简单,方便,功能全的php分页类

分页类代码<br>
<?php

class


SubPages{

private $each_disNums;

//每页显示的条目数

private $nums;

//总条目数

private $current_page;

//当前被选中的页

private $sub_pages;

//每次显示的页数

private $pageNums;

//总页数

private $page_array = array();

//用来构造分页的数组

private $subPage_link;

//每个分页的链接

private $subPage_type;

//显示分页的类型

/*

__construct是SubPages的构造函数，用来在创建类的时候自动运行.

@$each_disNums   每页显示的条目数

@nums     总条目数

@current_num     当前被选中的页

@sub_pages       每次显示的页数

@subPage_link    每个分页的链接

@subPage_type    显示分页的类型

当@subPage_type=1的时候为普通分页模式

example：   共4523条记录,每页显示10条,当前第1/453页 [首页] [上页] [下页] [尾页]

当@subPage_type=2的时候为经典分页样式

example：   当前第1/453页 [首页] [上页] 1 2 3 4 5 6 7 8 9 10 [下页] [尾页]
