There is another approach and its worthwhile considering if you don't want to tamper with the response headers. If you start a thread on another process the called function wont wait for its response and will return to the browser with a finalized http code. You will need to configure pthread.

class continue_processing_thread extends Thread 
{
     public function __construct($param1) 
     {
         $this->param1 = $param1
     }

     public function run() 
     {
        //Do your long running process here
     }
}

//This is your function called via an HTTP GET/POST etc
function rest_endpoint()
{
  //do whatever stuff needed by the response.

  //Create and start your thread. 
  //rest_endpoint wont wait for this to complete.
  $continue_processing = new continue_processing_thread($some_value);
  $continue_processing->start();

  echo json_encode($response)
}

Once we execute $continue_processing->start() PHP wont wait for the return result of this thread and therefore as far as rest_endpoint is considered. It is done.
