Symfony2 create and download zip file

I have one application that upload some files and then I can compress as zip file and download.

The export action:

public function exportAction() {
        $files = array();
        $em = $this->getDoctrine()->getManager();
        $doc = $em->getRepository('AdminDocumentBundle:Document')->findAll();
        foreach ($_POST as $p) {
            foreach ($doc as $d) {
                if ($d->getId() == $p) {
                    array_push($files, "../web/".$d->getWebPath());
                }
            }
        }
        $zip = new ZipArchive();
        $zipName = 'Documents-'.time().".zip";
        $zip->open($zipName,  ZipArchive::CREATE);
        foreach ($files as $f) {
            $zip->addFromString(basename($f),  file_get_contents($f)); 
        }

        $response = new Response();
    $response->setContent(readfile("../web/".$zipName));
    $response->headers->set('Content-Type', 'application/zip');
    $response->header('Content-disposition: attachment; filename=../web/"'.$zipName.'"');
    $response->header('Content-Length: ' . filesize("../web/" . $zipName));
    $response->readfile("../web/" . $zipName);
    return $response;
    }

everything is ok until the line header. and everytime I’m going here I got the error: “Warning: readfile(../web/Documents-1385648213.zip): failed to open stream: No such file or directory”

What is wrong?

and why when I upload the files, this files have root permissions, and the same happens for the zip file that I create.

Answer

solved:

$zip->close();
header('Content-Type', 'application/zip');
header('Content-disposition: attachment; filename="' . $zipName . '"');
header('Content-Length: ' . filesize($zipName));
readfile($zipName);

apparently closing the file is important 😉
