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
<?php
namespace page;

.pagination{

padding:20px 0px;
}
.pagination a{
display:block;
float:left;
margin-right:10px;
padding:2px 12px;
height:24px;
border:1px #cccccc solid;
background:#fff;
text-decoration:none;

line-height:24px;
}

}
.pagination p.pageRemark b{

}
.pagination p.pageEllipsis{
border-style:none;

color:#808080;
}
.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,
],
