简单的利用php谢了一个分页的功能模块，php分页功能模块

先贴张图看看效果

在贴一下代码吧

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'] ? $_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 "
PHP分页代码的小模块
";
    echo "

"; echo ""; while($row = mysql_fetch_assoc($result)){ $id = $row['id']; $name = $row['name']; echo ""; } echo "

ID	NAME
".$id."	".$name."

"; //上一页 、下一页 $pageprev = $page -1 ; if($page > $total){ $pagenext = $total; } else{ $pagenext = $page +1; } // 做链接 跳转； echo "

上一页 丨下一页

"; mysql_free_result($result); mysql_close($conn); ?>

关键点： 1、$sql = "select * from page order by id limit {$offset},{$pagesize}";

　　　　 2、echo "

上一页 丨下一页

";
