are there APIs to get some statistics from twitter

I have a task to create a dynamic page (PHP or Javascript) that shows:

1. Number of tweets with specific hash tag
2. Number of tweets that came from specific country!!
3. most popular hash-tags for specific country

does anybody have any idea of how to get su开发者_StackOverflow中文版ch stats or part of them??

Thanks a lot for your help

Yes, but you should really search more because there's a lot of information out there on this - start at the Twitter API Docs.

1. You use it as a search term
2. Try https://dev.twitter.com/docs/places/finding-tweets-about-places
3. Combine 1. & 2.

No. Twitter releases its statistics after a certain period of time. There's no definitive/official API for that. But there are a lot of third-party applications that offer that.
