【问题描述】：

我目前正在尝试从数据库中提取数据，然后使用 phpSpreadsheet 将其写入两个单独的工作表中。我遇到的问题是我无法下载多个文件，也找不到压缩它们的方法。

如何将这些电子表格保存到文件中并将其加载到 ZIP 中？下面显示了它是如何写入文件的：

function saveToFile($spreadsheet, $job_id) 
    $filename = $job_id.'_space_validation-'.'.xlsx';
    // Redirect output to a client's web browser (Xlsx)
    header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
    header('Content-Disposition: attachment;filename="'.$filename.'"');
    header('Cache-Control: max-age=0');
    // If you're serving to IE 9, then the following may be needed
    header('Cache-Control: max-age=1');

    // If you're serving to IE over SSL, then the following may be needed
    header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
    header('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT'); // always modified
    header('Cache-Control: cache, must-revalidate'); // HTTP/1.1
    header('Pragma: public'); // HTTP/1.

    writeToFile($spreadsheet);


function writeToFile($spreadsheet) 

    $writer = IOFactory::createWriter($spreadsheet, 'Xlsx');
    $writer->save('php://output');

编辑：我一直在查看函数“保存”的代码。这段代码对我来说有点高级，但据我所见，它创建了一个临时文件并将所有数据写入其中。我不知道怎么做，但我想如果我能得到这个临时文件，我也许可以把它发送到一个 zip 文件中。下面是这个函数的代码：

public function save($pFilename)

    if ($this->spreadSheet !== null) 
        // garbage collect
        $this->spreadSheet->garbageCollect();

        // If $pFilename is php://output or php://stdout, make it a temporary file...
        $originalFilename = $pFilename;
        if (strtolower($pFilename) == 'php://output' || strtolower($pFilename) == 'php://stdout') 
            $pFilename = @tempnam(File::sysGetTempDir(), 'phpxltmp');
            if ($pFilename == '') 
                $pFilename = $originalFilename;
            
        

        $saveDebugLog = Calculation::getInstance($this->spreadSheet)->getDebugLog()->getWriteDebugLog();
        Calculation::getInstance($this->spreadSheet)->getDebugLog()->setWriteDebugLog(false);
        $saveDateReturnType = Functions::getReturnDateType();
        Functions::setReturnDateType(Functions::RETURNDATE_EXCEL);

        // Create string lookup table
        $this->stringTable = [];
        for ($i = 0; $i < $this->spreadSheet->getSheetCount(); ++$i) 
            $this->stringTable = $this->getWriterPart('StringTable')->createStringTable($this->spreadSheet->getSheet($i), $this->stringTable);
        

        // Create styles dictionaries
        $this->styleHashTable->addFromSource($this->getWriterPart('Style')->allStyles($this->spreadSheet));
        $this->stylesConditionalHashTable->addFromSource($this->getWriterPart('Style')->allConditionalStyles($this->spreadSheet));
        $this->fillHashTable->addFromSource($this->getWriterPart('Style')->allFills($this->spreadSheet));
        $this->fontHashTable->addFromSource($this->getWriterPart('Style')->allFonts($this->spreadSheet));
        $this->bordersHashTable->addFromSource($this->getWriterPart('Style')->allBorders($this->spreadSheet));
        $this->numFmtHashTable->addFromSource($this->getWriterPart('Style')->allNumberFormats($this->spreadSheet));

        // Create drawing dictionary
        $this->drawingHashTable->addFromSource($this->getWriterPart('Drawing')->allDrawings($this->spreadSheet));

        $zip = new ZipArchive();

        if (file_exists($pFilename)) 
            unlink($pFilename);
        
        // Try opening the ZIP file
        if ($zip->open($pFilename, ZipArchive::OVERWRITE) !== true) 
            if ($zip->open($pFilename, ZipArchive::CREATE) !== true) 
                throw new WriterException('Could not open ' . $pFilename . ' for writing.');
            
        

        // Add [Content_Types].xml to ZIP file
        $zip->addFromString('[Content_Types].xml', $this->getWriterPart('ContentTypes')->writeContentTypes($this->spreadSheet, $this->includeCharts));

请帮忙！

【参考方案1】：

经过数小时的搜索，我找到了解决方案！

对于任何需要这个的人。我这样解决了我的问题：

        $writer = IOFactory::createWriter($spreadsheet, 'Xlsx');

        // Create a temporary file of and write our data to it
        $excel_file_tmp = tempnam("/tmp", 'tmp');
        $writer->save($excel_file_tmp);

        // Now zip the file and move the temporary file to it
        $zip_file_tmp = tempnam("/tmp", 'tmp');
        $zip = new ZipArchive();
        $zip->open($zip_file_tmp, ZipArchive::OVERWRITE);
        $zip->addFile($excel_file_tmp, $job_id.'-space_capture_data.xlsx');
        $zip->close();
