Keep in mind that mysqli::reap_async_query only returns mysqli_result on queries like SELECT. For queries where you may be interested in things like affected_rows or insert_id, you can't work off of the result of mysqli::reap_async_query as the example in mysqli::poll leads you to believe. For INSERT/UPDATE/DELETE queries, the data corresponding to the query can be accessed through the associated key to the first array in the mysqli::poll function.
So instead of
<?php
  foreach ($links as $link) {
    if ($result = $link->reap_async_query()) {
      print_r($result->fetch_row());
      mysqli_free_result($result);
      $processed++;
    }
  }
?>
The data is accessible via:
<?php
  foreach ($links as $link) {
    if ($result = $link->reap_async_query()) {
      //This works for SELECT
      if(is_object($result)){
        print_r($result->fetch_row());
        mysqli_free_result($result);
      }
      //This works for INSERT/UPDATE/DELETE
      else {
        print_r($link);
      }
      $processed++;
    }
  }
?>
