共享一个php分页类
一个php的分页类，自我感觉相当不错，看源码就已经知道这款php的分页类有多么强大了，基本上涵盖了php分页的所有功能，里面的方法不少，值得新手朋友学习一下了,而在制作php应用中，php的分页技术也是不可缺少的，看看这款吧~
使用时需要先将其保存成为一个类文件，然后进行实例化调用方可使用。
PHP代码
class Pageination
{
var $perPage; //当前页
var $perLimit; //当前每页显示条数
var $perPageLimit; //当前每页显示页数
var $totalNums; //当前分页中的总条数
var $totalPage; //当前分页中总页数
var $pageUrl; //定义当前网页路径
var $pageBaseUrl; //定义当前网页根路径
var $pageStart; //定义当前开始末ID
var $pageEnd; //定义当前结束ID
var $pageHeader; //定义显示头部分
var $pageBody; //定义显示主体部分
var $pageBottom; //定义显示尾部分
var $imgInfo; //定义当前分页时所需图标
var $pageStyle; //定义当前分页样式
var $pageInfo; //定认当前分页信息
var $pageAction; //定认当前分页点击执行回叫函数
var $htmlPage=""; //是否静态页分页
var $limitMaxPage; //最多分页数
