If you’ve ever wanted to display your latest Twitter tweets on a website, here is method to do that using PHP.

  9.  *
  10.  * Notes:
  11.  * We employ caching because Twitter only allows their RSS feeds to be accesssed 150
  12.  * times an hour per user client.
  13.  * --
  14.  * Dates can be displayed in Twitter style (e.g. "1 hour ago") by setting the
  15.  * $twitter_style_dates param to true.
  16.  *

  18.  * Hashtag/username parsing based on: http://snipplr.com/view/16221/get-twitter-tweets/
