php - PHP Arrays，将数组项的计数递归地附加到数组中

Question

无意义的运球

---

好的，这是我的另一个奇怪的问题，我要感谢OIS帮助我解决了我的最后一个问题……它处理了同样的时髦数组操作……我深入研究了该代码，我觉得它有帮助递归数组操作函数让我变得更好。然而，我再次发现自己处于另一个艰难的境地

实际问题

---

我正在尝试编写一个递归操作函数，例如this。除了获取每个数组元素的深度。它将为每个具有一定深度的数组元素添加增量计数。查看我正在尝试做的最简单的方法是查看“样本数组”和“期望的结果数组”......我觉得我在理解这些递归函数方面越来越好。但是这个让我很痛苦，提前感谢你能给我的任何帮助。请忽略示例数组的 [depth] 结果我已经有一个添加它的函数。再次感谢，--YouDontMeanMuch

Answer 1

我认为这应该可以工作...我无法在您的示例数组上进行测试，但它似乎可以在我制作的较小数组上工作。

编辑：现在您已经从示例数组中删除了“深度”键，因此更改了函数。现在它自己找到了深度。我还添加了我的测试代码和输出：

<?php

function array_depth_count(&$array, $count=array(), $depth=1) {
    foreach ($array as &$value) {
        if (is_array($value)) {
            $value['count'] = ++$count[$depth];
            array_depth_count($value, $count, $depth + 1);
        }
    }
}

$a = array(array(array(array(0),array(0),array(),array()),0,array()));

echo "Before\n";
print_r($a);
array_depth_count($a);
echo "\n\nAfter\n";
print_r($a);

?>

输出：

Before
Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [0] => Array
                        (
                            [0] => 0
                        )

                    [1] => Array
                        (
                            [0] => 0
                        )

                    [2] => Array
                        (
                        )

                    [3] => Array
                        (
                        )

                )

            [1] => 0
            [2] => Array
                (
                )

        )

)

After
Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [0] => Array
                        (
                            [0] => 0
                            [count] => 1
                        )

                    [1] => Array
                        (
                            [0] => 0
                            [count] => 2
                        )

                    [2] => Array
                        (
                            [count] => 3
                        )

                    [3] => Array
                        (
                            [count] => 4
                        )

                    [count] => 1
                )

            [1] => 0
            [2] => Array
                (
                    [count] => 2
                )

            [count] => 1
        )

)

Answer 2

我真的想说这会奏效

function deep(&$layer)
{
    $count = 1;
    $keys = array_keys($layer);
    foreach($keys as $key)
        if(is_array($layer[$key]))
            deep($layer[$key]);
    $layer['depth'] = $count++;
}

（经过测试，对我来说效果很好）（我误解了这个问题的另一个例子。这应该是你想要的）
