Twitter autoresponder bot

By Daniel15 (dan.cx) This is a very simple Twitter autoresponder bot. It requires PECL OAuth extension to be installed (run "pecl install oauth", or if on Windows, grab php-oauth.dll. If using cPanel you can install it via WHM). The authentication is designed for command-line usage, it won't work too well via a web browser. You'll have to sign up for an application on Twitter's site to get the consumer key and secret.

Could be modified to be more advanced (match regular expressions to answer questions, etc.)

Questions? See my blog post - http://dan.cx/blog/2011/06/twitter-autoreply-bot-dbznappa

Modified 2013-06-13 - Twitter API 1.0 discontinued, modified to use Twitter API 1.1
