exec() in background
How can I execute an external program and let it run in the background, rather than waiting for it to finish before the page is "done"?

I'm pretty sure the method you are talking about is called 'forking'. In unix you can usually run most commands in the background, simply execute the program using the standard unix syntax between backticks (`) with the necessary flags to run it in the background and that should work...
Actually... I've just done a bit more research. It would appear that to make a process run in the background you just put an ampersand (&) at the end of the line.
so your script could look like:
<?php`process_name &`;
?>
