Spawning multiple processes with PHP to proccess data

[M7AMD]

I have a queue (Amazon SQS) of data that needs to be processed, and I would like to do it with multiple processes (in PHP).I want the child workers to do something like this (pseduoish code):\[code\]while(true) { $array = $queue->fetchNItems(10); // get 10 items if(!count($array)) killProcess(); foreach($array as $item) { ... // process the item $queue->remove($item); } sleep(2);}\[/code\] I always need 1 child process to be running, but in times of need I want to (fork?) a child process so that it can help process the queue faster.Can someone help me with a rough PHP skeleton of what I need, or point me in the right direction?I think I need to take a look at http://php.net/manual/en/function.pcntl-fork.php, but I'm not sure how I can use this to manage multiple processes.Thanks
