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"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf8"> <title>Insert title here</title> </head> <body bgcolor="#ccc"> <form name="article" method="post" action="articlePublishDo.php"> <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> </html>
articlePublishDo.php：
<"content-type:text/html;charset=utf8"); date_default_timezone_set('Asia/Shanghai'); $title=trim($_POST['title']); $content=trim($_POST['content']); $time=date("y-m-d H:i:s"); 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>'; }else{ echo "发布失败"; echo '<a href="articleList.php">返回文章列表</a>'; } mysql_close();//关闭数据库

init.php：
<?php //连接数据库 //五步走 //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。
