Question

我具有以下数组结构，但我需要按标记值排序，并且在重复时需要最后按数组索引排序：

这是我的数组基础$AsocContData[$s_list_100]：

array(5) {
    [01081] => Array(3){
        [id] => 2
        [Mark] => 420
        [lastUpdated] => 2010-03-17 15:44:12
        [dataNext] => Array(2){
            [more1] => 54
            [More2] => 54
        }
    }
    [00358] => Array(3){
        [id] => 6
        [Mark] => 500
        [lastUpdated] => 2010-03-17 15:44:12
        [dataNext] => Array(2){
            [more1] => 54
            [More2] => 54
        }
    }
    [00277] => Array(3){
        [id] => 3
        [Mark] => 400
        [lastUpdated] => 2010-03-17 15:44:12
        [dataNext] => Array(2){
            [more1] => 54
            [More2] => 54
        }
    }
    [00357] => Array(3){
        [id] => 1
        [Mark] => 500
        [lastUpdated] => 2010-03-17 15:44:12
        [dataNext] => Array(2){
            [more1] => 54
            [More2] => 54
        }
    }
}

按子数组排序数组并重复使用索引数组的最佳方法是什么？

结果如下：

array(5) {
    [00277] => Array(3){
        [id] => 3
        [Mark] => 400
        [lastUpdated] => 2010-03-17 15:44:12
        [dataNext] => Array(2){
            [more1] => 54
            [More2] => 54
        }
    }
    [01081] => Array(3){
        [id] => 2
        [Mark] => 420
        [lastUpdated] => 2010-03-17 15:44:12
        [dataNext] => Array(2){
            [more1] => 54
            [More2] => 54
        }
    }
    [00357] => Array(3){
        [id] => 1
        [Mark] => 500
        [lastUpdated] => 2010-03-17 15:44:12
        [dataNext] => Array(2){
            [more1] => 54
            [More2] => 54
        }
    }
    [00358] => Array(3){
        [id] => 6
        [Mark] => 500
        [lastUpdated] => 2010-03-17 15:44:12
        [dataNext] => Array(2){
            [more1] => 54
            [More2] => 54
        }
    }
}

更新

我尝试使用它，但是在php 7.2中它没有所需的作用域：

usort($AsocContData[$s_list_100], function ($a, $b) {
    return $a['Prod_Mark'] <=> $b['Prod_Mark'];
});

此返回，不对重复项进行排序：

array(20) {
  [0]=>// remplace this first Index array with position and it is a fail.
  array(38) {

  }
}

更新

基本数组是动态嵌套的，可以嵌套更多的Array子级。

<?php
$list = [
    277 => [
        'id' => 3,
        'Mark' => 400,
        'lastUpdated' => '2010-03-17 15:44:12'
    ],
    1081 => [
        'id' => 2,
        'Mark' => 420,
        'lastUpdated' => '2010-03-17 15:44:12'
    ],
    357 => [
        'id' => 1,
        'Mark' => 500,
        'lastUpdated' => '2010-03-17 15:44:12'
    ],
    358 => [
        'id' => 6,
        'Mark' => 500,
        'lastUpdated' => '2010-03-17 15:44:12'
    ]
];

$tmp = array_column($list, 'Mark');
array_multisort($tmp, SORT_ASC, array_keys($list), SORT_ASC, $list);
var_dump($list);

应该这样做

Answer 2

您可能应该使用array_multisort()

array_multisort(
    array_column( $AsocContData[$s_list_100], 'Mark' ), // sort by the Mark sub-array value first
    SORT_ASC, // ascending
    SORT_NUMERIC, // treat data as numeric
    array_keys( $AsocContData[$s_list_100] ), // secondly, sort by the array indexes
    SORT_ASC, // ascending
    SORT_NUMERIC, // treat indexes as numeric
    $AsocContData[$s_list_100] // this array will be sorted in place and by reference
);

var_dump( $AsocContData[$s_list_100] );

输入：

$AsocContData[$s_list_100] = array(
    '01081' => Array(
        'id' => 2,
        'Mark' => 420,
        'lastUpdated' => '2010-03-17 15:44:12'
    ),
    '00358' => Array(
        'id' => 6,
        'Mark' => 500,
        'lastUpdated' => '2010-03-17 15:44:12'
    ),
    '00277' => Array(
        'id' => 3,
        'Mark' => 400,
        'lastUpdated' => '2010-03-17 15:44:12'
    ),
    '00357' => Array(
        'id' => 1,
        'Mark' => 500,
        'lastUpdated' => '2010-03-17 15:44:12'
    )
);

输出：

Array
(
    [00277] => Array
        (
            [id] => 3
            [Mark] => 400
            [lastUpdated] => 2010-03-17 15:44:12
        )

    [01081] => Array
        (
            [id] => 2
            [Mark] => 420
            [lastUpdated] => 2010-03-17 15:44:12
        )

    [00357] => Array
        (
            [id] => 1
            [Mark] => 500
            [lastUpdated] => 2010-03-17 15:44:12
        )

    [00358] => Array
        (
            [id] => 6
            [Mark] => 500
            [lastUpdated] => 2010-03-17 15:44:12
        )

)

按子数组值对数组索引排序
