Launching an independent process from php (via httpd)

[Roe]

i'm trying to spawn a daemon-like process from php on a unix environment, keep the pid for reference and keep it completely independent from httpd processes. This is useful for controlling middleware applications from administrative backoffices. I want to keep it generalized to reuse for any command, i don't want to write a .sh for every command.using php's exec() i'm running this command:\[code\]$command = "java /myApp/TestInfiniteLoop";$log = "/myApp/myLog.txt";$echos = null;$fullCommand = "bash -c 'nohup $command < /dev/null > $log 2>&1 & echo $! & exit' & echo $!";exec($fullCommand, $echos);$pid = (int)$echos[0] + 2;\[/code\]It returns $pid but does not spawn process (or kills it immediately...).If i run the $fullCommand on a bash shell it works perfectly. I can close the bash and everything keeps running as expected.If i take out the "nohup " it works (but pid is +1 and not +2), but as soon as you stop httpd the process get's killed too...[*]What is the correct way to make it work? [*]If possible can anyone correct it to get the pid directly? i'm assuming it is the second process from the bash (+2) call, but it is possible (though not probable, i know...) that it wouldn't be the same.PS: i've been testing it on Mac and Linux environments.
