本文实例讲述了php实现后台表格分页功能分享给大家供大家参考,具体如下:

<?php //init.php $conn = mysqli_connect('127.0.0.1','root','','xz',3306); $sql = "SET NAMES UTF8"; mysqli_query($conn,$sql); $pagecount = 3; ?>

user.php:

<?php //用户管理 echo "用户管理<br/>"; @$start = $_REQUEST['start']; if($start === null || $start === " "){ die("start required"); } require("init.php"); $sql = "SELECT * FROM xz_user LIMIT $start,$pagecount"; $sql1 = "SELECT uid FROM xz_user"; $result = mysqli_query($conn,$sql); $result1 = mysqli_query($conn,$sql1); if($result === false || $result1 === false) { echo "履行失败"; }else { //$rowcount = mysqli_affected_rows($conn); $arr = mysqli_fetch_all($result,1); $rowcount = count($arr); echo "查询到的结果行数:" . $rowcount . "<br/>"; //if($rowcount > 0){ $arr1 = mysqli_fetch_all($result1,1); $count = count($arr1); echo "总行数:$count<br/>"; ?> <table> <tr> <td>用户编号</td> <td>用户名</td> <td>密码</td> <td>邮箱</td> <td>电话</td> <td>操作</td> </tr> <?php for($i=0;$i<count($arr);$i++){ $tmp = $arr[$i]['uid']; echo " <tr> <td>".$arr[$i]['uid']."</td> <td>".$arr[$i]['uname']."</td> <td>".$arr[$i]['upwd']."</td> <td>".$arr[$i]['email']."</td> <td>".$arr[$i]['phone']."</td> <td><a href='delete.php?uid=".$tmp."'>删除</a></td> </tr> "; } ?> </table> <?php } ?> <!-- 传值 AJAX可优化 --> <a href="user.php?start=0" >首页</a> <a href="user.php?start=<?php if($start>=3)echo $start-3; else echo $start; ?>" >上页</a> <a href="user.php?start=3" >2</a> <a href="user.php?start=6" >3</a> <a href="user.php?start=9" >4</a> <a href="user.php?start=12" >5</a> <a href="user.php?start=15" >6</a> <a href="user.php?start=<?php echo $start+3; ?>" >下页</a> <a href="user.php?start=<?php if($count%3==1)echo $count-1; elseif($count%3==2) echo $count-2; elseif($count%3==0) echo $count-3; ?>" >尾页</a> <span>第<?php echo $start/$pagecount+1 ?>页|共<?php $tmp=$count/$pagecount; $tmp1=(int)($count/$pagecount); if($tmp>$tmp1) echo $tmp1+1; else echo $tmp1; ?>页</span>

delete.php:

<?php //删除用户 echo "删除用户<br/>"; @$uid = $_REQUEST['uid']; if($uid === null || $uid === " "){ //这里注意,是|| die("uid required"); } require('init.php'); $sql = "DELETE FROM xz_user WHERE uid='$uid'"; $sql1 = "UPDATE xz_user SET uid=uid-1 WHERE uid > '$uid'"; $result = mysqli_query($conn,$sql); if($result === false){ echo "履行失败"; }else{ $count = mysqli_affected_rows($conn); if($count > 0){ echo "用户删除成功"; $result1= mysqli_query($conn,$sql1); if($result1 === false){ echo "重排序失败"; }else{ echo "重排序成功"; } if($uid % $pagecount == 0) Header("Location:user.php?start=$uid"); if($uid % $pagecount == 1){ $uid -= 1; Header("Location:user.php?start=$uid"); } if($uid % $pagecount == 2){ $uid -= 2; Header("Location:user.php?start=$uid"); } }else{ echo "要删除的用户不存在"; } } ?>

注:

(1)用AJAX可以实现传值优化,提升性能,,这里没有实现;

(2)下一页那边还没有一些bug,不能到最后一页停止,后续再实现吧。
