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"

<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" 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>

 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

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。
