thinkphp如何实现分页

public function faculty()
    {
        //查询院系专业信息
        //--查询院系专业信息
        $result=Db::name('sys_faculty')->field('*')->paginate(10,false,[
            'query'=>['user'=>'123','role'=>'student']
        ])->each(function($item, $key){
            //在这里对查询的值进行进一步的整理！！！
           $f_faculty=Db::name('sys_faculty')->field('name')->where('id',$item['parentid'])->find();
           $item['faculty']=$f_faculty['name'];
           //如果是Db类操作分页数据的话，each方法的闭包函数中需要使用返回值
           return $item;
        });
        $this->assign(['result'  => $result]);
        return $this->fetch();
    }

<style>
       .page_li{
        }
        .page_li li{
            display:inline-block;
            padding:0px 10px;
        }
        .page_li li a{
            display:inline-block;
            padding:0px 4px;
            color:#0088CC;
            font-size:small;
        }
        .page_li li.active{
            color:red;
            font-size:large;
        }
    </style>

<style>
       /*分页*/
       .pagination {}
       .pagination li {
           display: inline-block;
           margin-right: -1px;
           padding: 5px;
           border: 1px solid #e2e2e2;
           min-width: 20px;
           text-align: center;
       }
       .pagination li.active {
           background: #009688;
           color: #fff;
           border: 1px solid #009688;
       }
       .pagination li a {
           display: block;
           text-align: center;
       }
    </style>
