关于PHP的函数
各位大大们,晚安.小弟在理解的过程中遇到这一组函数,没办法理清是怎么达到的
这个函数是来自一个游戏的类似发送游戏道具至邮件的一个功能
因小弟因特殊要求需要把此函数用于ASP VB另作开发
所以想理清这个功能是怎么形成的.

想请问这是以什么方式进行达到
如若小弟有遗漏函数,大大们可以指出 我可以提供相关文件代码.
感激不尽.
在线等待. 第一个主要只是一个分支，流程控制，
第二个就是一个发送 POST 的，发送的是 XML 他这里复杂化了。
向 http://58.254.217.74:6001/PostBulletin 发送了一个 POST 请求，
待发送的数据
cuttle=8002&parm0=50054&parm1=7340036
计算签名，即拼接上密钥 malimalihong，并进行 md5 处理
sign = md5("cuttle=8002&parm0=50054&parm1=7340036malimalihong")
这里 sign 计算出来的结果是 faa6b12356d3d5f9da7e8fe13f54e7db
最终就是向 http://58.254.217.74:6001/PostBulletin 发送了一个数据，内容是 cuttle=8002&parm0=50054&parm1=7340036&sign=faa6b12356d3d5f9da7e8fe13f54e7db ，
最终收到结果
这个 58.254.217.74:6001 目前连不上~
