這篇文章主要介紹了php實(shí)現(xiàn)的后臺(tái)表格分頁(yè)功能,涉及php針對(duì)數(shù)據(jù)庫(kù)的連接、查詢、刪除、動(dòng)態(tài)生成表格等相關(guān)操作技巧,需要的朋友可以參考下

本文實(shí)例講述了php實(shí)現(xiàn)的后臺(tái)表格分頁(yè)功能。分享給大家供大家參考，具體如下：

<?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
  //用戶管理
  echo "用戶管理<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 || $result1 === false) {
    echo "執(zhí)行失敗";
  }else {
    //$rowcount = mysqli_affected_rows($conn);
    $arr = mysqli_fetch_all($result,1);
    $rowcount = count($arr);
    echo "查詢到的結(jié)果行數(shù)：" . $rowcount . "<br/>";
    //if($rowcount > 0){
      $arr1 = mysqli_fetch_all($result1,1);
      $count = count($arr1);
      echo "總行數(shù)：$count<br/>";
?>
<table border="1">
  <tr>
    <td>用戶編號(hào)</td>
    <td>用戶名</td>
    <td>密碼</td>
    <td>郵箱</td>
    <td>電話</td>
    <td>操作</td>
  </tr>
<?php
  for($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=".$tmp."'>刪除</a></td>
      </tr>
    ";
   }
?>
</table>
<?php
}
?>
<!-- 傳值 AJAX可優(yōu)化 -->
<a href="user.php?start=0" rel="external nofollow" >首頁(yè)</a>
<a href="user.php?start=<?php if($start>=3)echo $start-3; else echo $start; ?>" rel="external nofollow" >上頁(yè)</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 $start+3; ?>" rel="external nofollow" >下頁(yè)</a>
<a href="user.php?start=<?php if($count%3==1)echo $count-1; elseif($count%3==2) echo $count-2; elseif($count%3==0) echo $count-3; ?>" rel="external nofollow" >尾頁(yè)</a>
<span>第<?php echo $start/$pagecount+1 ?>頁(yè)|共<?php $tmp=$count/$pagecount; $tmp1=(int)($count/$pagecount); if($tmp>$tmp1) echo $tmp1+1; else echo $tmp1; ?>頁(yè)</span>

delete.php：

<?php
  //刪除用戶
  echo "刪除用戶<br/>";
  @$uid = $_REQUEST['uid'];
  if($uid === null || $uid === " "){  //這里注意，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 "執(zhí)行失敗";
  }else{
    $count = mysqli_affected_rows($conn);
    if($count > 0){
      echo "用戶刪除成功";
      $result1= mysqli_query($conn,$sql1);
      if($result1 === false){
        echo "重排序失敗";
      }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?jiǎng)h除的用戶不存在";
    }
  }
?>

注：

（1）用AJAX可以實(shí)現(xiàn)傳值優(yōu)化，提升性能，這里沒(méi)有實(shí)現(xiàn)；

（2）下一頁(yè)那邊還沒(méi)有一些bug，不能到最后一頁(yè)停止，后續(xù)再實(shí)現(xiàn)吧。

希望本文所述對(duì)大家PHP程序設(shè)計(jì)有所幫助。
