I agree that there should be some error indication (not sure if ER_OPEN would be appropriate when creating a file, though) instead of returning TRUE. Did you get any warning/notice in the error log (presuming that you have error_reporting set to an appropriate value for development)? Also, maybe the error is reported only when ->close() is called. It might be worthwhile to check its return value. Unfortunately, I can't easily try it myself because I'm on Windows 7 Home, where I do not easily have access to the ACL (it was possible with XP, but I had to reboot into safe mode; don't know if that's possible with Win7). Maybe you want to spend some further time on the issue and file a respective bug report[1] if appropriate. > I ran across user comments on the php.net site for ZipArchive claiming that > > addEmptyDir was remove or disabled, and in fact I couldn't get it to work. I just tried that with PHP 5.4.19, and it worked fine. I can imagine, though, that empty directories might not be displayed by all zip readers, and actually I'm not sure if zip archives do store directories at all; quite likely only files are stored. Anyhow, the issue seems to demand further investigation. It seems there are no respective reports in the PHP bug tracker.[2] > I also discovered that calling download code from an async get request > wouldn't > > work.

If you use XMLHttpRequest (or a wrapper) to request a download, the response can be received, but it can't be stored in the file system of the client due to security considerations. > Thanks for time and attention: You're welcome.
