Paging is implemented under the thinkphp framework. The company's website is based on the Thinkphp framework. I have been hearing about thinkphp for a long time and finally had the opportunity to put it into practice. thinkphp is based on MVC architecture. MVC is familiar to any ITers, model-view-controller. It handles logic and data separately, eliminating a lot of tedious processes. In fact, the official information has introduced in detail how to paginate, portal: http://document.thinkphp.cn/manual_3_2.html#data_page

However, it does not apply to the case where the data has been taken out from the DB and converted into an array. I have been exposed to PHP for a full 2 months, and I have been exposed to thinkphp for only 3 weeks. I spent a lot of time on official documents to get familiar with thinkphp. It can be regarded as a worker who sharpens his sword and chops firewood. The official document is explained here as a comparison:
(only the first method in the document is cited): Using the Page class and the limit method, the code is as follows:

<span $User</span> = M('User'); <span //</span><span  实例化User对象</span>
<span $count</span>= <span $User</span>->where('status=1')-><span count</span>();<span //</span><span  查询满足要求的总记录数</span>
<span $Page</span> = <span new</span> \Think\Page(<span $count</span>,25);<span //</span><span  实例化分页类 传入总记录数和每页显示的记录数(25)</span>
<span $show</span> = <span $Page</span>->show();<span //</span><span  分页显示输出
// 进行分页数据查询 注意limit方法的参数要使用Page类的属性</span>
<span $list</span> = <span $User</span>->where('status=1')->order('create_time')->limit(<span $Page</span>->firstRow.','.<span $Page</span>->listRows)-><span select();
</span><span $this</span>->assign('list',<span $list</span>);<span //</span><span  赋值数据集</span>
<span $this</span>->assign('page',<span $show</span>);<span //</span><span  赋值分页输出</span>
<span $this</span>->display(); <span //</span><span  输出模板</span>

The function array_slice( ) that comes with PHP is used. The definition is here: http://www.php.net/manual/en/function.array-slice.php
is actually the array version of the limit method. Well, now that the tool is found, implementation is easy. Directly upload the code:

<span public</span> <span function</span><span  nodeslist(){
</span><span $portal</span> = <span new</span><span  PortalApi;
</span><span $nodelist</span> = <span $portal</span>->getNodeLists(<span $this</span>-><span uid);

</span><span $count</span> = <span count</span>(<span $nodelist</span>['data'<span ]);
</span><span $p</span> = <span new</span> Page(<span $count</span>,10<span );
</span><span $lists</span> = <span array_slice</span>(<span $nodelist</span>['data'], <span $p</span>->firstRow,<span $p</span>-><span listRows);
</span><span $page</span> = <span $p</span>-><span show();
</span><span $this</span>->assign('page',<span $page</span><span );
</span><span $this</span>->assign('nodes',<span $lists</span><span );
</span><span $this</span>-><span display(); 
}</span>

The getNodeLists method in line 3 retrieves data from the database and assigns it to the array nodelist.
Line 5 count calculates the number of array elements.
Line 6 passes in parameters to the Page class.
The array_slice function on line 7 replaces the limit method. The principle is the same.
Line 9 uses the assign method to assign a value to the template. The definition is here: http://document.thinkphp.cn/manual_3_2.html#assign
The same applies to line 10.

Code in view:

<div <span class</span>="page-list"><span 
{</span><span $page</span><span }
</span></div>
