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

									}

									?>
