Should your upload fail for any reason you've got a half processed file that is non-recoverable. No do-overs. If you stick to the standard processes with out the extension, Upload Save somewhere (or leave in temp upload folder) Process Send result back to user Unlink file Generating the file and sending it to the user is also pretty standard Create your dataset Send appropriate headers Send data Close connection For this, there usually isn't a need to save the file. You may run into issues streaming the data to certain browsers. Also one of the main downsides to your upload is high load situations or large file situations (where file size exceeds php's upload limit). My personal preference is to save that file to disk so that if needed I can work with it later ( if say the server load is high) and email the results to the user. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
