1、 网络留言板的设计与实现 【摘要】设计并实现了一个基于 B/S 架构的网络留言板。该留言板系统采用 PHP 技术开发，利用数据库访问技 术实现对数据库的各种操作，从而实现了留言板的留言及管理功能。在设计过程中遵循软件开发流程，首先对系统 功能作出需求分析，在此基础上建立系统的应用原型，然后进行了留言板系统的功能设计与实现，经过测试阶段的 反复调试和验证不断地修正和完善系统功能，最终达到符合要求的可行系统。实现的具体功能包括用户注册、留言 查看、留言签写、留言搜索及后台管理等，并根据不同功能模块面向的用户对权限进行了合理划分。 【关键词】留言板；PHP；数据库；MySQL Design and
2、Implementation of Message Boards Abstract: A internet message board based on B / S structure is designed and implemented. The message board system is developed with the PHP language, makes use of the database access technology for database operations, in order to achieve the leaving words function a
3、nd management function. Following the software development processes during the design process, first of all the requirement analysis is made for the system. Based on this the system application prototype is established, and then the functions of the message board system are designed and implemented
4、, after repeated debug and commissioning, the system function is improved continuously, eventually the requirements of practical system is reached. Its specific functions include user registration, message viewing, writing message, message searching and the background management. According to the different functional modules, the permission of the users is divided rationally.
