PHP 分页类,可以集成到框架内

pagenum = ceil($count/$pagesize);
		$this->pagesize = $pagesize;
		$this->page =(isset($_GET['p'])&&$_GET['p']>0) ? intval($_GET['p']) : 1;
	}
	/**
	 * 获得 url 后面GET传递的参数
	 */ 
	public function getUrl(){   
		$url = 'index.php?'.http_build_query($_GET);
		$url = preg_replace('/[?,&]p=(\w)+/','',$url);
		$url .= (strpos($url,"?") === false) ? '?' : '&';
		return $url;
	}
	/**
	 * 获得分页HTML
	 */
	public function getPage(){
		$url = $this->getUrl();
		$start = $this->page-5;
		$start=$start>0 ? $start : 1; 
		$end   = $start+9;
		$end = $endpagenum ? $end : $this->pagenum;
		$pagestr = '';
		if($this->page>5){
			$pagestr = "首页 ";
		}
		if($this->page!=1){
			$pagestr.= "上一页";
		}
		
		for($i=$start;$ipage!=$this->pagenum){
			$pagestr.="下一页";
			
		}
		if($this->page+5pagenum){
			$pagestr.="尾页 ";
		}
		return $pagestr;	
	}
	
}
// 测试代码
$page = new page(100,10);
$str=$page->getPage();
echo $str;
