从嵌套的分层数据或数组

Question

我想制作菜单，分层数据类别。我可以在数组中提取，但我必须生成菜单。这就是我所做的：

Array (
    [17] => Array ( 
        [cat_id] => 17,
        [section_left] => 200,
        [section_right] => 211,
        [section_level] => 1,
        [section_name] => Bauturi,
        [nflag] => 1 ),
    [22] => Array ( 
        [cat_id] => 22,
        [section_left] => 201,
        [section_right] => 204,
        [section_level] => 2,
        [section_name] => Bere,
        [nlag] => 1 ),
    [32] => Array ( 
        [cat_id] => 32,
        [section_left] => 202,
        [section_right] => 203,
        [section_level] => 3,
        [section_name] => Fara Alool,
        [nflag] => 0 ),
    [31] => Array ( 
        [cat_id] => 31,
        [section_left] => 205,
        [section_right] => 210,
        [section_level] => 2,
        [section_name] => Cu Alcol,
        [nflag] => 1 ),
    [34] => Array ( 
        [cat_id] => 34,
        [section_left] => 206,
        [section_right] => 207,
        [section_level] => 3,
        [section_name] => Tuborg,
        [nflag] => 0 ),
    [58] => Array ( 
        [cat_id] => 58
        [section_left] => 208
        [section_right] => 209
        [section_level] => 3
        [section_name] => uuuu5 
        [nflag] => 0)
) 
Array ( 
    [18] => Array ( 
        [cat_id] => 18,
        [section_left] => 212,
        [section_right] => 219,
        [section_level] => 1,
        [section_name] => Patiserie,
        [nflag] => 1 ),
    [23] => Array ( 
        [cat_id] => 23,
        [section_left] => 213,
        [section_right] => 214,
        [section_level] => 2,
        [section_name] => Prajituri,
        [nflag] => 0 ),
    [24] => Array ( 
        [cat_id] => 24,
        [section_left] => 215,
        [section_right] => 218,
        [section_level] => 2,
        [section_name] => Ciocolata,
        [nflag] => 1 ),
    [33] => Array ( 
        [cat_id] => 33,
        [section_left] => 216,
        [section_right] => 217,
        [section_level] => 3,
        [section_name] => Beks,
        [nflg] => 0 )
)
.
.
.

使用此代码我获取该菜单，但我有一个错误。我必须得到所有的孩子并为每个孩子制作一个子菜单，例如第一项，

• BAUTURI 1
• --BERE 2
• -----Fara Alcool 3
• --Cu alcool
• -----Tuborg 3
• -----uuuuu5 3

我的问题是，如何在数据库中为项目构建该foreach以在页面中正确显示？
