Unless you create a copy of the file, then Apache will clean it up after your script has run (or at least it's supposed to, but sometimes /tmp becomes a little cluttered with crud) The best thing to do is to use move_uploaded_file to move the file to someplace, and give the file a new name (or keep the same one and add an extension if you want to ensure the file is given a unique name in the directory you're putting it into) There are lots of different scripts on the manual page for move_uploaded_file if you're feeling a little stuck. As a safety precaution, it's considered good practice to copy the file to a location outside of your document root. So if your document root is /var/www/html/ then maybe put the file in /var/www/user_files/ . This means that people can't use your website to upload their own scripts and gain access to your server, although it does mean you need to find an alternative way to serve up that file if you need, but that is quite easy, and there are lots of example scripts about for that if you need; many people on the list have written their own, and Tedd most likely has an example somewhere too!

The code is pretty simple. If the "simple script" the OP used did indeed move the file to the tmp directory, then it should be there for him to see. I suspect that: 1) the upload script is not working properly; 2) or the OP needs to refresh his IDE to reflect changes made to the server. Cheers, tedd -- ------- http://sperling.com/
