本文实例讲述了php实现的后台表格分页功能。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 || $result1 === false) {
 echo "执行失败";
 }else {
 //$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：$count<br/>";
?>
<table border="1">
 <tr>
 <td>用户编号</td>
 <td>用户名</td>
 <td>密码</td>
 <td>邮箱</td>
 <td>电话</td>
 <td>操作</td>
 </tr>
<?php
 for($i=0;$i<count($arr);$i++){
 $tmp = $arr[$i]['uid'];
 echo "
 <tr>
 <td>".$arr[$i]['uid']."</td>
 <td>".$arr[$i]['uname']."</td>

<!-- 传值 AJAX可优化 -->
<a href="user.php?start=0" rel="external nofollow" >首页</a>
<a href="user.php?start=<?php if($start>=3)echo $start-3; else echo $start; ?>" rel="external nofollow" >上页</a>

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 "执行失败";
 }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。
