本文章给各位php入门者提供一篇从数据库的创建到最后的读写留言板过程全部分享给各位朋友,有需要了解的可参考参考.

创建一个数据表实例代码如下:

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 ;
Copy after login

数据库连接文件数据库连接的代码比较固定.先新建一个conn.php文件,输入下面代码:

实例代码如下:

<?php
$conn = mysql_connect("localhost", "root", "") or die("数据库链接错误");
mysql_select_db("test", $conn);
mysql_query("set names &#39;GBK&#39;"); //使用GBK中文编码;
?>
Copy after login

编写发表留言页面文件新建文件add.php,输入如下代码:

实例代码如下:

<?php
include ("conn.php");
if ($_POST[&#39;submit&#39;]) {
    $sql = "insert into message (id,user,title,content,lastdate) values (&#39;&#39;,&#39;$_POST[user]&#39;,&#39;$_POST[biaoti]&#39;,&#39;$_POST[content]&#39;,now())";
    mysql_query($sql);
    echo "成功发表!";
}
?>
</table> 
<br /> 
<h2>发表留言框</h2> 
<form action="add.php" method="post" >
Copy after login

用户:

<input type="text" name="user" size="10" /><br />
Copy after login

标题:

<input type="text" name="biaoti" size="20" /><br /> 
<textarea name="content" rows="10" cols="50" wrap="off"> 
</textarea><br /> 
<input type="submit" name="submit" value="发表"/> 
</form>
Copy after login

编写留言列表文件新建文件list.php,输入如下代码:

实例代码如下:

<?php
include ("conn.php");
?> 
<table width="500px" border="0" alien="center" > 
<?php
$sql = "select * from message ";
$query = mysql_query($sql);
while ($row = mysql_fetch_array($query)) { ?>
    <tr><td>标题: <?php
    echo $row[&#39;title&#39;]; ?>用户:<?php
    echo $row[&#39;user&#39;]; ?></td></tr> 
    <tr><td>发表内容:<?php
    echo $row[&#39;content&#39;]; ?></td></tr> 
    <?php
} ?>
</table>
Copy after login
