PHP+HTML简单实现BBS论坛与回帖
本文主要讲述如何通过PHP+HTML简单实现BBS论坛和发帖/回帖的功能,这是提取我们php项目的部分内容。主要内容包括:
1.通过JavaScript和Iframe实现局部布局界面
2.PHP如何定义类实现访问数据库功能
3.实现简单的BBS论坛和发帖/回帖功能
由于这个项目是十个人在寒假完成,所以采用了SAE搭建在线的后台数据库,其他人在通过Apache本地设计网页、访问数据库的方法实现,相当于简单的BS三端访问。

一. 首页布局搭建
首先是搭建首页的布局,主要布局分为head、main_left和main_right。其中右边显示部分采用的是iframe实现的局部显示,而左边采用JavaScript实现点击隐藏和显示功能。其中index.php首页代码如下:
