移动多维数组中的元素。 [英] Move elements in a multidimensional array.

问题描述

我有父母和孩子的多维数组，我想改变数组键

它看起来是这样的：

 阵列
（
    [0] =＆GT; stdClass的对象
    （
        [ID] =＆GT; 108
        [PARENT_ID] =＆GT; 0
        [儿童] =＆GT;排列
        （
            [0] =＆GT; stdClass的对象
            （
                 [ID] =＆GT; 71
                 [PARENT_ID] =＆GT; 108
                 [儿童] =＆GT;排列
                 （
                     [0] =＆GT; stdClass的对象
                     （
                         [ID] =＆GT; 107
                         [PARENT_ID] =＆GT; 71
                         [儿童] =＆GT;排列
                         （
                             [0] =＆GT; stdClass的对象
                             （
                                 [ID] =＆GT; 78
                                 [PARENT_ID] =＆GT; 107
                             ）
                         ）
                    ）
                ）
            ）
        ）
    ）    [1] =＆GT; stdClass的对象
    （
        [ID] =＆GT; 82
        [PARENT_ID] =＆GT; 0
    ）    [2] =＆GT; stdClass的对象
    （
        [ID] =＆GT; 84
        [PARENT_ID] =＆GT; 0
    ）    [3] =＆GT; stdClass的对象
    （
        [ID] =＆GT; 88
        [PARENT_ID] =＆GT; 0
    ）    [4] =＆GT; stdClass的对象
    （
        [ID] =＆GT; 92
        [PARENT_ID] =＆GT; 0
    ）
）
 

我要移动，例如，与阵列下方的ID 108的阵列[ID] => 88的问题是一个数组移动到新的位置，而且还移动子阵列

解决方案

 函数array_remove（$数组$指数）{
    array_splice（$数组$指数，1，阵列（））;
    返回$阵列;
}功能array_insert（$数组，$元，$指数）{
    array_splice（$数组$指数，0阵列（$元素））;
    返回$阵列;
}功能ARRAY_MOVE（$阵列，从$，$到）{
    $元= $阵列[从$]。
    $阵列= array_remove（$阵列，从$）;
    $阵列= array_insert（$数组，$元，$至 -  1）;
    返回$阵列;
}$阵列= ARRAY_MOVE（$阵列，0，4）;
的print_r（$数组）;
 

I have a multidimensional array with parents and childs and i want to change the array keys

It looks like this:

Array
(
    [0] => stdClass Object
    (
        [id] => 108
        [parent_id] => 0
        [children] => Array
        (
            [0] => stdClass Object
            (
                 [id] => 71
                 [parent_id] => 108
                 [children] => Array
                 (
                     [0] => stdClass Object
                     (
                         [id] => 107
                         [parent_id] => 71
                         [children] => Array
                         (
                             [0] => stdClass Object
                             (
                                 [id] => 78
                                 [parent_id] => 107
                             )
                         )
                    )
                )
            )
        )
    )

    [1] => stdClass Object
    (
        [id] => 82
        [parent_id] => 0
    )

    [2] => stdClass Object
    (
        [id] => 84
        [parent_id] => 0
    )

    [3] => stdClass Object
    (
        [id] => 88
        [parent_id] => 0
    )

    [4] => stdClass Object
    (
        [id] => 92
        [parent_id] => 0
    )
)

I want to move, for example, the array with the id 108 below the array [id] => 88. The problem is to move an array to a new position but moving also the child arrays.

解决方案

function array_remove($array, $index) {
    array_splice($array, $index, 1, array());
    return $array;
}

function array_insert($array, $element, $index) {
    array_splice($array, $index, 0, array($element));
    return $array;
}

function array_move($array, $from, $to) {
    $element = $array[$from];
    $array = array_remove($array, $from);
    $array = array_insert($array, $element, $to - 1);
    return $array;
}

$array = array_move($array, 0, 4);
print_r($array);
