PHPSpreadsheet - как мне создать zip-файл из PHPSpreadsheet?

/ 25 февраля 2019

В настоящее время я пытаюсь извлечь данные из базы данных, в которую они затем записываются на два отдельных листа с использованием PHPSpreadsheet.Проблема в том, что я не могу загрузить несколько файлов и не могу найти способ их заархивировать.

Как я могу сохранить эти таблицы в файл и загрузить их в ZIP-архив??Ниже показано, как это записывается в файл: 

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');
}

EDIT : я просматривал код для функции «сохранить».Этот код немного продвинут для меня, но из того, что я вижу, он создает временный файл и записывает в него все данные.Я не знаю как, но я полагаю, что если я смогу получить этот временный файл, я смогу отправить его в zip-файл.Вот код ниже для этой функции: 

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));

        $this->numFmtHashTable->addFromSource($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));

        //if hasMacros, add the vbaProject.bin file, Certificate file(if exists)

ПОСЛЕ МНОГИХ ЧАСОВ ПОИСКА Я НАШЕЛ РЕШЕНИЕ ДЛЯ ЭТОГО!

Для любого из вас, кому это нужно ... Я решил свою проблему следующим образом: 

        $writer = IOFactory::createWriter($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();
