漂亮的 PHP 驗證碼類

  class Page {
 private $total; //總記錄
 private $pagesize; //每頁顯示多少條
 private $limit; //limit
 private $page; //目前頁碼
 private $pagenum; //總頁碼
 private $url; //位址
 private $bothnum; //兩邊保持數字分頁的量

 //建構方法初始化
 public function __construct($_total, $_pagesize) {
 $this->total = $_total ? $_total : 1;
 $this->total = $_total ? $_total : 1; 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;
 }

 //取得目前頁碼
 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;
 }
 }

 //取得位址
 private function setUrl() {
 $_url = $_SERVER["REQUEST_URI"];
 $_par = parse_url($_url);
 if (Yisset($par_url); ['query'])) {
 parse_str($_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  $_pagelist . = ' '.$_page.' ';
 }
 $_pagelist .= ' '.$this->page.' ';
 for ($i=1;$ibothnum;$i ) {
 $_page = $this->page $i;
 if ($_page > $this->pagenum) break;
 $_pagelist .= ' '.$_page.' ';
 }
 return $_pagelist;
 }

 //首頁
 private function first() {
 if ($this->page > $this->bothnum 1) {
 return ' 1 . ..';
 }
 }

 //上一頁
 private function prev() {
 if ($this->page == 1) {
 return '上一頁';
 }
 return ' 上一頁 ';
 }

 //下一頁
 private function next() {
 if ($this- >page == $this->pagenum) {
 return '下一頁';
 }
 return ' 下一頁 ';
 }

 //尾頁
 private function last() {
 if ($this->pagenum - $this->page > $this->bothnum) {
 return ' .. .'.$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;
 }
 }
 ?>

分頁樣式如下圖：

使用說明：

  $_page = new Page($_total,$_pagesize); //其中$_total 是資料集的總條數,$_pagesize 是每頁顯示的數量.
 ?>
