Pager.class.php 代码如下

  1. class Pager {

  166.         $this->arithmetic();
  167.         return $this->pageStyle ();
  168.     }
  169. }

调用代码(test.php 代码如下)

  1. include_once 'Pager.class.php';
  2. $pager=new Pager();
  3. if (isset ( $_GET ['page'] ) && ! emptyempty ( $_GET ['page'] ))
  4.     $pager->setCurrentPage($_GET ['page']);
  5. else
  6.     $pager->setCurrentPage(1);
  7.     
  8. $pager->setRecorbTotal(1000);
  9. $pager->setBaseUri("test.php?");
  10. echo $pager->execute();

 

数据库结合 mysql 通用存储过程分页 海量数据分页  就是一个完美的分页了

 

我们还可继承 Pager 类重写pageStyle方法就可以有不同的样式了. yes ok
