Question

如何将此结构显示在多级菜单中？

这是结构：

array
  0 => 
    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)
  1 => 
    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 '2014-03-30 19:06:58' (length=19)
  2 => 
    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)
  3 => 
    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)
  4 => 
    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

输出应该是这样的：

手链
- 绚丽的手链
  - 小绚丽手链
碎花连衣裙
夏装

这是我做的，但它仍然显示子节点

function getChildren($rows, $p = 0) {
$r = array();
foreach($rows as $row) {
    if ($row['parent_node']==$p) {
        var_dump($p);
        $r[$row['product_category_code']] = getChildren($rows, $row['product_category_code']);
    }
}
return $r;

谢谢！

这是因为您已经分配了数组中的类别。您可以做的是执行将参数作为引用传递的函数，并在foreach循环中执行从已分配的类别中清除数组的功能。简单实现如下。

function getChildren(&$rows, $p = 0) {
    $r = array();
    foreach($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]);
        }
    }
    return $r;
}
