background process in php

What do you mean by "update the movie"? And why would this process happen frequently?

As you use javascript it is never a problem to call a php script in the background. It is just the question what it is you need the php script to do and how you want it to output its data.

There are a lot of ways:
- use process.php?ext=.png, let the script first return a png and then have it do some maintainance processing.
- use a iframe and call the script in there.
- let javascript add a <script src="somephp.php"></script> to the document contents and let the script return javascript output.

Please give us more details as to what it is you need.

More details:  The movie is to seperated out into multiple modules.  The viewer has the option of watching it in its entirety or stopping at somepoint.  We need to keep track of which modules they have completed so that when they come back to the movie they can go right back to where they were.  So, once they reach the end of module 1 javascript kicks off a call to a php process (how does it do that?) that process runs in a seperate window (output something like you have finished module one continue to module 2?) if they click yes the javascript window goes away and the next module starts up, if they click no they go to another screen.  The part about going on to the next mod in the same screen is pretty key also.  Thanks for you time and whatever you can come up with in this mess ;-)
