如何利用后台来发布文章后,在前台显示

怎么利用后台来发布文章后,在前台显示。
每次手工在前台写代码 来添加文章,实在很麻烦,也很累人。我想在后台写个功能,输入标题,内容 就可以直接发表。  我想利用文件读取。然后利用正则来读取php文件的某个位置,然后添加文章,比如
我想在index.php显示文章。而index.php的内容为

<br /><div style="float: left;height: 2%;padding-top: 1%;padding-left: 232px;padding-bottom: 4%;"><h1 id="文章作者-文章标题-文章时间">文章作者——————————————文章标题—————————————文章时间</h1><hr></div><br /><table class="article"><br /><div><br /><tr><br /><th width="100"><a style="font-size:18px;text-decoration:none;" href="www.baidu.com">Black-Hole</a></th><br /><td><br /><a style="padding-left: 273px;" href="http://www.baidu.com">PHP代码</a><br /></td><br /><td><br /><a style="padding-left:25%;" href="http://www.baidu.com">2014年2月28号</a><br /></td><br /></tr><br /></div>
Copy after login

我先在后台写个标题 内容 作者 时间。点击发布文章后,在写个正则读取index.php里的article">与
之间的内容。擦除内容,写入我刚刚写的 标题 内容 作者 时间。

这样又可以保证新帖子永远在第一位。又省去手工写代码来添加文章的麻烦。

因为 本人学php不到1年。所以,又很多地方不懂,望各位程序员照顾下新人,谢谢了
------解决方案--------------------
这是很基础的东西。
需要用到数据库,可以查看mysql 的dbconnect,select,insert,update,delete语法。
写了个demo,可以插入数据库,从数据库中按时间倒序显示记录,希望对你有帮助。

dbname是 demo

连接数据库
[email protected]_connect("localhost","root","") or die(mysql_error());
@mysql_select_db('demo',$conn) or die(mysql_error());

localhost 是服务器ip,本机用localhost
root是数据库用户名
密码为空。

db结构
<br />CREATE TABLE `test` (<br />  `id` int(10) unsigned NOT NULL auto_increment,<br />  `name` varchar(100) NOT NULL,<br />  `age` tinyint(4) unsigned NOT NULL,<br />  `addtime` datetime NOT NULL,<br />  PRIMARY KEY  (`id`)<br />) ENGINE=MyISAM  DEFAULT CHARSET=latin1 AUTO_INCREMENT=3 ;<br />
Copy after login


db.php 用于显示记录
<br /><?php<br /><br />	//打开数据库<br />	function opendb(){<br />		[email&#160;protected]_connect("localhost","root","")  or die(mysql_error());<br />		@mysql_select_db('demo',$conn) or die(mysql_error());	<br />	}<br /><br />	//关闭数据库<br />	function closedb(){<br />		@mysql_close() or die("關閉數據庫出錯!");<br />	}<br /><br />    opendb();<br /><br />    echo '<meta http-equiv="content-type" content="text/html; charset=utf-8">';<br /><br />    $sqlstr = "select * from test order by addtime desc";<br />    $query = mysql_query($sqlstr) or die(mysql_error());<br /><br />    while($thread=mysql_fetch_assoc($query)){<br />        $result[] = $thread;<br />    }<br /><br />    if($result){<br />        foreach($result as $val){<br />            echo $val['id'].' '.$val['name'].' '.$val['age'].' '.$val['addtime'].'<br>';<br />        }<br />    }<br /><br />?><br />
Copy after login


add.php 用于新增记录

<br><?php <br /><br>//打开数据库<br>function opendb(){<br>    [email protected]_connect("localhost","root","")  or die(mysql_error());<br>    @mysql_select_db('demo',$conn) or die(mysql_error());	<br>}<br><br>//关闭数据库<br>function closedb(){<br>    @mysql_close() or die("關閉數據庫出錯!");<br>}<br><br>opendb();<br><br><br>$send = isset($_POST['send'])? $_POST['send'] : '';<br><br>if($send=='true'){ // submit<br><br>    $name = isset($_POST['name'])? $_POST['name'] : ''; <br>    $age = isset($_POST['age'])? $_POST['age'] : '';<br>    $addtime = date('Y-m-d H:i:s');<br><br>    if($name=='' <br><font color="#FF8000">------解决方案--------------------</font><br> $age==''){<br>        exit('name or age is empty');<br>    }<br><br>    $sqlstr = "insert into test(name,age,addtime) values('{$name}','{$age}','{$addtime}')";<br>    mysql_query($sqlstr) or die(mysql_error());<br><br>    echo 'insert success';<br><br>}else{<br><br>?><br>nbsp;HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><br><br> <br>  <meta><br>  <title> New Document </title><br>  <meta><br> <br><br> <br>

The relationship between mysql user and database The relationship between mysql user and database Apr 08, 2025 pm 07:15 PM

In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.

RDS MySQL integration with Redshift zero ETL RDS MySQL integration with Redshift zero ETL Apr 08, 2025 pm 07:06 PM

Data Integration Simplification: AmazonRDSMySQL and Redshift's zero ETL integration Efficient data integration is at the heart of a data-driven organization. Traditional ETL (extract, convert, load) processes are complex and time-consuming, especially when integrating databases (such as AmazonRDSMySQL) with data warehouses (such as Redshift). However, AWS provides zero ETL integration solutions that have completely changed this situation, providing a simplified, near-real-time solution for data migration from RDSMySQL to Redshift. This article will dive into RDSMySQL zero ETL integration with Redshift, explaining how it works and the advantages it brings to data engineers and developers.

Do mysql need to pay Do mysql need to pay Apr 08, 2025 pm 05:36 PM

MySQL has a free community version and a paid enterprise version. The community version can be used and modified for free, but the support is limited and is suitable for applications with low stability requirements and strong technical capabilities. The Enterprise Edition provides comprehensive commercial support for applications that require a stable, reliable, high-performance database and willing to pay for support. Factors considered when choosing a version include application criticality, budgeting, and technical skills. There is no perfect option, only the most suitable option, and you need to choose carefully according to the specific situation.

How to optimize MySQL performance for high-load applications? How to optimize MySQL performance for high-load applications? Apr 08, 2025 pm 06:03 PM

MySQL database performance optimization guide In resource-intensive applications, MySQL database plays a crucial role and is responsible for managing massive transactions. However, as the scale of application expands, database performance bottlenecks often become a constraint. This article will explore a series of effective MySQL performance optimization strategies to ensure that your application remains efficient and responsive under high loads. We will combine actual cases to explain in-depth key technologies such as indexing, query optimization, database design and caching. 1. Database architecture design and optimized database architecture is the cornerstone of MySQL performance optimization. Here are some core principles: Selecting the right data type and selecting the smallest data type that meets the needs can not only save storage space, but also improve data processing speed.

How to fill in mysql username and password How to fill in mysql username and password Apr 08, 2025 pm 07:09 PM

To fill in the MySQL username and password: 1. Determine the username and password; 2. Connect to the database; 3. Use the username and password to execute queries and commands.

Query optimization in MySQL is essential for improving database performance, especially when dealing with large data sets Query optimization in MySQL is essential for improving database performance, especially when dealing with large data sets Apr 08, 2025 pm 07:12 PM

1. Use the correct index to speed up data retrieval by reducing the amount of data scanned select*frommployeeswherelast_name='smith'; if you look up a column of a table multiple times, create an index for that column. If you or your app needs data from multiple columns according to the criteria, create a composite index 2. Avoid select * only those required columns, if you select all unwanted columns, this will only consume more server memory and cause the server to slow down at high load or frequency times For example, your table contains columns such as created_at and updated_at and timestamps, and then avoid selecting * because they do not require inefficient query se

Understand ACID properties: The pillars of a reliable database Understand ACID properties: The pillars of a reliable database Apr 08, 2025 pm 06:33 PM

Detailed explanation of database ACID attributes ACID attributes are a set of rules to ensure the reliability and consistency of database transactions. They define how database systems handle transactions, and ensure data integrity and accuracy even in case of system crashes, power interruptions, or multiple users concurrent access. ACID Attribute Overview Atomicity: A transaction is regarded as an indivisible unit. Any part fails, the entire transaction is rolled back, and the database does not retain any changes. For example, if a bank transfer is deducted from one account but not increased to another, the entire operation is revoked. begintransaction; updateaccountssetbalance=balance-100wh
