实用好用的PHP分页类代码与使用
<?phpclass 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 name="code"><?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.?>
