本文執行個體講述了PHP分頁顯示的方法。分享給大家供大家參考，具體如下：
<?phpheader("content-type:text/html;charset=utf-8");$currentpage = 1;if(isset($_GET['page'])) $currentpage = $_GET['page'];//串連資料庫$link = mysql_connect("localhost","root","") or die('串連失敗');mysql_select_db('myschool');mysql_query('set names utf8');$sql ="SELECT count(*) as 'count' from student";//查詢記錄的sql語句$result = mysql_query($sql);$arr = mysql_fetch_array($result);$count = $arr['count'];$pagesize = 3;$pages = ceil($count/$pagesize);//共多少頁$prepage = $currentpage -1;if($prepage<=0) $prepage=1;$nextpage = $currentpage+1;if($nextpage >= $pages){ $nextpage = $pages;}$start =($currentpage-1) * $pagesize;//起始位置$sql = "SELECT * from student limit $start,$pagesize";echo $sql;// $sql = "select * from student";$result = mysql_query($sql);?><!-- html部分 --><!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>Document</title></head><body><table border="1"> <tr> <td>學號</td> <td>姓名</td> <td>性別</td> <td>年齡</td> </tr><?php while($arr=mysql_fetch_array($result)){ ?> <td><?php echo $arr['number']; ?></td> <td><?php echo $arr['name']; ?></td> <td><?php echo $arr['sex']; ?></td> <td><?php echo $arr['age']; ?></td> </tr><?php } ?> </table> <a href="<?php echo $_SERVER['PHP_SELF'].'?page='.$prepage; ?>" rel="external nofollow" >上一頁</a> <a href="<?php echo $_SERVER['PHP_SELF'].'?page='.$nextpage; ?>" rel="external nofollow" >下一頁</a></body></html>
註：當一個檔案中有php和html兩種時，php檔案必須有結束標記
附：php通用分頁類與用法：
Page.class.php檔案：
<?php/** * 分頁類 * * 調用方式： * $p=new Page(總條數,顯示頁數,當前頁碼,每頁顯示條數,[連結]); * print_r($p->getPages()); //產生一個頁碼數組（鍵為頁碼，值為連結） * echo $p->showPages(1); //產生一個頁碼樣式（可添加自訂樣式） * *//*總條數，需要顯示的頁數，當前頁，每頁顯示的條數，串連產生一個一維數組，鍵為頁碼 值為串連返回一個產生好樣式的頁碼（並且可以根據自己需要添加樣式）預設樣式 共45條記錄,每頁顯示10條,當前第1/4頁 [首頁] [上頁] [1] [2] [3] ..

用法樣本demo.php：
<?php/** * demo */header("content-type:text/html;charset=utf8");include('Page.class.php'); //引入類//$p=new Page(總條數,顯示頁數,當前頁碼,每頁顯示條數,[連結]);//串連不設定則為當前連結$page=isset($_GET['page']) ? $_GET['page'] : 1;$p=new Page(100,4,$page,8);//產生一個頁碼數組（鍵為頁碼，值為連結）echo "<pre>";print_r($p->getPages());//樣式 共45條記錄,每頁顯示10條,當前第1/4頁 [首頁] [上頁] [1] [2] [3] ..
