Hi all
was wondering if it would be possible to automatically invoke a PHP script after the user has been at a page for a particular amount of time.

Here what i wanna do:
1. The user is filling out a form on a PHP page
2. After a certain amount of time (say 10 mins) the submit button is invoked.
3. Another script processes the form data (whatever has been entered in that time limit)

Any tips/suggestion??
