title: PHP remove everything before last instance of a character
body: <p>Is there a way to remove everything before and including the last instance of a certain character?</p>
  
  <p>I have multiple strings which contain <code>&gt;</code>, e.g. </p>
  
  <ol>
  <li><p><code>the &gt; cat &gt; sat &gt; on &gt; the &gt; mat</code></p></li>
  <li><p><code>welcome &gt; home</code></p></li>
  </ol>
  
  <p>I need the strings to be formatted so they become</p>
  
  <ol>
  <li><p><code>mat</code></p></li>
  <li><p><code>home</code></p></li>
  </ol>
