Prevent session expired in PHP Session for inactive user

Question

I have a problem with my application: my application has many forms and need about 1 hour to finish this form because the form is dynamic (can add other forms). The problem

Answer 1

Instead of setting the time in ini to a fixed length, remind that session timeout is reset on reload. So create some ajax code that does a request every 5 minutes or so to a file (image or smth). This way the timer is reset every 5 minutes and users can spend a day filling out your forms.
