毫无意义的运球
好吧，这是我的另一个奇怪的事情，我要感谢OIS为了帮助我解决我的最后一个问题...它涉及同样类型的时髦数组操作...我深入研究了该代码，我觉得它帮助我更好地使用递归数组操作函数。然而，我再次发现自己陷入了另一个困境
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之外。 它将为具有一定深度的每个数组元素添加增量计数。了解我正在尝试执行的操作的最简单方法是查看“示例”数组”和“所需结果数组”...我觉得我越来越能更好地理解这些递归函数。但这让我很痛苦，提前感谢您在这方面给我的任何帮助。
请忽略示例数组的 [深度] 结果，我已经有一个添加此结果的函数。
再次感谢，
——你别太刻薄

最佳答案
我认为这应该可行...我无法在您的示例数组上进行测试，但它似乎适用于我制作的较小数组。
编辑:现在您已从示例数组中删除了“深度”键，因此更改了函数。现在它自己找到深度。我还添加了测试代码和输出:
<?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
)
)
