title: What should be returned from web service instead of datatable?
body: <p>I have created a web service in which i need to return multiple records from a function. For that I used datatable, but found that as it cannot be serialized. So we can't use it. So I used dataset instead of datatable. 
  My service is going to be used in PHP. I am not sure that they (PHP developers) will be able to get data from my dataset (returned from my webservice's function) or not.</p>
  
  <p>Please suggest me what I should return. Dataset or is there any other better option available?</p>
  
  <p>Thanks.</p>
