$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 "

";

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~

以上所述就是本文给大家分享的全部内容了,希望大家能够喜欢。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
