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:

 }

init.php:

<"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。
