array(
(int) 0 => array(
    'MenuCategory' => array(
     'name' => 'Setting' 
    ), 
    'Menu' => array(
     'name' => 'Menu Category', 
     'url' => '/menu_categories/adding', 
     'parent_id' => null 
    ), 
    'Site' => array(
     'id' => (int) 1 
    ), 
    'Sub' => array(
     'name' => 'Menu Category View', 
     'url' => '/menu_categories/view' 
    ) 
), 
(int) 1 => array(

     'name' => 'Setting' 
    ), 
    'Menu' => array(

Answer 1

你可以通过它简单地循环使用三个嵌套foreach()循环，就像这样：

$arr = // your array; 
echo "<ul>"; 
foreach($arr as $setting => $nested) { 
    echo "<li>$setting<ul>"; 
    foreach($nested as $category => $nested2) { 
     echo "<li>$category</li><ul>"; 
     foreach($nested2 as $view) { 
      echo "<li>$view</li>"; 
     } 
     echo "</ul></li>"; 
    } 
    echo "</ul></li>"; 
} 
echo "</ul>"; 

与此唯一的问题是，它可能会打印出不必要的（空）<ul> s，而该<ul>的默认到不同的子弹类型（很容易用CSS修复）。

在PHP Sandbox或Ideone处进行测试。下面是输出提供：

<ul><li>setting<ul><li>menu category</li><ul><li>menu category view</li></ul></li><li>group</li><ul><li>group view</li></ul></li><li>deposits</li><ul></ul></li><li>group menu</li><ul><li>group menu array</li></ul></li><li>menu</li><ul><li>menu view</li></ul></li></ul></li></ul>
