php 页面分页样式 示例

  1 <?php

  3 
  4     private $each_disNums; //每页显示的条目数
  5     private $nums; //总条目数
  6     private $current_page; //当前被选中的页
  7     private $sub_pages; //每次显示的页数
  8     private $pageNums; //总页数
  9     private $page_array = array(); //用来构造分页的数组
 10     private $subPage_link; //每个分页的链接
 11     private $subPage_type; //显示分页的类型
 12 
 13     /*
 14       construct是SubPages的构造函数,用来在创建类的时候自动运行.
 15       @$each_disNums   每页显示的条目数  自定义一个变量赋值为页数:$page = 2;
 16       @nums     总条目数  (统计表中要查找的记录数)
 17       @current_num     当前被选中的页(在subpage_link这个参数中传输一个值:Messageshow.php?cur_page=,在接收页面接收)
 18       @sub_pages       每次显示的页数(每次显示的页数=总条目数/每页显示的条目数)
 19       @subPage_link    每个分页的链接(显示这些记录的页面)
 20       @subPage_type    显示分页的类型
 21       当@subPage_type=1的时候为普通分页模式
 22       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]
 23       当@subPage_type=2的时候为经典分页样式
 24       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]
