IP地址
这个想法一两年前就有了,不过当时几位朋友在谈话中觉得IP地址搜索这种东西早已做滥了,没有必要再做,所以把这个想法搁置在一边。但是一两年过去了,现在还是常常无法找到好的IP地址数据库,觉得这个想法还是值得一试,反正写这样一个程序也不费事。
现在的IP地址分配是由电信这些网络运营商来做的,他们没有公布子网分配的信息,所以现在搜集IP地址信息只有从民间发起,这是个艰巨的工作,IP子网实在是太多了,而且IP地址本身也会变化,造成已经收集的IP地址信息过时,另外还有一个信息真实性的问题。所有这些会产生巨大的工作量,靠人工来实现是很麻烦的事情,特别是在没有报酬的情况下去维护这样一批数据使人望而却步。
在我的设想中,这个IP地址搜索引擎会是这样的:
- 提供和普通的IP地址搜索一样的搜索框(最最普通的)
- 在页面上显示你的当前IP地址信息,如果没有找到或者错误,可以通过链接来提交正确的信息
- 提供IP地址数据库下载,但是在下载之前必须提交你的当前IP地址信息
- 所有来自用户提交的IP地址信息提交至临时数据库内
- 如果有n条临时数据库内的IP地址信息表明某子网属于同一地区,并且在正式数据库内的对应子网地址信息错误或者不存在,则提交进入正式数据库内
每个人都可以来无偿的获取这里的IP地址数据库,但是必须以自己当前的IP地址信息作为回报
将来自不同用户的IP地址信息进行对比来判断信息的真实性,这个机制还有一些细节需要考虑,不过基本上我已经想好了,其实主要是防止某些心理不健康的人恶意的提交大量虚假信息欺骗系统,另外这种机制也节约大量人工,让数据自行增长
长期的用户IP地址信息提交保持IP地址信息不过时
这种机制的成功与否取决于用户使用数量是否达到一个基数,如果人多,提交的信息多,这个IP地址数据库就会越来越好,进入良性循环。
近期把这个东西写出来,早期的IP地址数据库只有从网上现有的来了。

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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
