再看thinkphp5分页类使用

 /**
     * 分页查询
     * @access public
     * @param  int|array $listRows 每页数量 数组表示配置参数
     * @param  int|bool  $simple   是否简洁模式或者总记录数
     * @param  array     $config   配置参数
     *                            page:当前页,
     *                            path:url路径,
     *                            query:url额外参数,
     *                            fragment:url锚点,
     *                            var_page:分页变量,
     *                            list_rows:每页数量
     *                            type:分页类名
     * @return \think\Paginator
