实用好用的PHP分页类代码与使用

类的代码如下：

<?php	class Page {??		private $total;??? 	//总记录??		private $pagesize;??	//每页显示多少条??		private $limit;???		//limit??		private $page;???		//当前页码??		private $pagenum;?		//总页码??		private $url;????		//地址??		private $bothnum;?		//两边保持数字分页的量????	//构造方法初始化??	public function __construct($_total, $_pagesize) {???		$this->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 < 1) continue;????			$_pagelist .= ' <a href="'.$this->url.'&page='.$_page.'">'.$_page.'</a> ';???		}???		$_pagelist .= ' <span class="me">'.$this->page.'</span> ';???		for ($i=1;$i<=$this->bothnum;$i++) {???	?		$_page = $this->page+$i;????			if ($_page > $this->pagenum) break;????			$_pagelist .= ' <a href="'.$this->url.'&page='.$_page.'">'.$_page.'</a> ';???		}???		return $_pagelist;??	}????	//首页  http://ini.iteye.com/??	private function first() {???		if ($this->page > $this->bothnum+1) {????			return ' <a href="'.$this->url.'">1</a> ...';???		}??	}????	//上一页??	private function prev() {???		if ($this->page == 1) {????			return '<span class="disabled">上一页</span>';???		}???		return ' <a href="'.$this->url.'&page='.($this->page-1).'">上一页</a> ';??	}????	//下一页??	private function next() {???		if ($this->page == $this->pagenum) {????			return '<span class="disabled">下一页</span>';???		}???		return ' <a href="'.$this->url.'&page='.($this->page+1).'">下一页</a> ';??	}????	//尾页??	private function last() {???		if ($this->pagenum - $this->page > $this->bothnum) {????			return ' ...<a href="'.$this->url.'&page='.$this->pagenum.'">'.$this->pagenum.'</a> ';???		}??	}????	//分页信息??	public function showpage() {???		$_page .= $this->first();???		$_page .= $this->pageList();???		$_page .= $this->last();???		$_page .= $this->prev();???		$_page .= $this->next();???		return $_page;??	}?}?>

??使用说明：

<?php	$_page = new Page($_total,$_pagesize); //其中 $_total 是数据集的总条数,$_pagesize 是每页显示的数量.?>

?分页样式如下图所示：?
