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.'
