title: Remove everything before (including) the last occurence of a character
body: <p>Please help me get everything after the last occurrence of <code>/</code> using regex.
  My variables look like this:</p>
  
  <pre><code>http://domain.com/folder/subfolder/123456
  http://domain.com/folder/subfolder/678901
  etc.
  </code></pre>
  
  <p>and I only need the part after the last <code>/</code>
  i.e.</p>
  
  <pre><code>123456
  678901
  </code></pre>
  
  <p>Currently I'm using <code>/[^/]*$</code> but this gives me <code>/123456</code> &amp; <code>/678901</code>.</p>
