如何用foreach制作一个亲子？

Question

您好我试着做类似的事情 我的疑问：

result = mysql_query（'SELECT subitems.ItemID，subitems.Parent，subitems.Data，items.ID FROM subitems INNER JOIN items ON items.ID = subitems.ItemID WHERE subitems.ItemID = \''。$ item [' ID']。'\'GROUP BY subitems.Parent ASC，subitems.Data ASC'）;

阵   （

[ItemID] => 1
    (
      [Parent] => 1
          (
              [Data] => 1
              [Data] => 2
              [Data] => 3
          )
    )

[ItemID] => 1
    (
      [Parent] => 2
          (
              [Data] => 1
              [Data] => 2
              [Data] => 3
          )
    )

）

我尝试制作foreach以查看itemID的每个父项并按父项显示每个项目，但不是每次都重写父项的名称。 THX

也许是嵌套的foreach（es）

 foreach ($array as $item) {
    foreach ($item as $parent) {
        foreach ($parent as $data) {
            echo $data;
        }
    }
 }
