Are you working with multiple devices like iPhone, Android and Web then take a look at this post that explains you how to develop a RESTful API in PHP.  Representational state transfer (REST) is a software system for distributing the data to different kind of applications. The web service system produce status code response in JSON or XML format.

Difference between SOAP and REST in Web services- 1. REST has no WSDL interface definition 2. REST is over HTTP, but SOAP can be over any transport protocols such HTTP, FTP, STMP, JMS etc. 3. SOAP is using soap envelope, but REST is just XML.

Q) What is differnce between loosely coupling and tightly coupling?

Ans: Coupling generally refers to the act of joining two things together, such as the links in a chain. But in software development, coupling typically refers to the degree to which software components/modules depend upon each other. The degree to which components are linked defines whether they operate in a tightly coupled relationship or in a loosely coupled relationship. With tightly coupled components, each component and any auxiliary dependent objects must be present at execution time as well as compile time. On the other hand, loosely coupled components can operate independently from one another.
