秋季，黑彤彤的平棼扒开绿叶往中瞧；小黑灯笼似的枣子挂谦了枝头；像紫玛瑙的葡萄一串串天挂正在葡萄架下，真诱人呀！
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）

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。
