使用php下载zip文件夹

Question

I am trying to download zip folder.

Here is my code

header('Content-Type: application/zip');
header('Content-disposition: attachment; filename=filename.zip');
header('Content-Length: ' . filesize($zipfilename));

  $files = array('../upload/ES:AIJ_168/M:MSW.doc','../upload/ES:AIJ_168/M:MSW.pdf');



$zipname = 'file.zip';
$zip = new ZipArchive;
$zip->open($zipname, ZipArchive::CREATE);
foreach ($files as $file) {
  $zip->addFile($file);
}
$zip->close();

readfile($zipname);
?>

But When I am running this script.It downloads just one empty upload folder. I don't know why this happens.Please anyone help me out.

Answer 1

I saw three points in your question

1) You're sending the content length before the file creation

2) When you are fetching the file size you are using $zipfilename, but when you open the zip file for adding files you are using $zipname.

3) You are using colon (:) in the file names. I'm not sure about this use on unix, but you can't name a file with colon on windows.

I believe that the code will be like this:

header('Content-Type: application/zip');
header('Content-disposition: attachment; filename=filename.zip');    

$files = array('../upload/ES-AIJ_168/M-MSW.doc','../upload/ES-AIJ_168/M-MSW.pdf');

$zipname = 'file.zip';
$zip = new ZipArchive;
$zip->open($zipname, ZipArchive::CREATE);
foreach ($files as $file) {
    $zip->addFile($file);
}
$zip->close();
header('Content-Length: ' . filesize($zipname));
readfile($zipname);

PS.: I've used minus signs (-) instead of colons in the file names
