这篇文章主要介绍了PHP实现简单的新闻发布系统,涉及php实现新闻发布系统的sql查询、插入、更新等完整操作技巧,具有一定参考借鉴价值,需要的朋友可以参考下。
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)

- 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。
