upload_tmp_dir cleanup

Hi,

I have not set the "upload_tmp_dir" in my php.ini, so I am assuming it
is using /tmp/.

From time to time, I noticed that some strange files appear in the /
tmp, and when I viewed it, I believe it is the temp file which somehow
not handled correctly by my scripts and leave in the /tmp/ folder.

I want to ask, will PHP delete the files under this folder from time
to time automatically? Or should I setup a cron to clean up?

Thanks.

Probably.
You can simply test however: Just spit out the $_FILES array from you
uploadscript.
It contains the path to the uploaded file (which gets a strange random
name during the process, but you should be able to see the path.)
echo "<pre>";
print_r($_FILES);
echo "</pre>";

Look for: ['tmp_name']

No, unless you create a file in the tempdir yourself.
PHP cleans up the uploaded file when the script ends.

Lots of processes on your server could be using the temp dir.
Setting up a cronjob that cleans up the old files in the tempdir (eg
older than a day) is always a good idea. :-)
