am using drupal_http_build_query and have part of my code as follows:

    $or = db_or();
    $or->condition('cid',$fField1);
    $or->condition('cid',$fField2);
    $or->condition('cid',$fField3);
    $or->condition('cid',$fField4);
    $or->condition('cid',$fField5);
    $or->condition('cid',$fField6);
    $or->condition('cid',$fField7);
    $or->condition('cid',$fField8);

    $querydata  = db_select('webform_submitted_data', 'wsd')
      ->fields('wsd',array('data'))
      ->condition('nid', $nodeID, '=')
      ->condition('sid', $sID, '=')         
      ->condition($or)
      ->execute()
      ->fetchAll();

    
    $result = array();
    $i = 1;
    foreach ($querydata as $qvalue) {
        $key = 'mapField'.$i;
        $result[] = array($$key => $qvalue->data);
        $i++;
    }

    $post_data = drupal_http_build_query($result,'', '&');

When printing the `$post_data` variable value, am getting something like this:
`name=john&1[address]=street1&2[phone]=123456789`

Notice the `1[]` and `2[]` after the `&`in the printed value. Any fix to remove these so that I get `name=john&address=street1&phone=123456789`?
