Do you mean "...to essentially run the PERL script in the background..."
If so you can just use the info in the manual: function.exec.html:
"Note: If you start a program using this function and want to leave it running in the background, you have to make sure that the output of that program is redirected to a file or some other output stream or else PHP will hang until the execution of the program ends. "
i.e.
<?php
...
exec("/my/perlscript >> /my/dump.txt 2>&1");
...
?>This will have your PHP script continuing without waiting for the perl script.

AFAIK there's no way to do this. When the request ends (user hits stop, exit or die called) the process is ended. This includes children. If you could set it off asynchronously, there would be no way of knowing when it ended as the process wouldn't have access to that session any more.
I would suggest setting a value in a table and have a cron job check for those values, run the script if it's supposed to, then update the table with the results. Then the PHP script can check the table to see it it's done.
