PHP数组使用特定键值对关联数组进行排序

PHP数组使用特定键值对关联数组进行排序,php,arrays,sorting,multidimensional-array,Php,Arrays,Sorting,Multidimensional Array,我有一个数组,需要使用键值“odbyx”进行排序 这是数组var\u dump array(12) { ["id"]=> array(7) { [0]=> string(1) "8" [1]=> string(1) "7" [2]=> string(1) "3" [3]=> string(1) "6" [4]=> string(1) "5" [5]=>

阵列背后的逻辑

$array = array
        (
        "id" => $id,
        "subject" => $subject,
        "msg" => $msg,
        "department" => $department,
        "priorety" => $priorety,
        "status" => $status,
        "dateAded" => $dateAded,
        "dateClosed" => $dateClosed,
        "dateActivity" => $dateActivity,
        "userId" => $userId,
        "res" => $res,
        "odbyx"=>$odbyx
        );
我尝试使用下面的代码进行排序,但似乎不起作用

array_multisort(array_column($array, 'odbyx'), SORT_DESC, $array);
odbyx字段保存优先级值(1,2,3)

我需要使用该值对主数组进行排序,这样我就可以在表的开始位置显示最高优先级字段

我想使用“odbyx降序对$array进行排序

id数组的示例输出,其他数组也需要立即排序。

["id"]=> array(7) { [0]=> string(1) "6" [1]=> string(1) "5" [2]=> string(1) "4" [3]=> string(1) "3" [4]=> string(1) "7" [5]=> string(1) "6" [6]=> string(1) "8" } 
正确使用 另见:

您的示例是无效的 预期结果中的第一个条目:
0=>6'

可能的解释
odbyx索引==id索引
odbyx
中的索引是否应与
id
中的索引匹配

i、 e.:
$array['id'][3]
应按
$array['odbyx'][3]

如果是这种情况,那么您提供的代码应该为第一个索引生成
0=>'8'
(odbyx 1的优先级高于3),或者
0=>'1'
(3更高)

可能的解释
odbyx索引==id值
odbyx
中的索引是否应与
id
中的id值匹配

i、 例如:
$array['odbyx'][1]
的值决定了
$array['id'][6]='1'

在这种情况下,结果应该是
0=>2'

所有这些可能的解释都与示例中的第一个结果不匹配。这里的课程是规范,即:在stackoverflow或其他任何地方,仔细定义和描述解决问题所需的具体条件

这是一个开始 由于您要求解决的问题很复杂,定义不明确,需要大量的编码和测试,并且对性能有重大影响,因此我将为您提供上述不可能解释之一的解决方案。祝你好运
