How to find the RSS feed address of a Twitter account

In the old Twitter you could go on a Twitter user's profile and on the bottom right there was a link that says: RSS feed of "XYZ's" tweets.

With the new Twitter these links don't exist anymore. 

There is a way to get this link though. Therefore you have to log out from Twitter and go to your or another twitter account by typing the URL: http://www.twitter.com/anyUser. Now you should be able to see the RSS feed and use it.

For example in PHP to embed the feed in your webside as described here.
