This article provides PHP beginners with an article to share the entire process from the creation of the database to the final reading and writing of the message board with friends. If you need to know more, you can refer to it.

Create a data table

The code is as follows

Copy code

代码如下

复制代码

CREATE TABLE `message` (

`id` tinyint(1) NOT NULL auto_increment,

`user` varchar(25) NOT NULL,

`title` varchar(50) NOT NULL,

`content` tinytext NOT NULL,

`lastdate` date NOT NULL,

PRIMARY KEY (`id`)

) ENGINE=InnoDB DEFAULT CHARSET=gbk AUTO_INCREMENT=1 ;

CREATE TABLE `message` (

`id` tinyint(1) NOT NULL auto_increment,

`user` varchar(25) NOT NULL,

`title` varchar(50) NOT NULL,

代码如下

复制代码

$conn = mysql_connect("localhost", "root", "") or die("数据库链接错误");

mysql_select_db("test", $conn);

mysql_query("set names ‘GBK'"); //使用GBK中文编码;

`content` tinytext NOT NULL,
`lastdate` date NOT NULL,

PRIMARY KEY (`id`)

代码如下

复制代码

include("conn.php");

if($_POST['submit']){

$sql="insert into message (id,user,title,content,lastdate) values (",'$_POST[user]‘,'$_POST[biaoti]‘,'$_POST[content]‘,now())";

mysql_query($sql);

echo "成功发表！";

}

The code for database connection is relatively fixed. First create a new conn.php file and enter the following code:

The code is as follows	Copy code
<🎜>$conn = mysql_connect("localhost", "root", "") or die("Database link error");<🎜> <🎜>mysql_select_db("test", $conn);<🎜> <🎜>mysql_query("set names ‘GBK'"); //Use GBK Chinese encoding;<🎜> <🎜>?>

Write a message page file Create a new file add.php and enter the following code:

The code is as follows	Copy code
<🎜>include("conn.php");<🎜> <🎜>if($_POST['submit']){<🎜> <🎜>$sql="insert into message (id,user,title,content,lastdate) values (",'$_POST[user]','$_POST[biaoti]','$_POST[content]',now ())";<🎜> <🎜>mysql_query($sql);<🎜> <🎜>echo "Published successfully!";<🎜> <🎜>}<🎜> <🎜>?>

Post a message box

Write message list file Create a new file list.php and enter the following code:

The code is as follows

Copy code

<🎜>include ("conn.php");<🎜> <🎜>?> <🎜>$sql="select * from message ";<🎜> <🎜>$query=mysql_query($sql);<🎜> <🎜>while($row=mysql_fetch_array($query)){ ?>
