Processing previously uploaded files with subsequent removal

Problem: When filling out the form I need to be able to upload multiple files and after it when I submit the form to make the processing of all downloaded files.

On the client side to asynchronous file uploading I use a hidden iframe (because of IE7 support requirement). After successfully file upload I add information about this file to the form (its $_FILES["file"]["name"] and $_FILES["application_add_file"]["tmp_name"]).

When the form is submited I recieve array of the files like:

files[0][file_path]:/tmp/phpR8eHLx
files[1][file_path]:/tmp/phpDVh3Aw

How can I get these files for processing?

I tried file_get_contents($_POST['files'][0]['file_path']) but it's expected returns an error

Warning: file_get_contents(/tmp/phpR8eHLx): failed to open stream: No such file or directory

I know that I can use move_uploaded_file() on each file upload, but if I do so how I can handle situation when user upload some files but do not submit the form? As I understand those uploaded files will remain on my server and I need to somehow remove them manually (and as i guess in the tmp directory files deleted after a while automatically).

Update: I dynamically add <input type="file"> to the form and submit all files at once. I want to convert uploaded files to base64 and send it to another server. Should I use move_uploaded_file() (for safety reasons?) or I can just work with it in a tmp dir?

You will have to move_uploaded_file() on each file upload, store those in an upload directory and wait for the form submit.

Then you can set up a cron job on the server to monitor the old files, so if some user doesn't submit the form, the job will clean it up after a predefined time.

I also suggest that you don't send the server path of these files back to the client, instead you can store them server side, either on Session or in the Database.
