Question

我正在尝试将我的数据导出到电子表格，并且它在我的localhost中工作正常，但是当我将其上传到服务器时，它总是下载具有不可读内容的文件。在这里编写代码。

我的服务器中已经安装了php_xml，php_zip和gd。下载的文件是只读的。

    error_reporting(E_ALL);
    ini_set('display_errors', TRUE);
    ini_set('display_startup_errors', TRUE);
    date_default_timezone_set('Europe/London');

    if (PHP_SAPI == 'cli')
        die('This example should only be run from a Web Browser');

    /** Include PHPExcel */
    require_once dirname(__FILE__) . '/lib/PHPExcel.php';


    // Create new PHPExcel object
    $objPHPExcel = new PHPExcel();

    // Set document properties
    $objPHPExcel->getProperties()->setCreator("test")
                         ->setLastModifiedBy("test")
                         ->setTitle("test Report")
                         ->setSubject("test Report")
                         ->setDescription("test Report")
                         ->setKeywords("test Report")
                         ->setCategory("test Report");

    //Title
    $objPHPExcel->getActiveSheet()->mergeCells('A1:J1');
    $objPHPExcel->getActiveSheet()->getStyle('A1:J1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
    $objPHPExcel->getActiveSheet()->getStyle("A1:J1")->getFont()->setSize(20);
    $styleArray = array(
        'font' => array(
            'bold' => true
        )
    );
    $objPHPExcel->getActiveSheet()->getStyle('A1:J1')->applyFromArray($styleArray);
    $objPHPExcel->setActiveSheetIndex(0)
        ->setCellValue('A1', 'test Report');
    $objPHPExcel->getActiveSheet()->getRowDimension(1)->setRowHeight(30);
    // //Set Column headlines

  $objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(15);

  $objPHPExcel->getActiveSheet()->getColumnDimension('H')->setWidth(15);
  $objPHPExcel->getActiveSheet()->getColumnDimension('I')->setWidth(18);
  $objPHPExcel->getActiveSheet()->getColumnDimension('J')->setWidth(15);

$colArray=array("A","B","C","D","E","F","G","H","I","J");
 $rowNumber = 3; 
    while ($row = mysqli_fetch_row($result)) { 
    $col = 0; 
    foreach($row as $cell) {

        $objPHPExcel->getActiveSheet()->getStyle($colArray[$col].$rowNumber)->getFont()->setSize(10);
        $col++; 
    } 
    $rowNumber++; 

    } 
// Rename worksheet
$objPHPExcel->getActiveSheet()->setTitle('test Report');

Answer 1

我真的没有看到你的核心逻辑有问题。我能够通过轻微的修改从我的linux盒子中生成有效的xlsx文件

更新了require_once行，如下所示（我觉得保持PHPExcel默认文件夹结构完好无损）

require_once dirname（ FILE ）。 '/../类/ PHPExcel / IOFactory.php';

由于我没有与示例对应的Mysqli，我将其修改为..

$ row = array（1,2,3,4,5,6,7,8,9）;
// while（$ row = mysqli_fetch_row（$ result））{

总的来说，我想，您需要查看mysqli数据是否有效并正确启动PHPExcel。除此之外，我在这里看不到任何问题。

我在开始文档生成之前使用 ob_start（），然后以 ob_end_clean（）结束，这解决了我的问题。
