我初学php和mysql,模仿php100视频教程做一个留言板发布网站,但点击“留言“按钮后总是弹出“留言失败!”,同时数据库中也没有导入信息,求大神看一下哪出代码出问题了,谢谢!
数据库 名称:test_liuyanban
表 名称:message
字段:int(主键)、username(用户名)、email(邮箱)、content(留言内容)。
一共两个文件:conn.php和index.php
conn.php:
$conn = @mysql_connect('localhost','root','12345')or die('连接失败!');
@mysql_select_db("test_liuyanban")or die('没有该数据库!');
mysql_query("set names 'GBK'");
?>
index.php:
include_once'conn.php';
if($_POST['post']){
$sql="insert into `message` (id,username,email,content) values ('','$_POST[username]','$_POST[email]','$_POST[content]')";
$result=mysql_query($sql);
if($result){
echo"<script>alert('留言成功!');location.href='index.php'</script>";
}else{
echo"<script>alert('留言失败!');location.href='index.php'</script>";
}
}
?>

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
