Is there anything like ZipArchive but for sending the zip for download without generating the file on disk?

Question

I want to create a zip file in PHP and use the header() function to make it downloadable without having to save the file on the server. But I think the built in ZipArchive can't do this. I found a few that can, but they all add files from existing files, and I need to add it like ZipArchive::addFromString() does.

Does someone knows a class or something with this capabilities?

Answer 1

gzip does it for a file. and for an archive you can use gzip and tar as follows.

tar -cz  thedir 

this is how to do it with zip.

zip - file1.txt file2.txt

Answer 2

According to the PHP compression streams documentation ZipArchive registers the zip:// stream wrapper. While I never worked with zip:// streams you could check out if zip.compress works. You can build a test from another example found here .
