无意义运球
好的,这是我的另一个奇怪的事情,我要感谢OIS帮助我解决我的最后一个问题......它涉及这种类似的时髦数组操作...我研究了那个代码深度,我觉得它有助于我通过递归数组操作函数变得更好。然而,我又一次在另一个艰难的地方找到了自己
实际问题
我正在尝试编写递归操作函数,例如this。获取每个数组元素的深度除外。 它会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方法是查看“示例” array“和”Desired result Array“......我觉得我在理解这些递归函数方面变得越来越好。但是这个给了我地狱,感谢您提前给予我任何帮助。
请忽略示例数组的[深度]结果我已经有一个添加它的函数。
再次感谢,

我认为这应该可以工作......我无法测试你的示例数组,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,因此更改了此功能。现在它自己找到了深度。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
)
)

我真的想说这会起作用
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,对我来说很好) (另一个我误解了这个问题的案例。这应该是你想要的)
