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：

<Meta http-equiv="Content-Type" content="text/html; charset=utf8"> Insert title here PHP" style="margin:5px 500px;">

articleUpdate.PHP：

init.PHP：

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。
