多维数组排序
如下

PHP code

 1    ['total'] => 2274    ['rows'] => Array    (        [0] => Array        (            ['id'] => 12            ['cell'] => Array            (                ['fid'] => 12                ['number'] => 3            )        )        [1] => Array        (            ['id'] => 13            ['cell'] => Array            (                ['fid'] => 13                ['number'] => 5            )        )        [2] => Array        (            ['id'] => 14            ['cell'] => Array            (                ['fid'] => 14                ['number'] => 2            )        )        [3] => Array        (            ['id'] => 15            ['cell'] => Array            (                ['fid'] => 15                ['number'] => 4            )        )        [4] => Array        (            ['id'] => 16            ['cell'] => Array            (                ['fid'] => 16                ['number'] => 10            )        )    ));

想变成
$arr = Array
(
['page'] => 1
['total'] => 2274
['rows'] => Array
(
[0] => Array
(
['id'] => 12
['cell'] => Array
(
['fid'] => 12
['number'] => 2
)

)

[1] => Array
(
['id'] => 13
['cell'] => Array
(
['fid'] => 13
['number'] => 3
)

)

[2] => Array
(
['id'] => 14
['cell'] => Array
(
['fid'] => 14
['number'] => 4
)

)

[3] => Array
(
['id'] => 15
['cell'] => Array
(
['fid'] => 15
['number'] => 5
)

)

[4] => Array
(
['id'] => 16
['cell'] => Array
(
['fid'] => 16
['number'] => 10
)

)

)

);[/code]
不知大家有没有好的做法

------解决方案--------------------
什么规则？按照number从小到大？

------解决方案--------------------
建议你格式化后贴出来，记得贴 var_export($arr); 后的结果。这样太伤眼睛了。
------解决方案--------------------
usort
------解决方案--------------------
原始数据
1 => array ( 'id' => 13, 'cell' => array ( 'fid' => 13, 'number' => 5, ), )
怎么变成了
1 => array ( 'id' => 13, 'cell' => array ( 'fid' => 13, 'number' => 3, ), )
