Question

我有一篇关于此问题的帖子虽然我现在有一个与同一主题相关的不同问题但已经回答了。您可能想在此处参考原始问题。 php display multilevel treenode menu

既然数组是通过树节点显示的，那么它似乎不是完全递归的。我注意到，当第一个元素是子节点时，它不会显示为子节点。

我尝试过krsort然后ksort。

function getChildren(&$rows, $p = 0) {
    $r = array();
    krsort($rows);
    foreach($rows as $row_id => $row) {
        if ($row['parent_node']==$p) {
            $r[$row['product_category_code']] = getChildren($rows, $row['product_category_code']);
            unset($rows[$row_id]);
        }
    }
    ksort($rows);
    return $r;
}

这是数组的结构：

array
  0 => 
    array
      'product_category_code' => string 'akamia' (length=6)
      'product_category_desc' => string 'Akamia' (length=6)
      'parent_node' => string 'summer-dress' (length=12)
      'inactive' => string '0' (length=1)
      'sort' => string '0' (length=1)
      'created_by' => string '1' (length=1)
      'created_date' => string '2014-04-01 10:03:42' (length=19)
      'modified_by' => string '1' (length=1)
      'modified_date' => string '2014-04-01 10:03:47' (length=19)
  1 => 
    array
      'product_category_code' => string 'bracelets' (length=9)
      'product_category_desc' => string 'Bracelets' (length=9)
      'parent_node' => string '' (length=0)
      'inactive' => string '0' (length=1)
      'sort' => string '0' (length=1)
      'created_by' => string '1' (length=1)
      'created_date' => string '2014-03-14 22:04:08' (length=19)
      'modified_by' => string '1' (length=1)
      'modified_date' => string '2014-03-14 22:09:05' (length=19)
  2 => 
    array
      'product_category_code' => string 'floral-dress' (length=12)
      'product_category_desc' => string 'Floral Dress' (length=12)
      'parent_node' => string '' (length=0)
      'inactive' => string '0' (length=1)
      'sort' => string '0' (length=1)
      'created_by' => string '1' (length=1)
      'created_date' => string '2014-03-14 22:09:49' (length=19)
      'modified_by' => string '1' (length=1)
      'modified_date' => string '2014-04-01 10:03:30' (length=19)
  3 => 
    array
      'product_category_code' => string 'flowery-bracelets' (length=17)
      'product_category_desc' => string 'Flowery Bracelets' (length=17)
      'parent_node' => string 'bracelets' (length=9)
      'inactive' => string '0' (length=1)
      'sort' => string '0' (length=1)
      'created_by' => string '1' (length=1)
      'created_date' => string '2014-03-14 22:09:16' (length=19)
      'modified_by' => string '1' (length=1)
      'modified_date' => string '2014-03-30 19:08:44' (length=19)
  4 => 
    array
      'product_category_code' => string 'small-flowery-bracelets' (length=23)
      'product_category_desc' => string 'Small Flowery Bracelets' (length=23)
      'parent_node' => string 'flowery-bracelets' (length=17)
      'inactive' => string '0' (length=1)
      'sort' => string '0' (length=1)
      'created_by' => string '1' (length=1)
      'created_date' => string '2014-03-14 22:08:35' (length=19)
      'modified_by' => string '1' (length=1)
      'modified_date' => string '2014-03-30 19:09:44' (length=19)
  5 => 
    array
      'product_category_code' => string 'summer-dress' (length=12)
      'product_category_desc' => string 'Summer Dress' (length=12)
      'parent_node' => string '' (length=0)
      'inactive' => string '0' (length=1)
      'sort' => string '0' (length=1)
      'created_by' => string '1' (length=1)
      'created_date' => string '2014-03-14 22:09:29' (length=19)
      'modified_by' => string '0' (length=1)
      'modified_date' => null

输出（没有krsort / ksort）显示了这个，这是错误的：

Akamai的
手链
- 绚丽的手链
  - 小绚丽手链
碎花连衣裙
夏装

这应该是输出：

手链
- 绚丽的手链
  - 小绚丽手链
碎花连衣裙
夏装
- Akamai的

Answer 1

没关系，我得到了答案。由于数组上的父节点为空，$p上的function getChildren(&$rows, $p = 0)应为$p = ''而不是零（0）。傻我。 XD
