Question

因为很难在不同浏览器之间处理不同的标准，所以我放弃尝试使用js或jQuery导出html表。我想知道我是否可以将html中的表重新发送回服务器并在服务器上生成.xls文件供用户下载。

现在在服务器端使用PHPExcel，我的代码是这样的：

$filename = "DownloadReport";
$table = $_POST['table'];

ini_set('zlib.output_compression','Off'); 
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
//the folowing two lines make sure it is saved as a xls file
header('Content-type: application/vnd.ms-excel');
header('Content-Disposition: attachment; filename='.$filename);

$objReader = PHPExcel_IOFactory::createReader('HTML');
$objPHPExcel = $objReader->load($table);

$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save('php://output');

exit;

问题是我无法直接加载html表。我该如何处理？

还有一个问题是，当我在php中设置标题时，单击按钮时文件不会下载。实际上，我可以查看POST响应的Header的所有属性，以及响应的内容（在FireBug中），这些都是正确的。

要将内容直接放入$objPHPExcel，您需要创建一个工作表，然后逐个单元格设置值，这不是您想要的。

要插入整个HTML表格，您必须从HTMLReader

中阅读

在下面的代码中，Writer将用于将内容输出到文件

$filename = "DownloadReport";
$table    = $_POST['table'];

// save $table inside temporary file that will be deleted later
$tmpfile = tempnam(sys_get_temp_dir(), 'html');
file_put_contents($tmpfile, $table);

// insert $table into $objPHPExcel's Active Sheet through $excelHTMLReader
$objPHPExcel     = new PHPExcel();
$excelHTMLReader = PHPExcel_IOFactory::createReader('HTML');
$excelHTMLReader->loadIntoExisting($tmpfile, $objPHPExcel);
$objPHPExcel->getActiveSheet()->setTitle('any name you want'); // Change sheet's title if you want

unlink($tmpfile); // delete temporary file because it isn't needed anymore

header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'); // header for .xlxs file
header('Content-Disposition: attachment;filename='.$filename); // specify the download file name
header('Cache-Control: max-age=0');

// Creates a writer to output the $objPHPExcel's content
$writer = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$writer->save('php://output');
exit;

html表在2张或以上：

    require_once "/PHPExcel.php";
    $objPHPExcel = new PHPExcel();
    $objPHPExcel->setActiveSheetIndex(0);
    $asheet = $objPHPExcel->getActiveSheet();

    $table = '<table></table>'; //put your table

    $tmpfile = tempnam(sys_get_temp_dir(), 'html');
    file_put_contents($tmpfile, $table);
    $excelHTMLReader = PHPExcel_IOFactory::createReader('HTML');
    $excelHTMLReader->loadIntoExisting($tmpfile, $objPHPExcel);
    unlink($tmpfile);

    // sheet 2
    $objPHPExcel2 = new PHPExcel();
    $objPHPExcel2->setActiveSheetIndex(0);
    $asheet2 = $objPHPExcel2->getActiveSheet();

    $table2 = '<table></table>'; //put your another table

    $tmpfile2 = tempnam(sys_get_temp_dir(), 'html');
    file_put_contents($tmpfile2, $table2);
    $excelHTMLReader2 = PHPExcel_IOFactory::createReader('HTML');
    $excelHTMLReader2->loadIntoExisting($tmpfile2, $objPHPExcel2);
    unlink($tmpfile2);

    //$objPHPExcel->addSheet($asheet2, 0);
    $objPHPExcel->addExternalSheet($asheet2, 0); //copy sheet2 in first objPHPExcel

    header("Content-Type:application/vnd.ms-excel");
    header("Content-Disposition:attachment;filename=simple.xls");

    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
    $objWriter->save('php://output');
