<?php
/**
* 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。
* 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,
* example:
* 模式四种分页模式：
* require_once(../libs/classes/page.class.php);
* $page=new page(array(total=>1000,perpage=>20));
* echo mode:1<br>.$page->show();
* echo <hr>mode:2<br>.$page->show(2);
* echo <hr>mode:3<br>.$page->show(3);
* echo <hr>mode:4<br>.$page->show(4);
* 开启ajax：
* $ajaxpage=new page(array(total=>1000,perpage=>20,ajax=>ajax_page,page_name=>test));
* echo mode:1<br>.$ajaxpage->show();
