通过实例讲解php如何实现列表分页功能

先贴张图看看效果

在贴一下代码吧

<?php
 $localhost = "localhost";
 $username = "root";
 $password = "root";
 $db = "test";   //信息
 $pagesize = 5;
 $conn = mysql_connect($localhost,$username,$password); //链接数据库
  if(!$conn){
   echo "数据库链接失败".mysql_error();
  }
 mysql_query("SET NAMES &#39;UTF8&#39;"); //编码转化
 $db_select = mysql_select_db($db); //选择表
          //查询记录总数
 $total_sql = "select COUNT(*) from page";
 $total_result = mysql_query($total_sql);
 $total_row_arr = mysql_fetch_row($total_result);
 $total_row = $total_row_arr[0];   //总条数
 //总页数
 $total = ceil($total_row / $pagesize);
 //当前页数
 $page = @$_GET[&#39;p&#39;] ? $_GET[&#39;p&#39;] : 1;
  //limit 下限
 $offset = ($page - 1)*$pagesize;
 
 $sql = "select * from page order by id limit {$offset},{$pagesize}";
 $result = mysql_query($sql);
 echo "<p>PHP分页代码的小模块</p>";
 echo "<table border=1 cellspacing=0 WIDTH=60% align=center>";
 echo "<tr><td>ID</td><td>NAME</td></tr>";
 while($row = mysql_fetch_assoc($result)){
  $id = $row[&#39;id&#39;];
  $name = $row[&#39;name&#39;];
  echo "<tr><td>".$id."</td><td>".$name."</td></tr>";
 }
 echo "</table>";
 //上一页 、下一页
 $pageprev = $page -1 ;
  if($page > $total){
   $pagenext = $total;
  } else{
   $pagenext = $page +1;
  }
 // 做链接 跳转;
 echo "<h3> <a href=&#39;page.php?p={$pageprev}&#39;>上一页</a> 丨<a href=&#39;page.php?p={$pagenext}&#39;>下一页</a></h3>";
 
 mysql_free_result($result);
 mysql_close($conn);
?>
Copy after login

关键点:

$sql = "select * from page order by id limit {$offset},{$pagesize}";
Copy after login

代码如下:

 echo "<h3> <a href=&#39;page.php?p={$pageprev}&#39;>上一页</a> 丨<a href=&#39;page.php?p={$pagenext}&#39;>下一页</a></h3>";
Copy after login

这两点是关键能体现 分页技术 和php 代码艺术的地方~
