php - 如何使用foreach获取值

Question

我正在尝试根据用户输入动态创建菜单。我有一个像这样的数组，我想通过它们的索引获取每个值，或者我想使用这些值按它们的顺序创建菜单:

$menu['main_menu']= array(
  'menu_name' =>'main_menu',
  'menu_item1'=>array('home' => array('URL' => 'Http://www.google.com','Class name'=>"item_class",'menu_id'=>'new_menu' )),
  'menu_item2'=>array('development' => array('URL' => 'Http://www.google.com','Class name'=>"item_class",'sub_menu'=>'0' )),
  'menu_item3'=>array('php' => array('URL' => 'Http://www.google.com','Class name'=>"item_class",'sub_menu'=>'development' )),
);

尝试以下代码:

foreach ($menu['main_menu'] as $item => $menu_item) {
    if (is_array($menu_item)) {
        foreach ($menu_item as $menu_name => $menu_attr) {
            echo "menu name: " . $menu_name;
            echo '<br/>';
            foreach ($menu_attr as $attr => $val) {
                echo $attr . "->" . $val;
                echo '<br/>';
            }
        }
    }
    else{
        echo $item.": ".$menu_item;
        echo "<br />";  
    }
}
