PHP与阵列的多级菜单（新）

Question

I don't know if it's authorize (sorry if not), but this post follow this link Multi level menu with PHP with array

I rewrited the code like this because iterator doesn't work in my case , I think. I tried to create an automatic menu, but I have a problem to display array who begin at apps1

Idea ? Thank you

my array

  $cl_box_groups[] = array(
                          'level_title' => BOX_HEADING_CONFIGURATION,
                          'level_class' => 'fa fa-sun-o',

                          'apps' => array(
                            array(
                              'level_title' => MENU_CONFIGURATION_STORE,
                              'level_class' => 'fa fa-sun-o'
                            ),

                            'apps1' => array (
                              array('level_title' => MENU_CONFIGURATION_GENERAL,
                                    'level_class' => '',
                                    'level_link' => 'configuration.php?gID=1',
                              ),
                              array('level_title' => MENU_CONFIGURATION_LEGACY,
                                    'level_class' => '',
                                    'level_link' => 'configuration.php?gID=25',
                              ),
                            ),
                          ),
                          );

But with this code, I have all result but If I apply it in my html, it doesn't work for apps1

 echo '<pre>';
  foreach ($cl_box_groups as $groups) {
    print_r($groups);
    foreach($groups['apps'] as $app) {
      print_r($app);
      foreach($app['apps1'] as $apps1) {
        print_r($apps1);
      }
    }
  }
echo '</pre>';

result

<pre>Array
(
    [level_title] => Configuration
    [level_class] => fa fa-sun-o
    [apps] => Array
        (
            [0] => Array
                (
                    [level_title] => Ma boutique
                    [level_class] => fa fa-sun-o
                )

            [apps1] => Array
                (
                    [0] => Array
                        (
                            [level_title] => Configuration générale
                            [level_class] => 
                            [level_link] => configuration.php?gID=1
                        )

                    [1] => Array

                            [level_class] =>
