title: Grab remaining text after last "/" in a php string
body: <p>So, lets say I have a <code>$somestring</code> thats holds the value "main/physician/physician_view".</p>
  
  <p>I want to grab just "physician_view".  I want it to also work if the passed string was "main/physician_view" or "site/main/physician/physician_view".  </p>
  
  <p>Hopefully my question makes sense.  Any help would be appreciated!</p>
