以上数组由mysql联表查询得到的数据，但存在数据重复，无主副标题的差异固需将数据通过php重新格式话:

#重新定义一个新数组:
$menu = array();
foreach($res as  $key $value){
     $menu[$value['name']]['name'] = $value['name'];
     $menu[$value['name']]['icon'] = $value['icon'];
     $menu[$value['name']]['class'][$value['menu_id']] = $value['menu_url'];
     $menu[$value['name']]['class'][$value['menu_id']] = $value['menu_ch_name'];
     $menu = array_values($menu);

        echo'<pre>'; 
        print_r($menu); 
        echo'</pre>';
}
