Joe,

how would you do that, given the example application above? I see no way of getting exit status from a process which has finished.

function is_process_running($PID)
{
exec(“ps $PID”, $ProcessState);
return(count($ProcessState)>= 2);
}

IMO, it is more elegant to check for the exit code instead.
