11. * description:超强分页类，四种分页模式，默认采用类似baidu,google的分页风格。
    
12. * 2.0增加功能：支持自定义风格，自定义样式，同时支持PHP4和PHP5,
    
13. * to see detail,please visit http://www.phpobject.net/blog/read.php
    
14. * example:
    
15. * 模式四种分页模式：
    
16.    require_once('../libs/classes/page.class.php');
    
17.    $page=new page(array('total'=>1000,'perpage'=>20));
    
18.    echo 'mode:1<br>'.$page->show();
    
19.    echo '<hr>mode:2<br>'.$page->show(2);
    
20.    echo '<hr>mode:3<br>'.$page->show(3);
    
21.    echo '<hr>mode:4<br>'.$page->show(4);
    
22.    开启AJAX：
    
23.    $ajaxpage=new page(array('total'=>1000,'perpage'=>20,'ajax'=>'ajax_page','page_name'=>'test'));
    
24.    echo 'mode:1<br>'.$ajaxpage->show();
    
25.    采用继承自定义分页显示模式：
