PHP陣列，追加的數組項數遞歸到數組

好吧，這是從我的另一個奇怪的一個，我要感謝OIS幫了我對我的最後一個問題......這處理這種同樣時髦的數組操作...我深入研究了代碼，並且我感覺它幫助我通過遞歸數組操作函數變得更好。然而，我再次找回自我的另一項艱鉅的現貨

實際的問題

~~我想寫一個遞歸函數操縱諸如 this。除了獲取每個數組元素的深度。~~ 它會爲每個數組元素添加一定數量的增量計數。查看我想要做的最簡單的方法是查看「樣本數組」和「期望結果數組」......我覺得我在理解這些遞歸函數方面越來越好。但是這個給了我一個地獄，提前感謝你給我提供的任何幫助。請忽略示例數組的[depth]結果，我已經有一個函數添加了這個。再次感謝， - YouDontMeanMuch

我認爲這應該w^ork ...我無法測試您的示例數組，但它似乎可以在我製作的更小的數組上工作。

編輯：現在，您已經從示例數組中刪除了「深度」鍵的功能已更改。現在它發現了它自己的深度。我還添加了我的測試代碼和輸出：

<?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); 

?>

輸出：

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 
     ) 

)

似乎無法得到這個工作的所有示例數組，我現在var_exported示例數組（在問題上編輯）。 – youdontmeanmuch 2009-02-07 10:34:33

我的功能是使用原始數組中的「深度」鍵，但現在它們消失了。我編輯函數來自己查找深度，現在它似乎可以在你的示例數組上工作。 – 2009-02-07 21:15:48

我真的很想說這將工作

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

（測試對我來說工作正常）（我誤解了這個問題的另一個例子，這應該是你想要的）
