Generating and downloading an excel file generates a ERR_INVALID_RESPONSE

Solution 1

Eventually the issue was in the ZipArchive class, that's why it worked on one server and didn't work on the other.

More documentation here: http://www.php.net/manual/en/zip.installation.php

Solution 2

I had the same problem. Check with "php -m" It gives you a list of modules and check if You have the "zip" module installed. http://php.net/manual/en/book.zip.php

This module is needed for PhpExcel. If you don´t have it, try to install or change your php version. In my case I solved changing my php from 7 to php 5.5

Solution 3

You can try saving to temp file and serving it with the redirect instead:

$objWriter->save('wwwroot/some-file.xlsx');
header("Location: /some-file.xlsx");
exit();

    This is my code:

     public function downloadexcel($requestId) {
        $this->loadModel('MaterialsRequest');
        $materialsRequests = $this->MaterialsRequest->find('all', array('conditions' => array('MaterialsRequest.request_id' => $requestId)));
        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__) . '/../Classes/PHPExcel.php';
        // Create new PHPExcel object
        $objPHPExcel = new PHPExcel();
    
        // Set document properties
        $objPHPExcel->getProperties()->setCreator("mez")
                ->setLastModifiedBy("mez")
                ->setTitle("Supply Template")
                ->setSubject("Supply Template")
                ->setDescription("Supply Template , please fill and upload.")
                ->setKeywords("office 2007 openxml php")
                ->setCategory("Supply");
    
    
    
    
        $objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(10);
        $objPHPExcel->getActiveSheet()->getColumnDimension('B')->setWidth(40);
        $objPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth(30);
        $objPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(30);
        $objPHPExcel->getActiveSheet()->getStyle('A')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_LEFT);
        $objPHPExcel->getActiveSheet()->getStyle('B')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::VERTICAL_CENTER);
        $objPHPExcel->getActiveSheet()->getStyle('C')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::VERTICAL_CENTER);
        $objPHPExcel->getActiveSheet()->getStyle('D')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::VERTICAL_CENTER);
    
        // Add some data
        $objPHPExcel->setActiveSheetIndex(0)
                ->setCellValue('A1', 'Material ID')
                ->setCellValue('B1', 'Material Name')
                ->setCellValue('C1', 'Quantity')
                ->setCellValue('D1', 'Your offer');
    
    
        $index = 2;
        foreach ($materialsRequests as $oneMaterialsRequests) {
    
            $objPHPExcel->setActiveSheetIndex(0)
                    ->setCellValue('A' . $index, $oneMaterialsRequests['MaterialsRequest']['material_id'])
                    ->setCellValue('B' . $index, $oneMaterialsRequests['Material']['name'])
                    ->setCellValue('C' . $index, $oneMaterialsRequests['MaterialsRequest']['qty'])
                    ->setCellValue('E' . $index, $oneMaterialsRequests['MaterialsRequest']['id']);
    
    
            $index++;
        }
    
        /// Set sheet security
        $MaterialsRequestsNo = count($materialsRequests);
        $MaterialsRequestsNo+=1; //add count for header
        $objPHPExcel->getActiveSheet()->getProtection()->setSheet(true);
        $objPHPExcel->getActiveSheet()
                ->getStyle('D2:D' . $MaterialsRequestsNo)
                ->getProtection()->setLocked(
                PHPExcel_Style_Protection::PROTECTION_UNPROTECTED
        );
    
    
        // Miscellaneous glyphs, UTF-8
        // Rename worksheet
        $objPHPExcel->getActiveSheet()->setTitle('Supply');
    
    
        // Set active sheet index to the first sheet, so Excel opens this as the first sheet
        $objPHPExcel->setActiveSheetIndex(0);
    
    
        // Redirect output to a client’s web browser (Excel2007)
        header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
        header('Content-Disposition: attachment;filename="Supply.xlsx"');
        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/1.0
    
        $objWriter=PHPExcel_IOFactory::createWriter($objPHPExcel,'Excel2007');
        $objWriter->save('php://output');
    
        exit;
    }
    

    From my local server operating on lamp when I call this function I can get the excel sheet and the web page would close after I call the function, when I'm calling it however on my apache server it brings out the error: ERR_INVALID_RESPONSE, I went through the code putting a die(); after each line to see how it would respond and up until putting a die() after $objWriter=PHPExcel_IOFactory::createWriter($objPHPExcel,'Excel2007'); it would download the spreadsheet but it would be corrupted and wouldn't close the page and it wouldn't bring up that error message, however apparently $objWriter->save('php://output'); is causing the error to come up, the page would freeze and the excel file wouldn't get downloaded.

    I debugging someone else's code but I can't figure this part out.
