<?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 //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。
希望本文所述对大家PHP程序设计有所帮助。
