Judging by your screen name, I presume you are a foreigner of some sort unfamiliar with the English language. Possibly Indian, from the sounds of the screen name. I might be wrong.
In truth, I dont even understand your question. You want to know what the difference is by reversing the order of the words?
Nothing. Its just a linguistic quirk. Whether its spoken one way or the other is likely due to dialect and context, but has no affect on meaning.
