删除临时文件php

Question

I have a page that which add new User.

The user have file attachment option.

I created a temporary table and directory to upload file and track the user data.

The problem is the user is not yet added ,so i cannot save these files under the contact.

what i am doing is saving the files and tracking using a temp table and once the user is added moving those files under that user.

Assume that user uploaded the files and closed the page without adding user.

Then how can i delete the temp files and table values ?

can i use the browser close event ? alternatively is there anyway to do this in php [because i am new in php] ?

I am using Codeignitor - it will be very helpful if i get answer respective to CI.

Thanks in advance.

Answer 1

Browser close events are highly unreliable. When you add the user to the temp table, add a timestamp as well. Run a nightly cron job that prunes all old values from the DB and files from the filesystem.
