求个具体的php+mysql分页-不用网上搜的

class page{
	private $_page_num;//总页数
	private $_page_size=10;//每页条数
	private $_page_url;//url链接
	private $_limit;//limit1
	private $_page_total;//总分页数
	private $_page;//分页所传分页值
	private $_list_size=10;//这为第二种分页方法显示条数
	private $_page_sort=3;//分页两边距离
	public function __construct($_total,$_pagesize,$_list_size){
		$this->_page_size=$_pagesize;
		$this->_page_total=$_total;
		$this->_list_size = $_list_size;
		$this->_page_num = round($this->_page_total/$this->_page_size);
		$this->_page=$this->getnum();
		$this->_limit="limit".$this->_page*$this->_page_size.",".$this->_page_total=$_total;
		$this->_page_url=$this->seturl();
	}
	/**
	 * 获取当前页数
	 * Enter description here ...
	 */
	private function getnum(){
		if(isset($_GET['page'])){
			if(is_numeric($_GET['page'])){
				if($_GET['page']>0){
					if(ceil($_GET['page'])>=1 && ceil($_GET['page'])<=$this->_page_num){
						return ceil($_GET['page']);
					}elseif(ceil($_GET['page'])>$this->_page_num){
						return $this->_page_num;
					}
				}else{
					return 1;
				}
			}else{
				return 1;
			}
		}else{
			return 1;
		}
	}
	/**
	 * 转换链接
	 * Enter description here ...
	 */
	private function seturl(){
		$_url=$_SERVER['REQUEST_URI'];//获取请求地址
		$_par=parse_url($_url);//解析url
		if(isset($_par['query'])){//判断是否存在aa=bb这种格式
			$_url=parse_str($_par['query'],$_query);//重构url
			unset($_query['page']);
			$_url=$_par['path'].'?'.http_build_query($_query);
		}else{
			$_url=$_url.'?';
		}
		return $_url;
	}
	
	public function limit(){
		return $this->_limit;
	}
	
	public function pagenum(){
		return $this->_page_num;
	}

	public function page(){

	}
	private function pagelist_1(){

		for($i=1;$i<=$this->_page_num;$i++){
			 $_page.="".$i."";
