有困難動態

創建多級有序列表我一直想有一段時間在PHP中創建一個多層次的有序列表了。我嘗試過並一直在尋找，我看到的所有數據佈局都不同於我必須使用的數據佈局。大多數示例都會從數據庫中提取數據，並根據單獨的列構建數組，並且在這種情況下會生成具有深度或父母關係信息的列。我的數據是在一個SSRS報告路徑和2至3（或更多的未來）可以改變的水平，所以我不知道如何來構建陣列，以在這個問題上的功能工作。有困難動態

例如，一個例子是來自另一個帖子 - generating-category-tree-as-html-unordered-list，但是所有例子和我所擁有的不同之處在於數據本身的性質。

這裏是我的工作全例如：

例陣列和功能

<?php 
    $nested = Array 
    (
     1 => Array ('id' => 1, 'parent' => 0, 'title' => 'Page 1'), 
     2 => Array ('id' => 2, 'parent' => 0, 'title' => 'Page 2'), 
     3 => Array ('id' => 3, 'parent' => 0, 'title' => 'Page 3'), 
     4 => Array ('id' => 4, 'parent' => 0, 'title' => 'Page 4'), 
     5 => Array ('id' => 5, 'parent' => 0, 'title' => 'Page 5'), 
     6 => Array ('id' => 6, 'parent' => 1, 'title' => 'Page 1-1'), 
     7 => Array ('id' => 7, 'parent' => 1, 'title' => 'Page 1-2'), 
     8 => Array ('id' => 8, 'parent' => 1, 'title' => 'Page 1-3'), 
     9 => Array ('id' => 9, 'parent' => 2, 'title' => 'Page 2-1'), 
     10 => Array ('id' => 10, 'parent' => 2, 'title' => 'Page 2-2'), 
     11 => Array ('id' => 11, 'parent' => 2, 'title' => 'Page 2-3'), 
     12 => Array ('id' => 12, 'parent' => 3, 'title' => 'Page 3-1'), 
     13 => Array ('id' => 13, 'parent' => 3, 'title' => 'Page 3-2'), 
     14 => Array ('id' => 14, 'parent' => 4, 'title' => 'Page 4-1'), 
     15 => Array ('id' => 15, 'parent' => 6, 'title' => 'Page 1-1-1'), 
     16 => Array ('id' => 16, 'parent' => 6, 'title' => 'Page 1-1-2'), 
     17 => Array ('id' => 17, 'parent' => 6, 'title' => 'Page 1-1-3'), 
     18 => Array ('id' => 18, 'parent' => 7, 'title' => 'Page 1-2-1'), 
     19 => Array ('id' => 19, 'parent' => 7, 'title' => 'Page 1-2-2'), 
     20 => Array ('id' => 20, 'parent' => 7, 'title' => 'Page 1-2-3'), 
     21 => Array ('id' => 21, 'parent' => 9, 'title' => 'Page 2-1-1'), 
     22 => Array ('id' => 22, 'parent' => 9, 'title' => 'Page 2-1-2'), 
     23 => Array('id' => 23, 'parent' => 12, 'title' => 'Page 2-3-3') 
    ); 


function recursive($parent, $array) { 
    $has_children = false; 
    foreach($array as $key => $value) { 
     if ($value['parent'] == $parent) {  
     if ($has_children === false && $parent) { 
      $has_children = true; 
     echo '<ul>' ."\n"; 
     } 
     echo '<li>' . "\n"; 
     echo '<a href="/page.php?id=' . $value['id'] . '">' . $value['title'] . '</a>' . " \n"; 
     echo "\n"; 
     recursive($key, $array); 
     echo "</li>\n"; 
    } 
     } 
    if ($has_children === true && $parent) echo "</ul>\n"; 
    } 
?> 
<!DOCTYPE HTML> 
<html> 
    <head> 
     <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

    </head> 
    <body> 
     <ul><?php echo recursive(0, $nested); ?></ul> 
    </body> 
</html>

下面是數據出了SSRS報表服務器的一個例子。由於數據非常密集，它不適合代碼窗口，所以我不得不堆疊兩列。報告名稱與路徑中的最後一個元素相同，因此它有點多餘。

數據庫數據

這些數據需要需要象下面這樣的格式去與功能工作。該ID與我的目的無關，因爲報告的鏈接與報告名稱相同，因此我必須更改該功能以適合該報告。也就是說，我需要採取上面的路徑，並將其轉換爲下面的數組。

陣列格式需要

$nested2 = Array 
(
1 => Array ('parent' => 0, 'title' => 'Analyst'), 
2 => Array ('parent' => 0, 'title' => 'Membership'), 
3 => Array ('parent' => 0, 'title' => 'SLT Dashboard'), 
4 => Array ('parent' => '1', 'title' => 'POS Sales Excel Data Export'), 
5 => Array ('parent' => '1', 'title' => 'STATS Membership Tracking - RAW'), 
6 => Array ('parent' => '2', 'title' => 'Membership Dashboard'), 
7 => Array ('parent' => '6', 'title' => 'Membership Grid'), 
8 => Array ('parent' => '6', 'title' => 'Membership Grid by Service Unit'),

）;

所以，我的問題是 - 怎麼我的工作將數據轉換成一個這樣的數組？或者，使用不同的東西來創建列表會更好嗎？我知道我可以通過列表迭代，可能需要每個元素比較報告名字就知道在哪裏停止，父母是誰，等等，但在那之後那種迷失方向。

與往常一樣，許多在此先感謝。

我寫了一個簡單的解決方案（希望對你有用，你可以修改你的想法）。但我只用一節PATH（做什麼用的部分NAME - 不明白）。

$filename = 'path.txt'; // put section PATH to file for convenience 
$lines = file($filename); 

$tree = array(); 

foreach($lines as $line){ 

    $items = array_filter(explode('/',$line)); 
    $branch = array(); 
    $ptr = &$branch; 
    foreach($items as $item){ 
     $ptr[$item] = Array(); 
     $ptr = &$ptr[$item]; 
    } 
    unset($ptr); 

    if (empty($tree)){ 
     $tree = $branch; 
    }else{ 
     $tree = array_merge_recursive($tree,$branch); 
    } 

} 

// output tree 
echo '<pre>'; 
var_dump($tree); 
echo '</pre>';

輸出

array(1) { 

    ["Production"]=> 
     array(6) { 

      ["Analyst"]=> 
       array(2) { 
        ["POS Sales Excel Data Export"]=> array(0) {}

感謝 - 這個名字只是數據我是從表中獲取的第二列 - 正如我上面提到的，因爲它是路徑的一部分，它可能是無論如何。 – 43rdworld

對不起 - 不知道有一個評論計時器....我有點看到你在做什麼，但它不適用於該功能，我不知道該怎麼做來改變它。如果我能得到它適合該功能的格式，我可以改變一些東西來處理數據庫。任何關於如何做到這一點的指針？ – 43rdworld
