按自定义非字母顺序排序数组

Question

我有一个数组，我需要按自定义顺序排序（非字母）。我怎么能这样做？

我当前的数组如下所示：

Array
(
    [0] => Array
        (
            [id] => 29
            [title] => Christien Quint

        )

            [item_id] => 37
            [groottelid] => middel
        )

)

我想使用groottelid值对其进行排序。像这样：

groot
middel
klein

这样做的好方法是什么？

不幸的是我无法在表格中添加新列，然后我可以对结果进行排序，因此必须在数组本身上完成。
