初学php，对于api的认识为0，查询了一些资料，还是不太理解，求各位大神用简单易懂的言语把api的事说一下吧，小弟在此跪谢。

api接口
API(Application Programming Interface,应用程序编程接口)是一些预先定义的函数，目的是提供应用程序与开发人员基于某软件或硬件的以访问一组例程的能力，而又无需访问源码，或理解内部工作机制的细节。API除了有应用“应用程序接口”的意思外，还特指 API的说明文档，也称为帮助文档。

这些看过了，不过我没写过，我主要的问题是：我如何定义一个自己的api，或者说我要定义一个自己的api 大概分为哪些步骤呢？
既然你需要提供 API 给人家使用，那么就需要规划好：
调用方式：function、XML-RPC、REST、web service、.....
如果是 function 方式，还需要在用户方安装支撑库
参数格式：包括传入、传出数据的组织形式
显然所有的 API 都应遵守同一规则
具体的实现，就是你的事情了
说白了php的api有2种，一个是copy代码装进自己的项目，通过某种语法规则直接调用，但会直接暴露代码；还有一种是像访问网页那样提交一些参数后直接获得结果，但这需要对方打开服务器。
