteer'])) {

    $a = $_POST['organisatie_naam'];
    $b = $_POST['begin_datum'];
    $c = $_POST['eind_datum'];
    $datum = date("d-m-Y");

    $objPHPExcel = new PHPExcel();

    $query = "SELECT * FROM register WHERE organisatie_naam = '$a' AND (registratie_aansluit_datum BETWEEN '$b' AND '$c'";

    $result = mysqli_query($db, $query);

    $objPHPExcel = new PHPExcel();

    $rowCount = 1;

    while ($row = mysqli_fetch_array($result)) {
        $objPHPExcel->getActiveSheet()->setCellValue('A'.$rowCount, $row['registratie_id']);
        $objPHPExcel->getActiveSheet()->setCellValue('B'.$rowCount, $row['registratie_soort']);
        $objPHPExcel->getActiveSheet()->setCellValue('C'.$rowCount, $row['organisatie_naam']);
        $objPHPExcel->getActiveSheet()->setCellValue('D'.$rowCount, $row['apparaat_naam']);
        $objPHPExcel->getActiveSheet()->setCellValue('E'.$rowCount, $row['client_naam']);
        $objPHPExcel->getActiveSheet()->setCellValue('F'.$rowCount, $row['dienst_naam']);
        $objPHPExcel->getActiveSheet()->setCellValue('G'.$rowCount, $row['functie_naam']);
        $objPHPExcel->getActiveSheet()->setCellValue('H'.$rowCount, $row['kosten_soort']);
        $objPHPExcel->getActiveSheet()->setCellValue('I'.$rowCount, $row['status_naam']);
        $objPHPExcel->getActiveSheet()->setCellValue('J'.$rowCount, $row['registratie_aansluit_datum']);
        $objPHPExcel->getActiveSheet()->setCellValue('K'.$rowCount, $row['registratie_afsluit_datum']);
        $objPHPExcel->getActiveSheet()->setCellValue('L'.$rowCount, $row['registratie_omschr']);
        $rowCount++;
        pr($objPHPExcel);
    }

    header('Content-Type: application/vnd.openxmlformats-   officedocument.spreadsheetml.sheet');
    header('Content-Disposition: attachment;filename="rapportage ' . $datum . '.xlsx"');
    header('Cache-Control: max-age=0');

    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
    $objWriter->save('php://output');
    header("Location: ../rapportage.php");
}
?>

任何知道我是否可能遗漏某些东西的人？提前谢谢！

require('../phpexcel/PHPExcel.php');

require('../phpexcel/PHPExcel/Writer/Excel5.php');

$filename = 'userReport'; //your file name

$objPHPExcel = new PHPExcel();
/*********************Add column headings START**********************/
$objPHPExcel->setActiveSheetIndex(0)
            ->setCellValue('A1', 'username')
            ->setCellValue('B1', 'city_name');

/*********************Add data entries START**********************/
//get_result_array_from_class**You can replace your sql code with this line.

$result = $get_report_clas->get_user_report();

//set variable for count table fields.
$num_row = 1;
foreach ($result as $value) {
  $user_name = $value['username'];
  $c_code = $value['city_name'];
  $num_row++;
        $objPHPExcel->setActiveSheetIndex(0)
                ->setCellValue('A'.$num_row, $user_name )
                ->setCellValue('B'.$num_row, $c_code );
}

/*********************Autoresize column width depending upon contents START**********************/
foreach(range('A','B') as $columnID) {
    $objPHPExcel->getActiveSheet()->getColumnDimension($columnID)->setAutoSize(true);
}
$objPHPExcel->getActiveSheet()->getStyle('A1:B1')->getFont()->setBold(true);



//Make heading font bold
    /*********************Add color to heading START**********************/
    $objPHPExcel->getActiveSheet()
                ->getStyle('A1:B1')
                ->getFill()

                ->getStartColor()
                ->setARGB('99ff99');

    $objPHPExcel->getActiveSheet()->setTitle('userReport'); //give title to sheet
    $objPHPExcel->setActiveSheetIndex(0);
