[PHP] Złączenie tablic przed danym elementem Opcje

[potreb]

Witam, mam problem z jedną rzeczą a dokładnie:

[PHP] pobierz, plaintext 
  function tree()
  {
    $sql = $this->pdo->query("SELECT * FROM `plugins` ORDER BY `ptitle`");
    $tree[] = array('section_id' => 2, 'section_parent_id' => '1', 'section_name' => 'Użytkownicy', 'section_module' => '#', 'section_plugin' => '', 'depth' => 1);
    $tree[] = array('section_id' => 3, 'section_parent_id' => '1', 'section_name' => 'System', 'section_module' => '#', 'section_plugin' => '', 'depth' => 1);
    $tree[] = array('section_id' => 4, 'section_parent_id' => '1', 'section_name' => 'Zawartość', 'section_module' => '#', 'section_plugin' => '', 'depth' => 1);
 
    $i = 4;
    while($r = $sql->fetch(PDO::FETCH_OBJ))
    {
      $tree[] = array('section_id' => $i, 'section_parent_id' => $r->prights+1, 'section_name' => $r->ptitle, 'section_module' => $r->plink, 'section_plugin' => $r->pinstall, 'depth' => 2);
      $i++;
    }
    return $tree;
  }

Wyświetla mi tablicę w takiej postaci:

[HTML] pobierz, plaintext 

Pierwsze trzy elementy powinny być wstawione przed tablicę, która zawiera wartość section_parent_id równą section_id. Niestety nie wiem jaką funkcję zastosować, aby połączyć tablicę, tak aby te 3 elementy znalazły się przed pierwszym elementem swojej podkategorii.

Mógłbym to zrobić innym sposobem, jednak jestem ciekaw czy jest jakaś funkcja, która pozwoli to zrobić szybciej
