There are a number of ways to do this, including (1) setting up
the process to be created as a cron job[1], run by cron independently;
(2) using a combination of exec('command &')[2] and
ignore_user_abort(1)[3] functions to force a command to daemonize and
continue running until completes; (3) work out a routine to use
process control[4]. All of these presume a *NIX system, of course.
