If you want to execute some code after your php page has been returned to the user. Try something like this - <?php function index() { function shutdown() { posix_kill(posix_getpid(), SIGHUP); } // Do some initial processing echo("Hello World"); // Switch over to daemon mode. if ($pid = pcntl_fork()) return; // Parent ob_end_clean(); // Discard the output buffer and close fclose(STDIN); // Close all of the standard fclose(STDOUT); // file descriptors as we fclose(STDERR); // are running as a daemon. register_shutdown_function('shutdown'); if (posix_setsid() < 0) return; if ($pid = pcntl_fork()) return; // Parent // Now running as a daemon. This process will even survive // an apachectl stop. sleep(10); $fp = fopen("/tmp/sdf123", "w"); fprintf($fp, "PID = %s\n", posix_getpid()); fclose($fp); return; } ?> --was-- If you want to execute some code after your php page has been returned to the user.
