PHPExcel保存CSV也是在添加网页HTML

2022-11-06 08:40:30

我有一个网页,其中有一个广播组作为您要保存的文件格式的选项.选项包括：

> .xls
> .xlsx
> .csv

所有工作,但.csv,因为它也将页面HTML添加到文件的底部.

这是我正在尝试的(代码片段显示功能)：

// Creating the format
$data = $this->getQueryResults();

$objPHPExcel = new PHPExcel();
$objPHPExcel->getActiveSheet()->setTitle("Report"); 

$objPHPExcel->getProperties()->setCreator("me");     
$objPHPExcel->getProperties()->setLastModifiedBy("me");                 
$objPHPExcel->getProperties()->setSubject("Report Stuff");     
$objPHPExcel->getProperties()->setDescription("Report Stuff");

// Next I iterate through the data array
$objPHPExcel->getActiveSheet()->setCellValue($col.$rowNumber,$cell);
$objPHPExcel->getActiveSheet()->getColumnDimension($col)->setAutoSize(true);

// check the radio option selected for the file format
if($this->radioXLS->Checked) {
    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');

    header('Content-Type: application/vnd.ms-excel');
    header('Content-Disposition: attachment;filename="'.$excel_name.'.xls"');
    header('Cache-Control: max-age=0');
}

if($this->radioXLSX->Checked) {
    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');

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

if($this->radioCSV->Checked) {
    ob_end_clean(); // add/removing this does nothing
    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'CSV');
    $objWriter->setDelimiter(',');
    $objWriter->setEnclosure('');
    $objWriter->setLineEnding("\r\n");
    $objWriter->setSheetIndex(0);
    ob_end_clean(); // add/removing this does nothing

    header('Content-Type: text/csv');
    header('Content-Disposition: attachment;filename="'.$excel_name.'.csv"');
    header('Cache-Control: max-age=0');
}

$objWriter->save('php://output');

有关为什么将页面HTML附加到.csv文件的任何想法？

另外,如果重要的话,这是普拉多项目

更新：

再来一点…

我有一个网页,以表格格式(Think table / grid)生成报告.在同一页面上,我可以选择将表格格式的日期保存到Excel .xls(不知何故.xlsx现在不工作了,呃…).用户可以选择将文件保存在.xls .xlsx .csv中,当单击该文件从该页面下载时.

这是否会导致已经呈现的网页通过以下方式添加到输出：php：// output？

更新 – 解决方案：

在查看excel文件之后,它还添加了网页HTML.我也查看了输出缓冲区的PHP函数,但仍然没有任何工作

    while(ob_get_level() > 0) {
        ob_end_clean();
    }

    if($this->radioCSV->Checked) {                        
        header('Content-Type: text/csv');
        header('Content-Disposition: attachment;filename="'.$excel_name.'.csv"');
        header('Cache-Control: max-age=0');

        $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'CSV');
        $objWriter->setDelimiter(',');
        $objWriter->setEnclosure('');
        $objWriter->setLineEnding("\r\n");
        $objWriter->setSheetIndex(0);
    } elseif($this->radioXLSX->Checked) {
        header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
        header("Cache-Control: no-store, no-cache, must-revalidate");
        header("Cache-Control: post-check=0, pre-check=0", false);
        header("Pragma: no-cache");
        header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
        header('Content-Disposition: attachment;filename="'.$excel_name.'.xlsx"');
        header('Cache-Control: max-age=0');

        $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
    } else {
        header('Content-Type: application/vnd.ms-excel');
        header('Content-Disposition: attachment;filename="'.$excel_name.'.xls"');
        header('Cache-Control: max-age=0');

        $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
    } 

    $objWriter->save('php://output');
    exit();

解决方法:

写入php：//输出与执行普通echo语句完全相同. $objWriter-> save()的输出将被添加到回显或位于PHP块之外的所有其他内容(<？php ...？>).

一个例子：

>这是对的：

<?php

$objPHPExcel = new PHPExcel();
$objPHPExcel->getActiveSheet()->setTitle("Report"); 
// ...
$objWriter->save('php://output');

?>

>这是错的：

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<?php

echo '<h1>Export to Excel</h1>';

$objPHPExcel = new PHPExcel();
$objPHPExcel->getActiveSheet()->setTitle("Report"); 
// ...
$objWriter->save('php://output');

?>
</body>
</html>
