i want a class which has no errors and works fine ,for calling any twitter functions as mentioned like here–http://sources.disruptive-innovations.com/twitterHelper/tags/latest/TwitterHelper.html#mozTocId93000
You can’t find a library like the one you linked to – it uses basic auth which doesn’t exist any more.
Working with the API is a bit of an undertaking. Have you looked at the documentation on this site yet?
