PHP的bbs实现之一的相关文章

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

BBS练手JSP系统完成

今天上午,把学习马士兵的BBS系统完事了.本系统主要采用ECLIPSE下WEB项目的开发,JSP,MYSQL,JSP,CSS,JS,html等技术.制作了8个JSP文件,完成了递归(帖子的父子级别).分页.前台后台.树形展现.平板型展现.回复帖子.新建帖子.后台能够管理帖子.删除帖子等操作.   项目可以运行,我将项目源码上传至CSDN,地址如下:   http://download.csdn.net/detail/opzoonzhuzhengke/3881662   下午要做天气预报的文档和部

深度分析:BBS习惯与blog及digg的冲突

BBS习惯与blog及digg的冲突 谁迁就谁? 1顶---BBS里有"顶",我觉得这个"顶"从内涵上要好过digg的"顶",形式上digg的更华丽,为什么这么说呢? 在bbs里的"顶"除了有发布的列表头的功能,它还贡献了内容,而digg只是表达了"好恶".发布到列表头是一种"功利性"的需求,而贡献内容则是自我实现.所以从这个方面来说,我觉得digg是有点哗众取宠. 2列表---BBS玩

基于MySQL的BBS设计(1)

1.系统架构: 采用模块化思想,分为3层: a.数据存储层:使用mysql来存放bbs的所有数据,包括用户信息,文章数据,用户信件,用户消息,系统数据(?),关键问题: 数据库的规划,是否用文件来辅助. b.系统功能层:完成bbs的基本功能,由多个并列模块组成,向下调用mysql的函数访问数据库,向上,接受处理请求,将处理的结果返回上层,根据请求类型,返回成败结果和其他数据.而且模块高度灵活,可以方便的修改增加.包括: ** 用户模块,处理用户的注册,基本数据的修改,权限的变化,网友信息的查询.

使用XML实现BBS

xml <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />  表A: 1-0-1,this is a test 3-1-1,this is a test 4-3-1,this is a test 5-3-1,this is a test 2-0-2,this is a test 上面是BBS主题列表的一个例子.一般来说,假如不是使用Oracle(Oracle 有一条查询语句

ASP:用ASP打造一个小型的网页BBS系统

传统的网页BBS大多是采用CGI模式实现的,它的实现要求编程者既要掌握编程语言如Perl或C等,又要了解关于CGI模式的各项技术内容,因此要制作自己的网页BBS确实困难不小.ASP(Active Server Pages 动态服务器主页)的出现,使我们眼前一亮,能不能利用ASP实现网页BBS呢?回答当然是肯定的.ASP的诱人之处就在于它提供了一种简单易学的脚本,并带有许多内置的对象,从而提供了一条简捷的编程之路. 该BBS主要由用户注册(浏览器端).用户注册(服务器端).加帖子(浏览器端).加帖

搜索引擎与BBS的母体世界的进化

互联网诞生后的20年中,它的虚拟空间里宛如混沌的宇宙漂浮着若干个简单而又核心的应用,他们分别是电子邮件,FTP,电子公告牌,原始的网络游戏.其中电子公告牌在80年代以后成为互联网诸多创新应用的母体.BBS的各个功能逐渐分离出去成为雄踞一方的霸主.我们先看一下这个母体九个儿子的分离情况(并不以分离时间排序):  第一个:新闻网站是BBS发布新闻功能的演化,这个功能最为简单而且最受用户关注,它应该是BBS踏上独立发展的第一个儿子. 第二个:电子商务是BBS发布供需信息功能的演化.它在演化过程中逐渐与

应对BBS风暴 中小论坛的几条出路

2007年政策突然变化让国内众多BBS措手不及,因为个人申报论坛成功性极低,所以国内大部分中小型论坛面临关闭的危险,对空间服务商和BBS程序开发商将产生较大冲击.建议个人论坛可以考虑以下几个出路: 1.关闭论坛改建网站.这给建站开发商CMS带来无限商机,CMS开发商只要提供帖子转文章的程序,把论坛帖子和图片按对应关系一一转到CMS的文章系统,这将会给CMS带来无限商机! 2.流到国外.利用国外空间建论坛.但是在国外搭论坛速度慢,主要受到出口带宽的限制 3.联合建坛的,个人论坛联合在一起组建公司申
