在php中从一维数组创建嵌套的父子数组

Question

我有2个阵列.

第一阵列:

$array = array( 
   'a' => 'b',
   'b' => 'c',
   'c' => 'd',
);

第二阵列:

 $array =  Array
    (
        [a] => Array
            (
                [0] => b
                [1] => h
            )

        [b] => c
        [c] => d
        [h] => m
    )

我需要改变这个数组

第一个阵列:

Array
(
    [a] => Array
        (
            [b] => Array
                (
                    [c] => Array
                        (
                            [d] => d
                        )

                )

        )

)

第二阵列:

Array
(
    [a] => Array
        (
            [b] => Array
                (
                    [c] => Array
                        (
                            [d] => Array
                                (
                                )

                        )

                )

            [h] => Array
                (
                    [m] => Array
                        (
                        )

                )

        )

)

您可以尝试使用&(引用):

PHP:

    $array = array( 
       'a' => 'b',
       'b' => 'c',
       'c' => 'd',
    );

    $newArray = array();
    $newArray[key($array)] = array();
    $part = &$newArray;

    foreach($array as $first => $second){
        $part = &$part[$first];
        $part[$second] = array();
    }

    echo "<pre>";
    print_r($newArray);
    echo "</pre>";

?>

结果:

Array
(
    [a] => Array
        (
            [b] => Array
                (
                    [c] => Array
                        (
                            [d] => Array
                                (
                                )

                        )

                )

        )

)

然后你可以为最后一部分创建一个循环.
