PHP实现简单的新闻发布系统实例

本文实例讲述了PHP实现简单的新闻发布系统。分享给大家供大家参考。具体如下：

本人小白，一直在公司用模板和框架写PHP，发现有时候连基本的sql语句都忘记了，所以有空想把PHP基础复习下，巩固下。分页和搜索，以及排序，还没写，后期继续更新...（代码修改：添加搜索和分页功能）

articlePublish.html：

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html lang="en">

<title>Insert title here</title>
</head>
<body bgcolor="#ccc">
 <form name="article" method="post" action="articlePublishDo.php" style="margin:5px 500px;">
   <h1>发布新闻系统</h1>
  标题：<input type="text" name="title"/><br/>
  内容：<textarea cols=30 rows=5 name="content"></textarea><br/><br/>
   <input type="submit" value="发布新闻"/>
 </form>
</body>

articlePublishDo.php：

 require_once 'init.php';
 $sql="insert into article(title,content,create_time) values('$title','$content','$time')";
 //echo $sql;
 $re=mysql_query($sql);//执行sql语句
 if($re){
  echo "发布成功";
  echo '<a href="articleList.php">返回文章列表</a>';

 //往数据库添加文章
 $conn=mysql_connect("localhost","root","");//链接数据库
 //echo $conn;
 $re=mysql_select_db("article");//选择数据库
 mysql_query("set names utf8");//设置交互字符集

基础知识总结：

文章发布系统

1.articlePublish.html 发布文章页面 提交到articlePublishDo.php页面,执行写入数据库

2.articleList.php 文章列表页面

3.点击编辑,修改文章 提交到 aiticleEdit.php 表单页面（回显）

4.点击修改文章按钮 提交到 articleUpdate.php

希望本文所述对大家的php程序设计有所帮助。
