$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 "

上一页下一页

";

 

mysql_free_result($result);

mysql_close($conn);

?>

关键点:

1、

?

1

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

     2、

 

 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~
