Let me share with you another one that is mainly used for novices to learn PHP paging. The code is simple and practical, and the comments are complete.

1. Page.class.php

<&#63;php
/**
 * 分页类
 * 
 * 调用方式:
 * $p=new Page(总页数,显示页数,当前页码,每页显示条数,[链接]);
 * print_r($p->getPages()); //生成一个页码数组(键为页码,值为链接)
 * echo $p->showPages(1); //生成一个页码样式(可添加自定义样式)
 *

/*
思路:
给我一个 总页数,需要显示的页数,当前页,每页显示的条数,连接
写一个方法 生成一个一维数组,键为页码 值为连接
写一个方法 返回一个生成好样式的页码(并且可以根据自己需要添加样式)
默认样式 共45条记录,每页显示10条,当前第1/4页 [首页] [上页] [1] [2] [3] .. [下页] [尾页]
