PHP分頁導覽 php通用分頁工具類實現

1.先上圖，看下實現效果

2、整類實作

	private $total;			//总数量
	private $limit;			//返回mysql的limit语句
	private $pageStart;		//开始的数值
	private $pageStop;		//结束的数值
	private $pageNumber;	//显示分页数字的数量
	private $page;			//当前页
	private $pageSize;		//每页显示的数量
	private $pageToatl;		//分页的总数量
	private $pageParam;		//分页变量
	private $uri;			//URL参数
	/**
	 * 分页设置样式 不区分大小写
	 * %pageToatl%  //总页数
	 * %page%		//当前页
	 * %pageSize% 	//当前页显示数据条数

	 * %pageStop%	//本页结束条数
	 * %total%		//总数据条数
	 * %first%		//首页
	 * %ending%		//尾页
	 * %up%			//上一页
	 * %down%		//下一页
	 * %F%			//起始页
	 * %E%			//结束页
	 * %omitFA%		//前省略加跳转
	 * %omitEA%		//后省略加跳转
	 * %omitF%		//前省略
	 * %omitE%		//后省略
	 * %numberF%	//固定数量的数字分页
	 * %numberD%	//左右对等的数字分页
	 * %input%		//跳转输入框
	 * %GoTo%			//跳转按钮
