    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++;
    }
    }
    ?>
