Hi spiffen

Thanks for your nice reply.

I tried your program. It starts download,but arguments are not correctly passed to function. i.e., the zip file is blank. It don't have no files. I checked the path of given files even it's not working. Can you try it for me and send me the feedback. I eagerly waiting for your reply.

Cheers

Oh man. I totally forgot about this topic. :)
Well.. To the question. My example was based on having the files to be zipped in the same directory as the .php doing the exec().. And yes. It worked for me..

You could try to experiment further on with using full path to each file that should be included in the zip.

.. And correct me if Im wrong. But you should have solved the problem by now since it was 2 months ago.. :)

Well.. Sorry about forgetting the topic.
Good luck.

/Regards Spiffen.
