Dit is van: http://nl2.php.net/exec.
Volgens mij is dat toch wat je zoekt?

Here's a function to launch a low-priority background process very
simply, returning control to the foreground.  I found that a lot of the
other approaches shown here allow the script to continue running, and
the page is served up to the user, but the PHP thread that launched the
process cannot be re-used until the process has completed.  Stdout and
stderr need to be redirected to /dev/null to prevent this.

This is for BSD/*NIX servers only (tested on Fedora Core and OSX).
Win32 approaches would be necessarily very different.  Omit 'nice' if
you don't want to run the process with lowered priority.

<?php
function fork($shellCmd) {
   exec("nice $shellCmd > /dev/null 2>&1 &");
}
?>
