Download large file

Either set up some static files/ folder to where you generate your zip files, then just propagate that url as the download link.

Or use PHP's fpasshtru()

I can't have this zip archive availible for everyone, there are some confidential data in there so I have to check for permissions before I can send it to the user. I tried the fpassthru() but it did not solve the issue.

class DownloadController extends PhController {
    public function indexAction() {
        $this->view->disable();
        $filePath = 'some/protected/file.zip';
        $this->response->setFileToSend($filePath, 'download_name.zip');
        $this->response->send();
    }
}

I have already tried this approach before, the issue is that even tho it starts to download, the process of downloading is always interrupted at exactly 65 MB.

EDIT: When I tried to download the same file by using simple plain php script in public directory, I was able to download the whole file without any problem, but when I download it using an controller action, it will die at 65 MB. https://i.imgur.com/YsAHd7O.png

Weird... what if you put that plain PHP code into a controller action?

class DownloadController extends PhController {
    public function indexAction() {
        $this->view->disable();
        $filePath = 'some/protected/file.zip';
        $fileName = basename($path);

        $finfo = finfo_open(FILEINFO_MIME_TYPE);
        $mime = finfo_file($finfo, $filePath);

        header("Content-Disposition: attachment; filename=$fileName;");
        header("Content-Type: $mime");
        header('Content-Length: ' . filesize($path));
        $fh = fopen($filePath, 'rb');
        fpassthru($fh);
        fclose(fh);
        exit;
    }
}

Same thing, interrupt at 65 MB because of exceeded memory:

    public function archiveDownloadFileAction() {
        $this->view->disable();
        $filePath = "path/to/the/file";

        header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
        header('Content-Description: File Transfer');
        header('Content-type: application/zip');
        header('Content-Disposition: attachment; filename="filename.zip"');

        readfile($filePath);
        die();
    }

You can also have a look at xsendfile for apache or nginx

I have tried that already with no success.

This finally helped, thank you very much!

There's something wrong in your setup, fpassthru streams the file handle directly to the output, the memory footprint should be minimal.

Try clearing the output buffer:

class DownloadController extends PhController {
   public function indexAction() {
       $this->view->disable();
      ob_get_clean();
      ob_end_flush();

       $filePath = 'some/protected/file.zip';
       $fileName = basename($path);

       $finfo = finfo_open(FILEINFO_MIME_TYPE);
       $mime = finfo_file($finfo, $filePath);

       header("Content-Disposition: attachment; filename=$fileName;");
       header("Content-Type: $mime");
       header('Content-Length: ' . filesize($path));
       $fh = fopen($filePath, 'rb');
       fpassthru($fh);
       fclose($fh);
       exit;
   }
}
