Best way to implement a Rest API with PHP on WAMP web server

I own a web server running Windows (WAMP). I want to know the best way to implement a Rest API (a very simple one) in order to let a user do something.

I have programming skills, in fact, I developed a web server in VB6 who process the queries and when it finds the command (http:/serverIP/webform.php?cmd=run&item=any) it does something, but I really want to develop a solution using the WAMP server.

Some people consider the solution of executing a exe when a command is detected a bad solution for security issues, but this specific project I have is for the use by some people (trusted people) who dont have intentions of hacking the server.

So, what do you think?

Rem开发者_开发技巧ember:

1. Its not a public API, its for some people and some programs who will use the API
2. Its a very simple one, only one command using POST or GET.

Ive just recently finished a REST API project on PHP and it was a good experience. The way I see it, the fastest/easiest way to implement this is using the following elements:

• Object Oriented PHP
• MVC paradigm
• Create a request dispatcher

I found this link very useful when I started, it should get you going in no time:

Edit:

I didnt use this framework but it looked promising: http://tonic.sourceforge.net/

Also, CakePHP supports Rest and is a neat MVC framework. If you're looking to implement in no time, go with CakePHP.

Good luck!
