简单,方便,功能全的php分页类

<br>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

[email protected]_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]

[email protected]_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]
