php 二维数组排序

<?php
$arr = [
    [
        'id' => 4,
        'name' => 'si',
    ],
    [
        'id' => 1,
        'name' => 'yi',
    ],
    [
        'id' => 2,
        'name' => 'er',
    ],
    [
        'id' => 5,
        'name' => 'wu',
    ],
    [
        'id' => 3,
        'name' => 'san',
    ],
];

$sort_column = array_column($arr, 'id');
array_multisort($sort_column, SORT_DESC, $arr);

echo '<pre>';
print_r($arr);
die;

 

 

结果:

 

Array
(
    [0] => Array
        (
            [id] => 5
            [name] => wu
        )

    [1] => Array
        (
            [id] => 4
            [name] => si
        )

    [2] => Array
        (
            [id] => 3
            [name] => san
        )

    [3] => Array
        (
            [id] => 2
            [name] => er
        )

    [4] => Array
        (
            [id] => 1
            [name] => yi
        )

)
