php实现的后台表格分页功能示例
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>
<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>
<a href="user.php?start=15" rel="external nofollow" >6</a>
<a href="user.php?start=<?php echo $start+3; ?>" rel="external nofollow" >下页</a>
<a href="user.php?start=<?php if($count%3==1)echo $count-1; elseif($count%3==2) echo $count-2; elseif($count%3==0) echo $count-3; ?>" rel="external nofollow" >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 "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。
