重置多维数组中的数组键

Question

我一直在寻找解决方案,但没有取得真正的成功.我有一个多维的父母和孩子阵列,对深度没有限制.这是从数据库生成的,但问题是项目ID成为关键,使用我的方式将平面数组排列成多维数组,如下所示:

Array(

[28] => Array
        (
            [id] => 28
            [color] => #ff24e5
            [name] => Personal
            [parent_id] => 
            [children] => Array
                (
                    [23] => Array
                        (
                            [id] => 23
                            [color] => #41c3a3
                            [name] => Shopping
                            [parent_id] => 28
                            [children] => Array
                                (
                                    [22] => Array
                                        (
                                            [id] => 22
                                            [color] => #8be32b
                                            [name] => Deals
                                            [parent_id] => 23
                                            [children] => Array
                                                (
                                                )
                                        )
                                )
                        )

                    [150] => Array
                        (
                            [id] => 150
                            [color] => #e9a3f0
                            [name] => Orders
                            [parent_id] => 28
                            [children] => Array
                                (
                                )
                        )
                )
        )
)

我想要的是一个执行以下操作的功能:

Array (
[0] => Array
        (
            [id] => 28
            [color] => #ff24e5
            [name] => Personal
            [parent_id] => 
            [children] => Array
                (
                    [0] => Array
                        (
                            [id] => 23
                            [color] => #41c3a3
                            [name] => Shopping
                            [parent_id] => 28
                            [children] => Array
                                (
                                    [0] => Array
                                        (
                                            [id] => 22
                                            [color] => #8be32b
                                            [name] => Deals
                                            [user_id] => 1
                                            [selected] => 0
                                            [parent_id] => 23
                                            [children] => Array
                                                (
                                                )
                                        )
                                )
                        )

                    [1] => Array
                        (
                            [id] => 150
                            [color] => #e9a3f0
                            [name] => Orders
                            [parent_id] => 28
                            [children] => Array
                                (
                                )
                        )
                )
        )
)

基本上从0开始重新分配密钥.我尝试了很多方法,但我假设我需要找到一个递归解决方案,当我尝试它时,它会破坏我的数组.我正在阅读array_walk_recursive()函数,但我不知道该怎么做.基本上,有没有办法重置多维数组中的数字键？

谢谢您的帮助!

Answer 1

你真的需要添加is_numeric条件来阻止文本键混淆...

function fix_keys($array) {

    foreach ($array as $k => $val) {

        if (is_array($val)) 
            $array[$k] = $fix_keys($val); //recurse
    }

    if( is_numeric($k) )
        return array_values($array);

    return $array;
}

我这样做了:

function fix_keys($array) {
    $numberCheck = false;
    foreach ($array as $k => $val) {
        if (is_array($val)) $array[$k] = fix_keys($val); //recurse
        if (is_numeric($k)) $numberCheck = true;
    }
    if ($numberCheck === true) {
        return array_values($array);
    } else {
        return $array;
    }
}

Answer 2

function fix_keys($array) {
  foreach ($array as $k => $val) {
    if (is_array($val)) 
      $array[$k] = fix_keys($val); //recurse
  }
  return array_values($array);
}

Answer 3

我试图修复同样的问题,这是代码

$array = array_values($array);
