分享php分页的功能模块,php分页功能模块

先贴张图看看效果

在贴一下代码吧

<&#63;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 'UTF8'"); //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['p'] &#63; $_GET['p'] : 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['id'];
  $name = $row['name'];
  echo "<tr><td>".$id."</td><td>".$name."</td></tr>";
 }
 echo "</table>";
 //上一页 、下一页
 $pageprev = $page -1 ;
  if($page > $total){
   $pagenext = $total;
  } else{
   $pagenext = $page +1;
  }
 // 做链接 跳转;
 echo "<h3 id="a-href-page-php-p-pageprev-上一页-a-丨-a-href-page-php-p-pagenext-下一页-a"> <a href='page.php&#63;p={$pageprev}'>上一页</a> 丨<a href='page.php&#63;p={$pagenext}'>下一页</a></h3>";
 
 mysql_free_result($result);
 mysql_close($conn);
&#63;>

关键点:

               1、

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

     2、

复制代码 代码如下: echo "

上一页下一页

";

这两点是关键能体现 分页技术 和php 代码艺术的地方~
