Creating zip files

Hi,

I am using the "pclziplibrary" to create a zip archive.
Now i have the following error message:
Error : PCLZIP_ERR_READ_OPEN_FAIL (-2) : Unable to open archive 'archive.zip' in wb mode

If someone is using the same library please tell me what this error means exactly. I am using the same code in my PC, it is working but not in the real server.

What i am able to do in my pc is writing the archive to the disc. Do you know if there is a way to create the archive just in memory and let the user download it without having to store it in the server?

Thank you

Has it ever worked on the server? You might need to check permissions
to see if your php script has access to write the zip archive to disc.

If you're using php5 you can use the ZipArchive[1] extension that is
built in now. It is quite fast and easy to use.

Does the file `archive.zip` exist where the script is looking for
it, and is it readable?

This has nothing to do with PHP itself. Check with the support
team for that project:

Hi,

Thank you for your answer. Now i figured out how to build the zip archive.
I am using a class that returns the compressed data:

$zipedresult = $zipfile->zipped_file();

This data, i can write it to a file. but i would like to make it downloadable without having to store it in the server. Is that possible?

Thanks

Yes. Now that you have the zip file contents, send the correct headers
to the browser for content-type and disposition, etc using header(),
then echo $zipedresult. I can never remember the header to send I have
to look it up most times.

So I searched for it again but didn't test:

$zipedresult = $zipfile->zipped_file();

header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-Disposition: attachment; filename=SomeFileName.zip");
header("Content-Type: application/zip");
header("Content-Transfer-Encoding: binary");

echo $zipedresult;
