实用好用的PHP分页类代码与使用

类的代码如下：

total = $_total ? $_total : 1;???		$this->pagesize = $_pagesize;??		$this->pagenum = ceil($this->total / $this->pagesize);???		$this->page = $this->setPage();???		$this->limit = "LIMIT ".($this->page-1)*$this->pagesize.",$this->pagesize";???		$this->url = $this->setUrl();???		$this->bothnum = 2;??	}????	//拦截器??	private function __get($_key) {???		return $this->$_key;??	}????	//获取当前页码??	private function setPage() {???		if (!empty($_GET['page'])) {????			if ($_GET['page'] > 0) {?????				if ($_GET['page'] > $this->pagenum) {??????					return $this->pagenum;?????				} else {??????					return $_GET['page'];?????				}????			} else {?????				return 1;????			}???		} else {????			return 1;???		}??	}?????	//获取地址??	private function setUrl() {???		$_url = $_SERVER["REQUEST_URI"];???		$_par = parse_url($_url);???		if (isset($_par['query'])) {????			parse_str($_par['query'],$_query);????			unset($_query['page']);????			$_url = $_par['path'].'?'.http_build_query($_query);???		}???		return $_url;??	}??	//数字目录??	private function pageList() {???		for ($i=$this->bothnum;$i>=1;$i--) {????		$_page = $this->page-$i;????		if ($_page url.'&page='.$_page.'">'.$_page.' ';???		}???		$_pagelist .= ' '.$this->page.' ';???		for ($i=1;$ibothnum;$i++) {???	?		$_page = $this->page+$i;????			if ($_page > $this->pagenum) break;????			$_pagelist .= ' '.$_page.' ';???		}???		return $_pagelist;??	}????	//首页  http://ini.iteye.com/??	private function first() {???		if ($this->page > $this->bothnum+1) {????			return ' 1 ...';???		}??	}????	//上一页??	private function prev() {???		if ($this->page == 1) {????			return '上一页';???		}???		return ' 上一页 ';??	}????	//下一页??	private function next() {???		if ($this->page == $this->pagenum) {????			return '下一页';???		}???		return ' 下一页 ';??	}????	//尾页??	private function last() {???		if ($this->pagenum - $this->page > $this->bothnum) {????			return ' ...'.$this->pagenum.' ';???		}??	}????	//分页信息??	public function showpage() {???		$_page .= $this->first();???		$_page .= $this->pageList();???		$_page .= $this->last();???		$_page .= $this->prev();???		$_page .= $this->next();???		return $_page;??	}?}?>
