按他的值的 1 对多维数组进行排序

Question

首先，我检查并尝试了这些链接：

Sort Multi-dimensional Array by Value

Sort Multi-dimensional Array by Value

Sort php multidimensional array by sub-value

http://www.paulund.co.uk/sort-multi-dimensional-array-value

http://php.net/manual/fr/function.array-multisort.php.

所以这是我的问题。我需要根据键的值将数组排序为多维数组。

如果我这样做，这就是结构：print($myarray)

Array ( 
    [afctname1] => Array ( 
    [active] => 1 
    [icons] => Array ( 
        [0] => Array ( 
            [permalink] => afctname1 
            [ordering] => 2 
        ) 
     ) 
 )
 Array ( 
    [afctname2] => Array ( 
    [active] => 1 
    [icons] => Array ( 
        [0] => Array ( 
            [permalink] => afctname2 
            [ordering] => 0 
        ) 
     ) 
 )
 Array ( 
    [afctname3] => Array ( 
    [active] => 1 
    [icons] => Array ( 
        [0] => Array ( 
            [permalink] => afctname3 
            [ordering] => 1 
        ) 
     ) 
 )

所以我想要的只是按键“ordering”中的值对数组进行排序。

有人可以给我提示或帮助我进行演示吗？ 谢谢

Answer 1

function cmp($a, $b)
{
    return $a['icons'][0]['ordering'] - $b['icons'][0]['ordering'];
}

usort($theArray, "cmp");
