Is it possible to also use this if our files are stored on S3?

Just like the title says, would like to be able to add files to the archive that are not stored on the server.

In that case you need to copy them to your server first. This is just a wrapper around the native php zip commands

@Chumper @mcblum Couldn't you open a file stream and then use the addString-method?

[raz-iacob]

That is what I did.

How can I use this on a Flexible Environment of Google App Engine which prefers Google Cloud Storage rather than File System?
