title: Extract Twitter username with PHP
body: <p>Say, I have a direct URL to a Twitter post, like</p>
  
  <pre><code>$url="http://twitter.com/#!/YourName/status/01234567890123456";
  </code></pre>
  
  <p>or</p>
  
  <pre><code>$url="http://twitter.com/YourName/status/01234567890123456";
  </code></pre>
  
  <p>Could you please advise the simplest way in PHP (regexp, i suppose) to extract YourName out of these strings that looks something like that:</p>
  
  <pre><code>$account= ??? (???,$url);
  </code></pre>
  
  <p>Thanks.</p>
