PHP - 通过维护原始数组键按子数组值对数组进行排序

Question

我想使用其子数组值(“名称”)对数组进行排序，但保留其原始数组键。

默认数组:

Array (
    [251] => Array
        (
            [color] => 
            [name] => 8
            [nbr] => 1
            [url_name] => taille-8
            [meta_title] => 
        )

    [323] => Array
        (
            [color] => 
            [name] => 7
            [nbr] => 2
            [url_name] => taille-7
            [meta_title] => 
        )

    [127] => Array
        (
            [color] => 
            [name] => 34
            [nbr] => 2
            [url_name] => taille-34
            [meta_title] => 
        )
);

通过使用 array_multisort，我可以获得以下数组:

Array(
    [0] => Array
        (
            [color] => 
            [name] => 7
            [nbr] => 2
            [url_name] => taille-7
            [meta_title] => 
        )

    [1] => Array
        (
            [color] => 
            [name] => 8
            [nbr] => 1
            [url_name] => taille-8
            [meta_title] => 
        )

    [2] => Array
        (
            [color] => 
            [name] => 34
            [nbr] => 2
            [url_name] => taille-34
            [meta_title] => 
        )
);

但我需要的是，

Array(
    [323] => Array
        (
            [color] => 
            [name] => 7
            [nbr] => 2
            [url_name] => taille-7
            [meta_title] => 
        )

    [251] => Array
        (
            [color] => 
            [name] => 8
            [nbr] => 1
            [url_name] => taille-8
            [meta_title] => 
        )

    [127] => Array
        (
            [color] => 
            [name] => 34
            [nbr] => 2
            [url_name] => taille-34
            [meta_title] => 
        )
);

Answer 1

我会选择 uasort ，对我来说看起来简单多了:

// $arr is your Array
uasort($arr, function ($a, $b) {
  return $a['name'] - $b['name'];
});
