php留言板问题???谁能和我说下
这个留言板算是一个系统,步骤该怎样进行??不知该怎样下手。。
------解决方案--------------------
做一个前台页面通过get一个值来判定操作类型,比如?do=ly这样就显示表单,如果没有参数就显示所有留言列表,在就是后台做一一个接受post值得处理文件,在就是做一些基本的安全过滤和规则判定,就直接入库存起来, 就这样啊,呵呵

------解决方案--------------------
我给一个楼主我的思路吧:
1、需求分析:楼主想要的留言版是否需要验证用户,是否需要安全性高...。
2、数据库设计:通过分析楼主的需求确定需要哪些表和字段。
3、html页面设计,通过需求分析确定要几个页面,及需要的样式,如果要求高这一步可以提前。
4、书写php代码,通过需求分析,确定需要的具体功能,然后书写指定的代码。
5、测试程序可用性,修改bug。
写这个程序的前提是要看楼主具体的需求,可简单可复杂。我的回答完毕,希望对楼主有帮助。
------解决方案--------------------
一个“留言板”应该具有如下功能:
1、他提供一个输入表单,为了用户写下意见文字。(append)
2、他提供一个留言列表,为了用户查看已存在的留言。(browse)
3、他提供一个管理表单,为了管理员删除已存在的留言。(manage)
这就是编写一个“留言板”的基本分析方法,也就是“留言板”类(boand)所应有的基本方法
无论你使用文件还是数据库来保存“留言板”的数据,都需要有一个标志数据来源的变量供类的方法使用。这就是属性
你的“留言板”类可能会被用于不同的目的,因此就可能需要用标识用途的属性headline(标题);为了展现不同的风格,你又可能需要属性style
总之,无论你的“留言板”以什么样的界面展现给用户,用何种媒体存放数据。其基本的方法都是要存在的

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
