實用好用的PHP分頁類代碼與使用

類的代碼如下：

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;??}????//攔截器??private function __get($_key) {???return $this->$_key;??}????//擷取當前頁碼??private function setPage() {???if (!empty($_GET['page'])) {????if ($_GET['page'] > 0) {?????if ($_GET['page'] > $this->pagenum) {??????return $this->pagenum;?????} else {??????return $_GET['page'];?????}????} else {?????return 1;????}???} else {????return 1;???}??}?????//擷取地址??private function setUrl() {???$_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 $_url;??}??//數字目錄??private function pageList() {???for ($i=$this->bothnum;$i>=1;$i--) {????$_page = $this->page-$i;????if ($_page < 1) continue;????$_pagelist .= ' url.'&page='.$_page.'">'.$_page.' ';???}???$_pagelist .= ' '.$this->page.' ';???for ($i=1;$i<=$this->bothnum;$i++) {????$_page = $this->page+$i;????if ($_page > $this->pagenum) break;????$_pagelist .= ' url.'&page='.$_page.'">'.$_page.' ';???}???return $_pagelist;??}????//首頁  http://ini.iteye.com/??private function first() {???if ($this->page > $this->bothnum+1) {????return ' url.'">1 ...';???}??}????//上一頁??private function prev() {???if ($this->page == 1) {????return '上一頁';???}???return ' url.'&page='.($this->page-1).'">上一頁 ';??}????//下一頁??private function next() {???if ($this->page == $this->pagenum) {????return '下一頁';???}???return ' url.'&page='.($this->page+1).'">下一頁 ';??}????//尾頁??private function last() {???if ($this->pagenum - $this->page > $this->bothnum) {????return ' ...url.'&page='.$this->pagenum.'">'.$this->pagenum.' ';???}??}????//分頁資訊??public function showpage() {???$_page .= $this->first();???$_page .= $this->pageList();???$_page .= $this->last();???$_page .= $this->prev();???$_page .= $this->next();???return $_page;??}?}?>
