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>
