mysqli_query($conn,$sql);

$pagecount = 3;

?>

<?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>

<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" 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>

<a href="user.php?start=3" rel="external nofollow" >2</a>

<a href="user.php?start=6" rel="external nofollow" >3</a>

<a href="user.php?start=9" rel="external nofollow" >4</a>

<a href="user.php?start=12" rel="external nofollow" >5</a>

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。

希望本文所述对大家PHP程序设计有所帮助。
