title: Getting a list of usernames of Twitter followers
body: <p>I am trying to get the list of the usernames that are following a certain Twitter username.
  I can easily get a list of the ID's of followers by using </p>
  
  <p><code>http://api.twitter.com/1/followers/ids.json?screen_name=&lt;ScreenName&gt;&amp;cursor=-1"</code></p>
  
  <p>but then, to get the usernames I'd need to make a call for each ID to get the username with </p>
  
  <p><code>http://api.twitter.com/1/users/show.json?user_id=&lt;userId&gt;</code></p>
  
  <p>which reaches at once the 100 api call limit.</p>
  
  <p>Is there a more elegant way in which I can get all usernames at once by way of php?</p>
