title: Regular Expression to collect everything after the last /
body: <p>I'm new at regular expressions and wonder how to phrase one that collects everything after the last <code>/</code>.</p>
  
  <p>I'm extracting an ID used by Google's GData.</p>
  
  <p>my example string is </p>
  
  
  
  <pre class="lang-none prettyprint-override"><code>http://spreadsheets.google.com/feeds/spreadsheets/p1f3JYcCu_cb0i0JYuCu123
  </code></pre>
  
  <p>Where the ID is: <code>p1f3JYcCu_cb0i0JYuCu123</code></p>
  
  <p>Oh and I'm using PHP.</p>
