最详细的ThinkPHP5自定义分页类教程

作为一名PHP程序员在编写列表性质的页面时，几乎都要写上一段分页的程序。分页的方法有很多种，本文我们就给大家详细介绍一下ThinkPHP5自定义分页类教程。

第一步：创建文件Page.php,将其放到extend\page,这里也可以自己决定，命名空间对了就行

            }
            .dates li {font-size: 14px;margin:20px 0}
            .dates li span{float:right}
        </style>';
    }
}

第二步：修改配置文件

//分页配置  
   'paginate'               => [  
       'type'      => 'page\Page',//分页类  
       'var_page'  => 'page',  
       'list_rows' => 15,  
   ],
