Hi All, I am new to ruby and i want to develop an web service in ruby that will be invoked by the PHP application and will return the output to the PHP variable. Please suggest me how i should proceed in terms of learning ruby and developing my web service. Any help or suggestion would be greatly appreciated. Thanks Gaurav

Well, there are several different ways you could get your PHP front-end to call your Ruby web service, such as: * REST (HTTP GET / POST / PUT / DELETE, usually with XML parameters) * SOAP * xmlrpc I'm afraid I don't know which of these has the easiest or most robust PHP client support. However I personally wouldn't choose SOAP unless it was forced on me, as it's a horrendously complex beast. (It's fine as long as the APIs are hiding the complexity; the problem is debugging it when it isn't working) For the Ruby backend, there are a variety of web frameworks out there that you can consider. If you're learning from scratch I'd suggest Rails, primarily because there are plenty of excellent books you can buy. I have the PragProg.com books: "Agile Web D. with Rails" and "The Ruby P.ming Language" (*) and they suit me very well, but there are plenty of others to choose from. Rails supports REST natively, and SOAP as a plugin. However, Rails is big so there's a lot to learn, and a lot of HTML-generation functionality may be irrelevant to you initially. For a really simple REST backend you could consider Sinatra, as you can write apps which are just a handful of lines of code. You'll need to add a database access layer of your choice - e.g. ActiveRecord from Rails, or Sequel or Datamapper. Again, if you choose ActiveRecord then you'll find lots of Rails books with good coverage. If you want to use xmlrpc then there is a simple xmlrpc server included in the Ruby standard library. This should be fine under small loads, but it may not scale as well as other solutions (since it's based on WEBrick, and as far as I know it doesn't give you the options of using mongrel / thin / rack / phusion passenger etc.) Of course, once you've learned Ruby, you may find you want to ditch PHP for the front-end and use Ruby there too :-) BTW a similar question was asked here about 3 days ago, so have a look at that too: http://www.ruby-forum.com/topic/175849 Good luck, Brian. (*) The old, first edition of the Programming Ruby book (for ruby-1.6) is available for free on-line: http://www.ruby-doc.org/docs/ProgrammingRuby/ This is a good starting point before you decide to invest in a newer book.
