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]
