Array:
<code>Array ( [0] => Array ( [id] => 1 [menu_collapse] => 超级菜单 [menu_items] => 写文章 [cid] => 1 ) [1] => Array ( [id] => 2 [menu_collapse] => 维护菜单 [menu_items] => 管理数据 [cid] => 2 ) [2] => Array ( [id] => 3 [menu_collapse] => 维护菜单 [menu_items] => 管理用户 [cid] => 2 ) )</code>
Wie konvertiere ich das obige Array in dieses?
