I am developing an app in Android, i need get information from a external database in mysql and i read about Rest..

REST is using HTTP verbs GET, POST, PUT, DELETE to respectively get, insert, update, delete resources on a server. E.g. GET with url: controller/customer/{id}

But why not use a simple Php ? is really necessary to use REST?

i dont understand why i must use Rest if a simple PHP will do the same.

Rest with php is a RESTFul?

I dont think you understand the terminologies correctly. PHP is a programming language. REST is a method of interacting with remote servers. You cant replace REST with PHP because they are two different things. Are you really asking why REST vs a plain HTTP request? –  GrandmasterB Dec 6 '13 at 19:00
"Rest with php is a RESTFul?" This question made me laugh. –  stimpy77 Dec 6 '13 at 19:04
@stimpy77: I never found working in PHP restful. It usually made me wish I could take a break and rest... ;) –  FrustratedWithFormsDesigner Dec 6 '13 at 19:12
Are you asking this because you think REST is a programming language like PHP or are you asking because you can't see why you would want to GET /customer/{ID} instead of using CGI arguments like /customer.php?id={ID} ? –  Sean McSomething Dec 6 '13 at 19:12

PHP is a programming language.

REST refers to architectural guides for building web services.

The decision to use PHP and the decision to create a REST-based web service are completely independent of each other. RESTful services can be implemented in Java, C#, PHP, Ruby, any language you can run on a server. PHP can be used to write a program that calls RESTful services developed by other people - if someone else chooses to build a service that you need to use and it is RESTful, you may not have much choice in how you interact with it, even if you personally don't like REST.
