The second argument to writeToFileHandle is supposed to address that: writeToFileHandle( $fileHandle [, $seekable] ) Write a zip archive to a file handle. Return AZ_OK on success. The optional second arg tells whether or not to try to seek backwards to re-write headers. ... If you pass a file handle that is not seekable (like if you're writing to a pipe or a socket), pass a false second argument: ...
